    "Soaking out the epoxy externally. I read the best way to do this was to use a foam roller and do it wet on wet. Well it left a lot of sanding, at least 8 hours with a good orbital sander so I tested a bit by using the foam roller but using a painters technique of brushing it out while still wet. That made a huge difference. "

    You discovered a principle that has been talked to death on these forums, illustrated a million times on Youtube and written about by every boatbuilding book ever written ?

    Sweet looking main hull, looks fast just sitting there. Is it going to be folding or demountable? Maybe you could glue some foam on the bows of the Hobie and shape them to a reverse bow to match the main hull.

    Keep the updates coming.

    Cheers, DAVE

    It's coming along nicely. Keep pressing on, and keep posting. I'm interested too.

    Just don't let a cranky van diemenian put you off. :)

    tamas,

    Is there any more information on the "husky" design?
    I tried to google but only got your blog.

    I'm looking for something similar to build.
    Any contact point for your designer?

    Yeah, I can discourage anyone building a boat very easily. I've had lots of practice on myself. ;)

    I hope Tamas can do his research before he makes extra work for himself - on whatever job he does next. There is so much info available.

    I know, you tried it on me too. :p Not only you though; a couple of smarties on this forum were also dismissive. But of course I didn't listen, which seemed to greatly upset the said smarties.

    Anyhow, re my build, thanks for asking...:) My 14 foot cat is based on PT hulls and rig but rebuilt with a single centred board and rudder, mid-boom sheeting and lowered tramp. And I can report from racing today in 20 knots that it handles well and fairly zips along. The single rudder responded perfectly every time; I'd added about five inches to the blade and the centreboard to compensate for there being just one of each, and so I have some in the water when flying a hull. The weight increase over a standard PT is about seven kilos, but that differential will be reduced by my having one less each board and blade & gear. I had been using a smaller rig to date but returned to a sail close to the class size today, which really helped. Access to the board is vastly improved compared to the clumsy in-hull arrangement, and being able to get about in a normal fashion without crawling on hands and knees - which always seemed to me unseamanlike anyway - is a huge plus for ageing joints. And the mid-boom sheeting eliminates the need for convoluted gymnastics when going about. In fact, now that I've ironed out a few issues, I reckon it's better than the original. :cool: But I would say that, wouldn't I. :)

    Good for you - don't listen to the naysayers - just do it!

    The funny thing is, I wasn't naysaying anything - just snidely remarking on the technique he finally 'discovered', despite it being basic reading in the many manuals of epoxy layup.

    Even if someone cant read these days, a few hours on Youtube will tell you all you need to know.

    One consistent problem no matter what you are doing is when you "don't know what you don't know".
    I have many times appreciated a simple reference to a typical and well known technique that I didn't know about.

    If I started doing traditional wood boats, I wouldn't know where to start asking about techniques "everyone" knows.

    He still learned it for himself and was willing to share. I like that attitude above anything else.

    Michael,

    Thanks, I have been overwhelmed with finishing a SOF boat recently.

    From personal preference I would be looking for something round bottomed.

    I'm also a little puzzled about the equal length main hull and amas.
    My problem was that I was looking at another Thread and missed most of the discussion and the pictures of the hull geometry. I've finally caught up and need to study a little.

    Thanks,

    Marc

    G'day Tamas

    Any chance of an update? The whole concept looks cool - now it would be interesting to see performance information'
