    If you like you can read more about the Trimaran here. Bob Hicks (great guy) of MESSING ABOUT IN BOATS gave me the chance for an article.

    Got my cost down to $115 today!

    Another $15 and I'll be at the limit.

    Got the weight down to 133 pounds.

    I suspect 10 - 20 of that will disappear come summer's dry weather as a good part of that wood is stored outside.

    I can knock off another 5 - 10 come build time.

    We shall see...

    And now back to the Deutsche gesprachen.

    Your German is better than my English - thanks for your patience. But back to basics. I browsed about canoes and kayaks and their hydrodynamics and found a small E-Book: Hydrodynamik für Kanuten - http://ebookbrowse.com/hydrodynamik-mw-pdf-d338621577. It is written in german, but the most charts/tabular forms(?) are from "SEA KAYAKER" with interesting results of tests and of course in american language.
    Interesting for me are the speeds, the resistance (wave and skinfriction) and the power needed.
    Most important (as earlier here stated) is length. But interesting is that you need 72% more power to increase speed from 4 to five knots with a 6,10m (20ft) LOOKSHA II kayak (page 19). If you want to go seven or more knots the resistance will increase sharply and so the power needed may be 150 or more percent. It might be helpful to start a special training ???

    I'm all over it guys, I'll make it work.

    Thanks for the lead Manfred, I'll check it out (look at it).

    I'm now at 24' X 1', with an 8" draft. (7.5m X 0.3m, 0.2m depth).

    ~740 pounds (340kg).

    Almost forgot to mention the outriggers, 8' X 3" X 3"

    The hull is so flimsy, it relys on the outriggers for integrity.

    As you were.

    Manfred,

    I was unable to view the download.

    Would you send me the graphs and/or English of interest?

    Personal Message me if you like or just post them here.

    Your choice.

    Thank you.

    Tom, there might be another solution for you and your plans. Did you ever hear of Alberto Alvarez-Calderon F., California, and his TRANSONIC HULL AND HYDROFIELD which he has got patented (WO 2005/090150 A1) ? Alberto claims for a low resistance hull. If you are interested I will try to get for you more infos. DoppelKeil11.jpg DoppelKeil12.jpg

    Manfred,

    Thank you my friend.

    I am all over (into) hydrofoils but I think I'll save that for next year.

    All I have to do at this point is beat the second fastest team.

    I've paddled four of these kayaks listed.

    The numbers are interesting.

    I like the part regarding 25:1 l/b ratio.

    I was thinking my 24:1 might be too much.

    I am familiar with Alberto's boat.

    Rick W is not overly available and not always that helpful, but his boats are interesting.

    Remember, the challenges for me, other than a good design, are time and money - just like the real world!

    Regards,
