Hello to all,
I started the adventure for the construction of my cx 25, I hope in the many technical tips, and many moral aid.
publish 'some pictures for you to see how far they have come.
thanks bye
pardon the English use the translator

Hi Dalnilo, if you need help with the translation just ask.

Ciao Dalnilo, se posso aiutarti con le traduzioni non hai che da chiedere.

A 25' boat is marginal for a bow thruster. It depends on the currents and tides in your area. If they are strong in your area and I know from experience that there can be some high ones around Italy then a bow thruster makes some sense. If not there is no need for one on a boat this small. it also depends on how much room you have to moor or dock. The smaller the space the more you will need one.

So summing it up, it is really up to you as you know what your conditions are and how well you can handle your new boat.

You laminate the fiberglass with a round edge, just as you did and build a sharp edge with the fairing compound.

You can put a bow thruster but imo you don't need one, over here we have very strong trade winds and currents, mine is 3' longer and I dock this boat accurate within the "millimeter" using one outboard and no bow thruster, If I can do it anyone can do it :wink:

I can't give you a dimension, I don't know where to start to measure but, use the bow mold to check the length and shape.
It looks fine to me and if all your dimensions are OK, it should be correct.

In the second and third picture the fiberglass looks very "clean" (not sanded). What speed hardener did you use? How soon after fiberglassing did you put the fairing compound on? It looks like from the dates on your posts it could be around 5 days. With that much time in between (anything over 24hrs) I've been told to clean and sand the fiberglass to make sure the next layer of anything will stick.

I'm curious to hear what everyone else says. ...

There could of been some amine blush that caused the delamination. It does look like from the pictures that the fiberglass surface was very shiny indicating it had not been sanded. Sorry you had to deal with this. The adhesion appears so poor, that perhaps the cleanup won't be too bad. Otherwise your build has been a great one to follow. Wish you all the best in the continuation of your build.

Regarding cleanup, I would suggest using a blower nozzle on an air compressor if you have one. Follow it around with a plastic spreader to help guide the airflow, it should allow you to just "peel" it off with the compressed air, depending on the amount of gap. The filler used looks like straight silica and epoxy? That's the only explanation I can think of for why it looks so brittle.

Any time I see that Jacques designs a boat and makes the skeg optional I would put it on. It will help in tracking in various seas and in following seas also. It just makes the boat easier to handle. As you can see by the size it doesn't have to be large to make a lot of difference. I would go with one 3 meters, 9 ft long. You could go another meter longer if you wish, but don't go to long or you will affect other handling characteristics.

Could also simply run tape up both sides and hope it sticks to the other side enough to hold it in place, then trim with a razor blade. Then again I don't think the razor sharp edges are necessary on those skegs.

Re: My cx 25

I think the fear is that without a larger radius on the tip, your tape will bubble out and cause huge voids while curing, the tape/cloth doesnt like sharp corners like that which is why you have the fillets inside corners and sanded or routed radius on outside corners.

Sorry but what rays should I do? Should I just round up? The designs are sharp,

Re: My cx 25

Posted: Sat Jun 24, 2017 7:26 am
by BB Sig
I believe the radius needed is determined by the fiberglass being used. Thicker fiberglass needing a larger radius. I believe most times Jacques specifies a .5" radius. Too large is a waste of epoxy and too small is, well, too small. :D

Check your building notes to see what is specified. You can always sharpen the edges after the fiberglass is applied.

Re: My cx 25

Posted: Sat Jun 24, 2017 8:43 am
by Dougster
I'm wondering if you could skip the radius thing by doing one side at a time? Do one side, leaving an excess or overhang. Let that cure and cut the excess off cleanly along the sharp edge. Then do the other side. If concerned about the very edge run a thin bead of wood flour thickened epoxy along it and work it in with a stir stick, clean up with a rag, and touch up with hand sanding when cured.

For your opinion, (not considering the application of fiberglass) at the end is it more appropriate if I have an edge or rays?

Forgive my Crude drawing, but this illustrates the two methods you could use:
Skegs.png
Skegs.png (1.99 KiB) Viewed 715 times
Option A, you will want to "round over" the hard edge of your material so that the tape wraps around it. While it may look like it will wrap just fine, once the epoxy starts curing the material changes properties slightly as the matrix with the epoxy forms, and the glass and epoxy will become "stiffer" and try to straighten out somewhat against the hard edge.

and Option B (if you want to keep that hard edge) is probably the best way to make it work, without having the tape peel off of the hard edge during curing. You will want to make sure to have as little tape overlapping at the top edge of the skegs as possible, but to make sure that it touches, and stays together. This way could be kinda tricky in practice.
Once it cures, you trim off the extra glass with a razor blade, and sand it to whatever edge you prefer.

I would do a test batch first on a small segment of the material either way, to see what you are up against.

Also of note: The strakes may look like they are a very pointy trianglar shape in the drawings, but the note next to them says 2"x2" cut diagonally, and glued on the diagonal cut side (In other words the design calls for a 90° angled piece, and probably with the same radius on the edge as you would find on standard hardware store lumber)

I can laminate 12 ounce biaxial tape around the shape in your photo with no problem.
You can make it work also.
Don't overstress the fibers of the biax by forcing the fabric to bend.
Take your time, use plenty of epoxy and be prepared to fuss with it while it dries.
Do a test run on a sample piece of wood before you do your actual layup.

I wish I knew more to help you.
In my HC14 and FS17 plans, it specifies a 1/2" radius needed for the glass to be able to lay over.

Maybe your CX25 plans specify a radius size for the weight of glass you are using?

Sand down the point of your triangle to the shape of the circle on the outside, then glass it in.
Once that is done you can build up your point again with the appropriate filler to get your sharp triangle again if that is what you want.

Hopefully I am telling you the right thing, I have not done this, only studied alot :)

Let's not get too worried about strakes and spray rails. They are a good addition to a fast planing hull, not necessary on a slower one and the exact cross section does not matter too much.
The strakes full fill several functions. The most important one is to separate the water from the hull while on plane. This will happen with almost any section as long as the edge is sharp.
The strakes also help with dynamic stability: the tiny little bit of lift they provide add some stability but that lift is very small.
The last function is to divert sprays, again, no big difference between shapes.
Ideally, for the best lift, the surface should be parallel to the water but if I were to calculate the difference over the whole boat, we would be looking at something with 3 or 4 decimals.
For the best water separation, the surface should be angled a tiny little bit down but again, how much difference will it make?
To cut a square section along the diagonal puts you very close to the ideal strake. It will angled down a little bit and provide some lift.
It is a good compromise between water separation, lift and ease of building.
If you want more lift and less deflection, you can fill that corner as I see in the picture but I would not bother.
Each shape is good.
Two more points: you need a radius to glass them. Later, when faring, you should build up a sharp angle with resin plus a strong filler like glass strands.
That sharpness is more important than the angle.
Last point: don't compare to the strakes in production boats. Their size and shape is dictated by lamination requirements: you can't push glass in a small sharp corner (too much labor) and they don't want the gel coat to build up and crack. Do not compare, your strakes will be better.

thank you very much for commenting, I do not understand why nobody gives a comment either negative or positive. no matter, I think a more modern design does not change so much in terms of weight.
I have found many ideas to have a more comfortable boat, and in the end I will start from the things that I find most useful and functional for my use.
of course without disturbing the initial project.

Dalnilo Thank you for the compliment,for the record I wasn't responding to you but to Rich, he has "troubles" enough as it is going trough the first phase of his build, let alone making major changes like that, that is what I was thinking is not a wise idea.
As for your question, keep in mind that the CS as with other bateau boats is a very light boat, raising the sheer that significant and building a pilot house that high on top of it wouldn't contribute to stability or enjoyable characteristics, just my 2 cents but it is your boat you should do as you please :wink: 8)

I'm not making the numbers it is what it is, CX Stripped hull is approx a 100kg more at 865 kg.
The boat you were showing earlier is different from the CX or CS, it's LOA = 1 meter longer sheer and pilot house are significant higher.

Sure you can do that, if it were me I use a foam core for that.
But fitting in a 2 persons berth with a pilot house over it like shown in the Moda boat will make it to high and top heavy, at least that's what I think.
I would have liked that Moda much more if it was longer and wider more in proportions with the the higher sheer, but as always beauty is in the eye of the beholder :wink:

Hello to all,
for so much work I go a bit lazy, in my program I had thought to turn the boat by 2017, but I do not think I can.
put pictures of the little work I did.
what do you think of the vacuum process I use to laminate parts in photos.
It's the first time I use it, I hope the passion it takes to get it repaid with a great result.

Happy New Year to all.
I ask you for advice. I would like to finish the bottom of the boat so I can turn it around. what finish do I have to do? resin and graphite?

Hi Dalnilo, the boat is looking great. What to choose to finish the bottom of the boat will depend on how you plan to use it.

The resin and graphite that you see many builders put on has a purpose- abrasion resistance. Many areas around the southeast parts of the U.S. have beds of oysters, and if you're going after fish in shallow water it's easy to scrape up against them. If your boat will be kept on a trailer then this is an acceptable coating. It will not provide any resistance to marine growth, and it is susceptible to UV rays so needs to be protected from direct or prolonged sunlight. You'll never get as smooth a surface with the graphite/resin, because it goes on thicker than paint.

If you don't want to go with the graphite, and the boat won't stay in the water more than a few days at a time, then you can use marine paint, same as hull sides if you want to keep it simple. If the boat will stay in the water for extended periods, you do want a bottom paint and will want to ask around your area to see what works well for other boaters. It that's the way you go, you may want to paint your hull sides now and do the bottom close to the time you launch.

thank you for your compliments.
I'm undecided, the side I want to finish them at the end, because I work in a narrow space so I would ruin it. for the fund I would like to do something definitive. I think I keep it in the water for 6 months a year.
a question can I give a coat of resin with graphite and then cover with polyurethane paint?

If you are going to keep it in the water for that long; I'd go with a bottom paint. That is what I am doing on mine. I am going to use interprotect 2000 or 2000e and then Petit Hydrocoat ECO to the waterline. It will be a nice harderish finish that you would be able to clean without removing a too ablative paint. Ask the people where you plan to anchor/moor/dock what the preferred local finish is though.

what was your vacuum rate for your on boat vac work? I am going to vac glass onto my bottom 33', I figured I'd only go with 9" hg or so; just enough to get the glass flat and pull a bit of excess

If you are going to bottom paint before the flip make sure you select one that gives you a long window between painting and launching. Some bottom pains need to be in the water a few weeks after you paint them. I selected one that gives me 18 months to launch without having to reactivate it with fresh paint or sanding.

Danilo,

I am amazed by your build. Your bottom strakes look like what was on my previous 26 ft boat. That boat ran 42 kts with a single 250 etec. The strakes helped I think. What a beautiful job you are doing on her. The tanks look like they were custom built for your boat. How did you manage that? I assume all the stringers around the tanks will be glassed full height. You are going to have fun running the fuel fill hoses as these suckers are stiff as all get out.

Keep up the great job.

Danilo,

I think I would keep the tanks totally separate so you can fill each one individually and adjust your cg depending on your fuel load. You can have a fuel feed 3 way valve which you can switch which tank is feeding the engine.

Other option is to turn tanks around so that fill and vent fittings are near each other and get a 1-1/2 inch brass Y or T fitting to connect them.

If tank fittings are higher than stringers you have other issue you need to solve to raise the sole in this area.

Tom

If those tanks are polyethylene they will expand 2-3% of their size over the first month they have fuel in them. Make sure you have room for that between the stringer or it could damage the tanks or the stringers.

thanks for the advices.
I think tanks connect them in a single shipment, so I install less pipes.
as regards the boarding connection, I resolve by raising the floor by three cm.

You can't foam around polyethylene tanks for that reason.

Example instructions: https://www.jamestowndistributors.com/u ... docId=1025
IMPORTANT: Do not use foam to secure tank in place. Resin fuel tanks require a multidimensional expansion area of 2.3% at all times; foaming a tank in place removes the chance for hydrocarbon expansion and will void tank warranty.

Does that mean that actual tank capacity is variable? EX if you have a half full tank, the tank may expand inward making the "empty" portion less than the actual volume of 1/2 the tank capacity.

Or would that only happen if the tank was restricted from expansion?

Thanks.

I'm under the impression it's kind of a one time thing, and that once it's grown over that first month it will basically stay expanded, unless maybe you let it completely air out for a long time. I think if you restrict it from expanding outwards like its supposed to it may deform. All this is conjecture on my part though. Just what I've gathered from the manufacturers instructions and Boatowners Mechanical and Electrical Manual which I kind of consider the bible of marine systems.

I think you actually get a bit more capacity after this process is done, as it's expanding lengthwise not just getting thicker, not positive though.

The expansion and contraction is thermal. Boat in Bahamas and it is 100F the fuel expands and the tank expands.

The expansion of a 1 meter polyethylene tank from 23C to 40c is about 0.3cm

It isn't a one n done.

If the temperature drops to say 6C, the tank will go from the expanded size at 40C down to normal size at 23C and then shrink to 0.3cm below a meter at 6C.

Danilo - leave a good size gap between the tanks; like a full inch or at least about 3/4" minimum.

And no foam.

Foam is also not advisable in ally tanks. The tanks needs space for thermal expansion.

That may also be true, but polyethylene definitely expands when exposed to gasoline.

From Moeller as an example:
Allow 3% expansion of the fuel tank in all directions. Hydrocarbon swell occurs when gasoline or diesel fuel soaks into the fuel tank material. (Example: Initial size 40"L x 24"W x 18"H = Expanded size 41.2"L x 24.7"W x 18.5"H) Design the fuel tank compartment to allow growth equally. Hold down brackets / braces must be installed to prevent damage to the fuel tank even after hydrocarbon expansions occur.

Thanks. I learned something today. I couldn't understand how the amounts were so much lower than the allowances I am using on my own build to meet 2.5%. I have a 47" tank and have a 48" space, so I am just a tad over the 2% amount. The tank is surrounded by bulkheads and they aren't moving. The good news is I have an extra inch on the width as well, so that will give me a little extra, but in the wrong direction.

Anyhow, hopefully with all this advice, Danilo will build properly.

I would defer to the instructions of whoever manufactured your tank. Generally tanks like this are mounted on a hard surface with neoprene strips between the tank and the support.That would be a lot of weight to put foam under and I wouldn't want foam up against a fuel tank myself anyway. But whoever built the tank should have instructions. Personally I wouldn't foam that compartment at all.

I think the rubber strips are something needed for aluminium tanks. I do not think they are needed for plastic tanks. But as advised check with the manufacturer and do as they say.

It really seems they were built for your boat, what's the capacity of each one?
Raising the floor of 3cm is very easy, just add a wood strip on the top of the stringers and you're ok, in a big boat like that 3cm is nothing :wink:

A vented tank is required to eliminate thermal expansion. All the expansion on a poly tank is chemical if vented. The liquid fuel doesn't shrink or expand with temp change, it's the gas vapor above.

Dainilo,

Those are very nice looking eyes. I think placement of the stern eyes depends on what they will be used for. Is this boat going to be trailered? If so, I would place them about where you are holding them. What else would they be used for? If for towing someone, I would place them higher. I am not sure about using them to lift the vessel, but if that is the purpose of having them, then place them higher as well.

I placed mine on the FS17 about 2 inches down from the top of the transom and about 3 inches in from the sides.

Your work is looking great. What a huge boat.

P/S I lived in Naples as a boy for 2 years while my dad was stationed there.

Good question....
I am not sure, but I think I would glass the stringers first, then after it is cured place in the bulkheads.
Like I said I am not sure, and though I doubt it really matters too much, my logic is that you have long glass beams if you glass the stringer all at once, where if you have the bulkheads in place it breaks up that long beam and is just wood in areas. I dont know though, I am not the designer, nor am I an engineer :) Hopefully someone smarter than me can help you with that question.

Check your plans, it should say tape the stringers first and then the frames. Should also tell you what kind of tape and if you layer them.

Re: My cx 25

I'm by no means an expert. That said, In my minds eye, I see the stringers as the backbone and the frames as ribs.
So to me I'm glass the stringers first to spread as much strength along the length of the hull. The the frames go in and get glassed
To stiffen the structure as a whole. Remember I'm not a pro but this makes sense in my head, and that in and of itself is scary.

Looking great, Dalnilo! You want the bilge pump at the lowest point that water can collect, and generally the slope goes toward the transom, so as far aft as water can go should be the place.

I think so. this and what the project says

15. Topside longitudinal stiffener is required from frame E transom.
Typically made of 13 of a 51Ø PVC pipe fiberglassed with 1 layer biaxial tape or 2 layers 102mm woven. Stiffeners fits between frames

the foam does not touch the tank because I put the rubber around.

good morning,
I wanted to ask why I have already consumed 266 kg of resin where am I wrong? I haven't finished the construction yet, maybe they will consume another 30 kg.

This is particularly important for a large boat with a cabin. I calculate the BOM based on the hull with deck and framing then add the cabin supplies but there many opportunities to use more resin.

yes, actually one more layer makes the difference, if then we put the errors, a little more putty and accessories, thanks Jacques

Aluminum frame? Yes but its the job of your fabricator to make it sturdy enough and to recommend good anchoring points.

Stationary use will be fine but some CS25 owners have installed small towers.
The boat can take it.

the sides of the ttop I would like to make them in foam is possible.
as for the cabin cover, can it be extended as in the photo? they can use it as a sunbath

I think your first side laminate is too stiff to torture well.

Is that the goal? 200g no mat will torture easier...otherwise you may have trouble bending..

Also, at the intersections; you can make a 3mm relief cut with an electric planer and avoid a fairing headache on the exterior.

you recommend the single motor to be assembled, from the project it says single 250 double 400,
can I mount a single 300 4 stroke?
what brand?
is the 300 excessive?
what maximum weight should a single motor mounted on a bracket have?

I answer myself, I assume that I can also mount a single motor from 250 min to 400 max exactly? it does not change whether single or double.

You have a choice: single engine or twin.
I recommend a single 250 HP. Check the building thread of Curacao Peter, he was happy with a single 300 HP.
My original recommendation for twins was 280 as in two 140 or 145. Some have installed up to 400 HP (2 x 200 HP) but I find that excessive.
Those recommendations are my opinion. The structure, transom and bottom can take any of those combinations.
