It's a small world - WBF is a good place to be as well!

The core-sound looks marvellous. Very classic! Not familiar with the design - did you build it as a SS&G? 7 months is good! I think my cutter will take at least 5 years.

'' It's a small world - WBF is a good place to be as well! ''

agreed, I chose this design due to it's success rate in the Everglades challenge ( a US type raid).

7 months due to the fact I'm retired and now have the time, the main hull is stitch & glue.

I've found some info on the rig - very interesting! Do you like it? Do you think it is possible to build as a SS&G?


Those of you that have built SS&G versions of these boats - how did you modify the plans to allow one step gluing full-size panels? I would like to avoid the scarf in the middle of the panel. I believe one way is to make a scarfed full-size pattern and use that as a guide for the gluing of the full length strips. Any another way to do it?

'' I've found some info on the rig - very interesting! Do you like it? Do you think it is possible to build as a SS&G? ''

I think it's possible but far more labor intensive in SS&G.

Last fall at the "Sail Oklahoma" event I was fortunate to meet with the boats designer, Graham Byrnes, who is a very experienced sailor, long story short he sailed my boat (I was passenger) and to say I was impressed would be a gross understatement. He had the boat hauling butt and even planing downwind . After this he pointed out several things I could do/change to improve the whole package, things I didn't see until I was shown. So I'm now doing these improvements. and looking forward to warmer day's to get out and learn more about the boat.

As to gluing full size panels, I made templates from real cheap plywood,to verify diamentions, then simply traced them onto painters paper on my 16' x 2' work bench, covered that with clear plastic, then glued up the individual strips staggering the scarfs as I went (panels were made oversize to allow for errors) then after glue up traced the templates back to the panel and cut to size. I hope that all makes sense to you. ?

Could not tell if you had full length strips on your Blue Fin parts or did you stagger smaller ones?

MM,

Everything makes sense, using plywood pattern was my first thought!

Matt, thank you for dropping by! The plans are really nice!

All strips are full-length so far. Slowly grown spruce is cheap in Sweden :-).

I'm really impressed by the plans and the instruction, great work! Would it be possible to provide a table of offsets togehter with drawing QA2? This would save ss&g builders a lot of head-scratching and it wouldnt be necessary to first do plywood pattern...

I'd like to make some birdsmouth paddle shaft's and mast's using spruce.

I really do envy you with that spruce. At least where I am Western Red Cedar is readily available, :) and a lot less expensive than marine ply,

Well, I envy your WRC, beautiful wood! What design is the sailing kayak? Looks like a LOT of fun!

Matt, thank you for considering. If possible, the offsets would help a lot!

, the Tri isn't one of his designs and I don't want to offend him by listing competetive Info here.

I will say that the outrigger which clamp onto the gunnels do work on Matts boats as well.
