So many good pictures, love this one,



Also love your chess board and map, lots of great detail and art going into your projects

She does'nt know yet she will sail with us

Hi Guys, hope everybody is fine on board...

On our side, we did a little break with the construction as we didn't know how to build the mast and adapt a sail... We have taken this time to study a bit more about navigation. And spent some time in the beautiful Brazilian coasts few pictures at the end of this post...

But in November we pretend to finally sail... and wish to get some inputs from you to help us to finalise as soon as possible as we fell a little bit blocked at that point...

We already have the following elements, and now need to build everything together...

- Mast Partner and Mast Step are ready



- Aluminium Spar in 2 parts that will be joined: 3m + 3m = 6m total



- We bought a Laser Sail that have almost the same exact dimensions specified on Jacques' Sail Plan (Marconi)

• Luff: 5,10m
  Foot: 2,70m
  Leech: 5,50m

- And have also already installed on the boat all the SS accessories (swivel block, eyebolt, to attached the halyard, the pair of shrouds and the SS cable on the transom.

Our difficulty now is to understand how to join the sail and the mast. As our sail is from a laser, we could actually fit it directly on the mast, as we did on the picture... But with the pair of shroud, this is not an option anymore... or should we pierce the sail at the height of the shroud attachements?

However, we understand the best option would be to be able to raise the head of the sail once the luff is attached to the boom along its length.
Should we consider to instal a mast track slider?

Many thanks in advance for your orientations...

Nice progress guys!!!! Jeff

if you want a fully raise/lower sail then you will need to do a track. But I don't think you will need a full track.

Many thanks Jaysen, do you think half track would be enough? just in the upper part of the mast?

You’d still want to secure the lower section. But using track above and rings lower would make it easy as you wouldn’t have to worry about alignment of track on the mast (if I recall you have a two piece mast).

yes it is a 2 pieces mast, so it would be definitely easier to use track only above... i am also worried with the alignment. Many thanks for your suggestion

We were also considering another option, but i couldn't find any information about it, so maybe it is a wrong ideia... What about using a steel cable attached really close to the mast as an "external track". This way, we won't have any trouble with the 2 piece mast alignment... but in the real life, i don't know if the cable would remain as closed as the mast as we imagine in this scenario....

[Jaysen]

That’s the same principle as a stay sail. This is how most fire sails actually work. you need to get that stay really tight which will put a lot of pressure on the mast. But this is all small scale so we are to talking tons like in a larger boat. I would.
1. Put a guid block on top of the mast.
2. Put the bottom stay anchor ON THE MAST as a through bolt.
3. Run stay from aft anchor, over guide, down to other anchor.
4. Turn buckles on both anchor points.

You still need the halyard block at mast head to raise the main. If you want it to ride smoother make sure the anchors and guide block at top give you 1/2” (2cm) clearance for the sail hanks.

Tony (terullian) or Bob (Capt Ub) May have better ideas. They have a LOT more experience than I do.

Sounds like an adventure. Take pictures.

Many many thanks Jansen, sorry for the late answer, we were out of sinal those days...

I think we understood... but .. as it is our first construction, we have some nautical vocabulary terms to learn to be able to picture out exactly your recommendation but i guess we've got it
Would you suggest a video illustrating your answer so we can be sure?
