    I'm basicly trying to keep this project low key (away from the forums) for the most part......until I have some pictures and video to post of me flying along up in the air and out on the wire. Everyone has seen build pics before. All the really interested people seem to keep track of whats going on through the blog. I get E-mails everyday full of idea's and questions, so thanks to those sailors for their support, Its coming along and will be done when its done.

    After hearing that doug has been banned I am rearing my ugly head again. A lot has happened since I've been around these parts. I have finished the hull plug and just glassed the deck tool as well. Just need to build the foredeck plug and it will be on like Donkeykong. I have a couple questions for all you spray buffs out there:

    After all the moulds are built and glassed I want to coat them with Duratec sandable primer as my tool finish. Is this brush or rollable or do I have to shoot it? Are there any issues with humidity (some of these coatings have bonding issues even with low humidity levels). And Do I have to buff it all the way to gloss or would sanding to 400 or 600 do the job? Thanks.

    I was talking with Paul Mac today at the Onetangi Sports park. I taped a interview where he talks about the foil being the future..

    I will post it once its uploaded to youtube.

    Did you know that Dan is selling sets of foils?

    I would love to see that interview. Who is Dan? is he selling moth foils? where can I see them? (Pricing?). I'm looking for a set of foils (mach 2? Illiet? aardvark? Used?), the new plan is to put a square main foil box in the hull instead of a foil shaped case so that I can switch out foils at will. I plan to start with a moth foil set based on the fact that they are working well on Bruce Gaunt's 16' trapeze foiler in Aus and all the controls have been sorted. Then move onto my own optimized foil set.

    Great stuff.....I don't think that the R foils would work very well on the SR because the numbers don't match up very well. To much lift area (drag) for this projects weight/sail area. I'd rather have a little less lift area than I need(moth) than to much (R). Using the moth foils I might give up a little on early lift off, but higher top speed is an alright trade off I think. I often kick around the idea of building an R mould when I'm done with this frankinstien. I think it would be a great class to introduce to the States. (***Yes I'm crazy :D ***) Well, I'm off to sand fresh fiberglass.

    Haven't been to these parts in a while, but the tools are done and ready to lay up, spent the day looking into vacuum infusion. Really leaning that way.

    Are you going to lay up a hull off the hull plug or lay up a mold and then a hull? Good luck!

    Lay up off the plug for this first one, I know its not ideal, but its the easiest as far as tooling is concerned. Just want to get this first boat up and running, so I can get a feel with whats going on with it. I have plans in the works to build a female clamshell mould next. (to a new design from the same formula)

    ===========================
    I've totally changed my mind on this -at least for small multihull foilers. Are you going to use a gantry, Sam?

    Yes, a 50cm gantry. The hull has also been cut down to 3.85m proper, so should be 4.35m with gantry. It was just a little long, so I cut it down some. 10cm off the stern and 5cm off the bow. I am also cutting the beam down from 70cm to 55cm. And adding tramps.

    I'm also working on the class rule. I'll post it here soon for input

    ---------------------
    Looking forward to it. Suggestion: allow the same total overall length with or without a gantry. Allow sliding seats-whats the harm? Allow more than two foils-again-whats the harm? Don't restrict beam-maybe just restrict crew movement?
