From the pics it looks close...

Make sure there is nothing underneath, like the stringers or what not, keeping it from settling all the way down...

I Think, you might be able to persuade it back on with the mentioned ratchet straps and a little help from an assistant with some gentle prying...

The other thing you can try is to use a couple of floor jacks with wood to protect the hull, and jack up the two outer keels...that looks like where most of the problem lies...they may have sagged, and by jacking them up the weight of the boat might pop everything back together...

Just make sure that if you need to take it back off, you secure the hull in that shape...

Good Luck

It almost looks like the Trailer bow stop (rubber stop mounted on the trailer) is pushing the bottom of your hull up just a bit. And your vidio idea sure makes great sense to me. That rubber stop also looks like it could interfere with you pulling the bow back down and into the right position. Might need to pull the entire boat back a couple inches on the trailer, then pull down on your bow eye as you spoke of. I have never done this before either, so this is not experience speaking, it just seems like you are making good sense. The boat looks great BTW

What "greenbush" said sounds about right... back the boat off of the bow stop, do your pulling and tugging, don't forget to try and use a ratchet strap around the entire tri-hull area, to help squeeze everything back together...it should all go back...

OK, now for the WARNING!...;)...if you are going to be taking the cap back off at a later date, don't get your self in the same predicament by NOT properly supporting the hull...while it will probably flex back into shape now...when you take the cap back off and re-do the stringers and bulkheads, you could warp it badly enough out of shape that you will NOT get it back together...

Creating a support system for the hull does not need to be expensive or complicated...just make sure you provide enough support to hull to keep it from flexing...look through my thread for some really simple ways to create the support you need...a few hours of time and a few bucks in materials spent now, will save you tons of frustration, aggravation and mental anguish later on...

Here are a couple of links that show what I did... http://forums.iboats.com/boat-resto...ve-necessity-pride-521706-28.html#post3752005 ...

You could do a lot of similar type bracing while it is on the trailer and use the trailer as part of the support system.

OH YEAH!, I almost forgot...you definitely have to add a piece of lumber between the two consoles to keep them from getting wh:eek:acked out of shape...

Best of luck and have fun!
