hooked hull repair

[fins&gills]

Is it possible to take out a hook in the hull. the back of the hull on my glasscraft has a hook or bow down is it possible to get this out. i know the side stringers are made out of plywood,and the middle rib on the side has a bend in it, If I removed the stringer would the hull go back straight. The center keel stringer is 2x8 and is in good shape. The keel is straight and the body is straight. I have it on a roller trailer and the bend is right on the roller.

Has anyone done this. Will the hull go back or do I need to hit it with a sledge. I was thinking, I would change the trailer to a bunk so the edge of the hook is siting on a 2x6, hoping that this will make things straighten out. Thing is I don't want to spend a whole lot of time and money doing something that won't work. To replace my hull in this country would cost me about 2g, and be about the same age with the same potential for trouble. I would rather spend the money on mine, and have something I could trust.

For starters I would replace the rollers with well supported 2 x 6's, laid flat, from just behind the stern, to as far forward as the hull remains flat. The hook may relax out if you remove the pressure points. Just leave the forward keel rollers and any center rollers that would keep the keel from hitting the trailer as you load it.

The hull will either return to its original shape, or you can correct it when you press your new stringer down.

Re: hooked hull repair

changing it to a bunk trailer would help.. roller trailers are bad about causing hwta you describe.. there is no way to pound out the dent.. you will have to roughen up that area and build it back to level with fiberglass and cloth.. also if the inside stringer is soft it will need replaced

Re: hooked hull repair

<br /><br /> A couple of pics to save a thousand words.<br /> I don't understand how filling in will help won't it just turn a down hook into a down slope?<br /><br /> All old boat problems seem to come with a story, here's mine. i had a 72 65hp merc on the back that was a pain two times out two hundred bucks to fix two times out... Got rid of it and bought a "new" 89 75hp. Driving down the road for the first time, I thought I was going to see a motor sping of into the ditch. The "new" motor is twice as heavy as the old. transom rotten, need to get the rest of the year out of it before I replace. Decided to just laminate a piece of plywood inside to brace, cut floor and noticed plywood stringers kind of soft. Then I did something realy dumb I had a good look at the boat, and noticed the hook. Explains why I seemed to have a problem getting the bow up, had to trim the motor up too far. Here we sit do I fix or get out the sawsall.

Re: hooked hull repair

Ooh - exactly as I understood. You were planing to replace the outher stringers, wer'nt you ? When you do, just make sure the stringer is cut straight, like the keel line,and arrange for something to press it down to the bottom all the way. If no else solution, clamp a piece of 2"x4" across hull, to top of hull. Mesure distance from this wood down to hull bottom. Cut another couple of pieces, cut a notch in one end like a fork and use them to press stringer down to buttom is straight. With stringer in that possition, glass it to bottom 5 - 6 places along the length. Let cure and remove the supports.

Re: hooked hull repair

thanks G DANE will be trying this in a month or two depends on the salmon, west coat b.c. I figure nothing ventured nothing gained. this must be due to the roller trailer not enough suport.<br /><br /> My two cents transom saver (read, life saver) If it was not for buying a saver my holidays would be shot. Not a solution for a bad transom but it saved my behind, and if it can do that for a bad transom it also has to be good for a new one. Insurance for fifty bucks, for a life time not bad investment.

Re: hooked hull repair

When you cut the structure out, the hull will relax into the shape it should be. My hull had some warpage to it, and once I had all the structure out and no weight, it relaxed into its original molded shape. Bear in mind it was a stripped shell, much lighter. I then glassed in each stringer, one at a time. I did not glass the next in until the one I finished was cured. I checked the hull bottom continuously during the process. I also started with the outermost stringers and alternated back and forth, working my way to the middle (I had six stringers to glass in). By the time I was done, it was rock solid. This was all done while still on my roller trailer. I also readjusted all my rollers so they were under stringers, eliminating any future problems.

Re: hooked hull repair

It was your web page that got me to thinking that I could fix this thing myself, will be posting pics and lots of questions when i start this.Just like to thank everyone for the help without this I would not know where to start. I will turn the roller trailer into bunks when I am done, just makes sense to me the more suport the better. The pictures where taken after I had moved the boat ahead a few inches the bow was right where the roller was against the hull. Moved it because the new motor was heavier and the tounge was to light.
