    Thank you guys

    For the first time I don't feel that everyone is trying to make me feel small. I really want to use this beautiful hull, and save her from the grave.

    However, my wife is with child now, we have a four year old girl and we want to have a few more before we're all done. With that said, I need to have a boat that I could possible work on in the back yard, keep on a trailer and then launch at the local ramp or marina (Travel Lift). I know that this sound silly to keep a 40’ boat on a trailer… I don't want or need a 40'er. I’m now also thinking of cutting her length down. If I can use even a small section of the existing hull to build a boat that will fit my needs then the expense to save the hull from the chopping block is well worth it. At this point I don’t care if she ends up being 26 feet long and 8 feet wide…whatever will make a useable design.

    Thanks Gilbert for the ideas on with FreeShip. All the hull designs that I found on their website all have very low TMC’s. I guess that either no-one can design a boat to be stable or I’m weighing too much on this number…

    I’ll keep reading and learning, but I’m running out of time. I have a deadline for the Trailer to be custom built and the owner wants the boat moved by end of April…Thus my efforts to get some experts to assist in the re-design of her hull.

    Any ideas would be helpful…thanks again.

    Reduction of TM

    After checking the first three models I realized that I was using the same Draft for all three cases. Different displacements and thus different drafts…after checking the TM on the first studies should have been a reduction of 20% vs. 40%...

    After a tweak of the design and comparing the scaled down version of the spray the TM difference is 9’ vs 10’ or just a 10% reduction.

    Should the TM be a percentage of the LWL? I still have a lot of reading, but what other software is available to assist in balancing the sails and keel properties?

    Thanks again…

    I cannot change the way of the wind, but I can adjust my sails.
