    What are you doing? You need to consider the THE FORCE!

    What you need is a second pair of floats and beams that can fold out in an X! A quintuplemaran! The vent is only 2m diameter -that's the size of a womp rat so turn your computer off and use THE FORCE!

    Hahaaaa... Yes Sky-ratt and Lord Dooku, I will use the force of Divinycell to build my battle ship tomorrow!
    Actually I got my order today of 20m2 of Divinycell. The weekend if saved :)

    Cholsson i thought you have given up on building a boat and have decided to build a medieval plough, just one ripper in the middle with a laser cutting edge or is it an ice carver / breaker? Powered by the wind.

    Wayne, the TC601 is looking great! If you're able to have a small cabin without killing the weight and without reducing the cockpit to a small bucket that drags the stern with more than 2 on board, even better.

    I'm curious... what do you think it would cost to have one of these professionally built? All up: the boat, appropriate rig and sails (main, jib, downwind headsail), foils, and decent trailer?

    Really really busy bashing my head against a brick wall at the moment with work, seems to be taking all my available time, darn.

    Back to the TC601, it took 2 of us working 40 hour weeks, 2 1/2 months to get to the stage I'm at. I think with the revisions we have in mind and bare in mind the first one built sorts out all the problems with the plans and develops the way to build, that I think someone used to building in foam and simply following the plans, would knock 2 -3 weeks at least off that. Thats your labour hours then, about 800 hours or maybe a little less, I would guess . I think about 200 more hours would suffice to complete, maybe less but sorting out the rigging, mounting rudders etc is time consuming, but once the first one is done then that too should come down.

    I'm into about £ 3K for materials, but again if you wanted to build in glass and vinylester that would drop a little. A good donor boat is about 2.5K which will give you everything you need to complete it except beams, I'm using rolled gently arched 3" ali tube which should be here this week to get underway again, but again I paid a little over the odds to have good looking beams rather than straight sections ( £ 52.00 a 5.0 m length ) with adaptors at the Ama ends, I do like aesthetics.

    Hopefully that would give you a base figure, I think its the labour costs that will be the project killer as for the same cost you could probably buy an older F24 or such like, yes it will weight 3 times as much, but it will be as fast, give the same accomadation, but will have you up and sailing in an instant.

    Thanks so much for your detailed response. It's so irritating when trivial things like day jobs get in the way of experience of life things like sailing! :cool:

    So, $8-10k (USD) for materials and 800-1000 hours of build time would yield a gorgeous 20' trimaran. If the latter part of that (build hours) were possible with the rest of my life, it's not a bad deal at all. A professional build would require a "that's exactly what I want and am both capable of--and willing to pay for--exactly what I want" situation.

    You wouldn't expect a TC601 to perform much differently than an F24 MkI?

    I certainly appreciate your eye for aesthetics. If you're putting that much effort into a boat it's nice to end up with a beautiful result!

    I think everyone who has built a boat from scratch would say the same, if you want to go sailing then just buy a good quality boat, put the bill on your credit card, work a few hours more each day, and voila you have your boat.

    But if you want the joy of creating something in your spare hours at home and enjoy working with your hands as well as your mind, then building a state of the art boat that you will really enjoy and will reward you for your efforts, the the TC601 is right in the sights of such a project.

    The whole project was all about finding a boat build that could be done at home with limited facilities and in a simple way. The sheer lines are all soft curves, the length will fit in most home garages, the method is simple and yet the materials are state of the current best, the weight is just enough that one man can turn it over in slings, two can lift it about ( although its bulk really is better with three ) and it will carry 3 -4 people in comfort on some pretty fast day sailing + the nippers and good ladies have just enough protection to not feel that its a boys bucket and chuck it boat.

    The final clincher for the better halves is almost for sure the boat will be worth considerably more than the materials you have paid for it, when its only real competitor the Pulse 600 is well over 35K in the UK then a comparible boat with a larger cabin and probably about equal speed, built of better materials and weighing considerably less, must be worth 20 - 25K surely.

    Very impressive Wayne, I looked through your blog photos, nicely documented record of the progress.
    I can relate to your line of thinking. When we became interested in sailing we used to buy and renovated used racing dinghies and keelboats. We carried on doing this until we had enough sailing skill to justify buying new racing 505s in the UK. These boats were built by skilled people with hightech construction materials. Although we lacked the materials, skills and the time to build our own 505's, there were a few were gutsy people that built their boats from scratch, not only did they smile a lot they were equally fast most of the time.
    At the time our excuse was that if it is new boat we could not blame it if we sailed badly.
    We also built a few IOR racing keelboats when that was the fashionable thing to do.

    My reality check is:- when the boat is launched the first sail will cost you what it cost you to get the boat on the water, the next time you sail it will be 50% of that and so on, it is a serious motivator to make sure that you continue using it as often as you can.
    That said:-
    I have found that if your own sweat is invested in the adventure instead of just your after tax money, and if it is beautifull and it sails properly, I can easily convince myself that the experience was worth all of it and so much more than that from day one.
    Our 4.6m trimaran was built in a proper boatyard, it is still as much an experiment for the boat builder as what it is for us. There are many things that would have been done different if we knew what we know now, that is the process of evolution, we are learning all the time.
    Regardless of that ongoing process:-

    I think How it makes us Feel is priceless.

    That is what I see if I look at your pictures.
    Good luck with the construction, hurry up, summer is on the way!

    Nice building but it looks very small beam, comparable to my Strike 15. Not very powerful in comparison with my Strike 20 !

    Patzfran reported today that he sailed his Strike 20 for the first time yesterday. Very sensibly he was overloaded with lots of tools and spares never mind a dinghy plus outboard "just in case"

    Even so in light winds and three crew he recorded speeds over 12knots and said it was a powerful stiff boat

    He is an Acat sailor and has had many trimarans in the past (Twiggy, Tremelino etc so has a good knowledge base)

    Sailing Photos will be posted when I get them
