    Have decided now, thanks to you all to take the boat out of the water! Will be putting it on a trailer and then support it by various blocks, presume this is the best way....

    Good decision. One definition of a good friend is one who tells you what you need to hear, rather than what you want to hear. I think you've heard from "a few good friends" here.

    It was the constant change in hull support that was not good in the tidal flats, since your is not a 1 or 2 day project. Support the keel(s?) well and there will be less weight on and flexing from the other supports.

    Good luck!

    This is actually a similar problem they have on major aircraft structural repairs, of which I have designed many. When the aircraft is on the ground the weight of wings and engines puts loads on the center section and fuselage very different than when flying. Seldom are the large assembly jig available to hold the hull in shape when doing a structural repair. A change in the aircraft shape means serious flyablity and stablity issues at over 500 mph speeds!

    The solution for field repairs is to 1) temp brace the structure as best as possible around where you are removing the part(s); 2) replace only one major part at a time, leaving as much of the adjoining structure in place as possible; 3) and then verify you are maintaining the original shape before, during and after each replaced part. If you have a stout hull, and follow this procedure, I do not think you will have any problems.

    Good luck.

    Elliot Dont get depressed, that the last thing you need . Your doing a big job and you need interest and motivation. I don't think you have harmed anything, its not like you have took the whole deck off.

    If things get wobbly brace it , thats a peice of wood with some nails, (dont hammer them right home).

    You know when boats are made, most are fitted out when in the water. Theres a reason for that.

    You would'nt dream of connecting a shaft to an engine out of water for instance.

    When you get the boat out ,--level it up so that you can use a spirit level instead of measuring.
