Lori,
A finned roller is basically an aluminium tube about 10mm in diameter with fins about 4 - 5 mm long running the length of it - it is for consolidating fibreglass - may also be known as a paddle roller - I don't know if you can get them in the states - here's where I got mine

Larry - thanks for the kind words - your advice is paying off now!!!

Yes, they can be found here. West Marine, Hamilton's or Jamestown Distributors has them. And I'm sure others do, too.

Well,
I'm here at the end of my building week and I'm fairly pleased with what I've acheived so far...
The hull is assembled, mast step nearly finished, centreboard trunking is installed, seat sides are in place and I've fitted the cabin floor...
<img src ="modules/Upload/richstrat/cabin.jpg ">
I thought I'd experiment with pigmented epoxy as the final coat in one of the side tanks - I think I can say it was a failure!!!
I've filled as much of the voids under the floor as possible with drink bottles - I will foam around these to give it the rigidity I want
<img src ="modules/Upload/richstrat/bottles.jpg ">
Here is the fitted floor - the holes are there to fill the voids with the foam
<img src ="modules/Upload/richstrat/floor fitted.jpg ">
As you can see, I've moved quite a way from the original design, but it suits my purposes better...
My back hurts now so I'm off for a long soak in the whirlpool!!!

The bottles help you save on floatation foam.
Rich, I have a question about the bow area: Is that storage area, or a kind of cuddy cabin? - I can't make it out - looks almost to big for just storage.
If you don't mind, I'd enjoy an 'up close' pic of this area if you have one handy.
Btw, that is some superb work you are doing there. I'm really looking forward to see it finished
Thanks,
Stefan.

The bow area is kinda large, but that seems to be the way it was designed. I must admit I had the same thoughts about a cuddy - when the boat was upside down and I was crawling around threading the zip ties, I got into the bow area and realised that it was not far short of fitting a v berth! I'm 6ft 2" and my legs were very slightly bent to fit in. Perhaps Jacques should consider a stretch of the AR15 for this much promised weekender?
Anyway, it will turn out to be a very generous storage area, plus the spinnaker sock will fit under there somewhere...
Next photo session, I'll take a close up!

cleats
Hi Rich,
Boat looks great...mine is still upside down waiting for me to tape the outer hull.
What size wood did you use for your cleats and what kind of wood is it?
Are you going to use the same type for the rub rail?
Jay
PS. Your pictures are really helping me see what I need to do and how it will look. Thanks

The bow area will be where the chute is stored when retracted.
There is a strong design reason for the fullness as well. If the bow does not contain enough fullness, it will bury going down wind creating quite a spectacular crash (bow goes in, stops, transom goes over the bow, crew goes flying - I will have to find the film loop of it out in internet land, seen a bunch of them). From what I have seen of Rich's pictures, it seems Jacques has taken a more conservative route, selecting a fuller bow to prevent such unfortunate experiences.
It is an interesting tradeoff. You want a fine bow to allow rapid acceleration and hence rapid transition to planing, but you don't want it so fine that downwind crashes are common. The i14 folks have developed a T foil for the rudder which they report greatly reduces the tendancy towards nose diving - don't think you need but an interesting tidbit.

pitchpole videos
This is a little bit off topic from the AR-15, but to Larry's point about pitchpoling, here's a cool video of a cherub flying along (man, that's FAST sailing) until it hits a wave at just the wrong angle of attack, and then YARD SALE!

It doesn't literally go head over heels, but you get the idea. Wild ride, huh?
I remember having come VERY close to pitchpoling on a Nacra 5.2 catamaran. We were flying along on a beam reach, lifting the windward hull in and out of the water, when all of a sudden we buried both bows, lifted the rudders out of the water, and sent both crewmembers flying forward like bait hanging from the trapeze wires... It was pretty scary the moment it happened, but once we realized we were ok, we just burst into histerical laughter and high-fives. Talk about an adrenaline rush!

I never pitchpoled in a dinghy but did some spectacular loopings with a Hobie 16. It must be worse with a Nacra!
