1978 glastron 14' v-140 skiflite restoration

[kfx400kid]

Hello everyone, I new to the site and need some help with some work on a friends boat. He just purchased a glastron and it is in need of some love.
The previous owner layed a new floor over what was there and when we pulled it up cause the screws were rotten that held it to the stringer, we noticed a drill hole thru the hull so another fixed added to the list.
We are going to replace the stringer, floor and the transom needs some fixing. Its just the fiberglass that needs repair as the wood is still good cause we did some core checks on it and was still solid.
The stringer is shot so we have taken that out along with the whole floor. I have a few ? about the bilge as I noticed that there was two holes drilled into it but were up high and if water go under the floor how is it surpose to get out.
I will post pic of what needs to be done and really really really would like some help to have it done as best as we can. I have experience with working with fiberglass from work, but not restoring boats so laying glass is not a issue. I just need to know what to use were on the repair's.
I have done a lot of reading and have ideas on what needs to be done but just want to be sure. It only going to be used as a fishing boat to have fun as we are sick of land fishing. Well hear are some pics of what needs to be done.......

Welcome to iBoats!
Lots of options. You can cut the splashwell at the gunwales or you can remove the cap to get to the transom. The center Keel Stringer appears to need totally replaced. You can use ext. grade plywood for both the stringers and the transom. I'd recommend Polyester resin for the rebuild. These two links will be helpful for you...

Thank you woodonglass, The transom is not being replaced just repaired as the wood is still good, is just the cap needs some fixing in the corner, we are going to replace the stringer and floor with new wood and glass. As for the bilge area should I cut holes lower than were they have done to allow water to get out from under the floor. That's why the boat rotted out cause the water could never get out from under cause the holes were placed to high in the bilge. But if I do put holes lower when you wash the boat water will get under the floor from the holes rite, but if the boat is lifted up from the front the water should run thu the holes and into the bilge and out the hole, sorry don't know what the hole is called that the plug goes into on the out side of the boat. I am new to boats so I don't know all the correct wording to what things are called on the boat, I know a few things but still learning as we go along. The original floor was 1/2" ply so that's what will be going back in and the keel stringer was 1"x8" the highest point x 10'. So we will use 1x10x10 ripped to the rite shape of keel and deck. I plan on using 1/4" foam spacer's to space the stringer off the keel and gluing it in with pl construction adhesive. Then making a peanut butter mix and filleting it in and lastly capping it with some sort of fiberglass matt. I know all this from this awesome site and reading other post. Just want to make sure I am going about it the rite way.........

You say the transom is good. Have you drilled into it and checked the shavings to ensure that is the case? Better to do it now to confirm. I'd use plywood for the stringer instead of a 1x10 but that's up to you. I'd also bed the stringer with PB only and not use the PL. Again that's me. I'd use two layers of 1708 to tab the stringer to the hull and then cap it with CSM. It's all in the link I provided above. As for the bilge, I plug both the holes and then re-drill a 3/4" hole down as low as you can and then use a compression plug to plug it. I make the hole on side of the bilge and then I'd make a Weep hole in the stringer right in front of the bilge to allow any water to drain to the sidew where the drain hole was. Are you planning on installing any flotation foam?

Yes we have core checked the transom down low and was still good, wasn't mushy like the stringer was. As far as the stringer were going to use the 1X as the longest piece of plywood we can find around hear is 8' and would need a 10' so would have to add 2' to it and that would be more work. I really appreciate your help and I am trying to stay by your suggestions and the link you have provided. Yes we plan on foaming the hull once the stringer in and all glassed up and for the bilge there is only one hole in the transom for the bilge to drain but the hole's for it to drain from under the floor into the bilge are about 3" from the lowest part of the hull. That why I asked if we should plug those and drill two holes on either side of the stringer along the lowest part of the hull to use for if water get under the floor in can get out thru the new holes. If you look at the pic above you will see how high the hole was in it for it to weep into the bilge and it never got all the water out so that's why the boat rotted out, I'm just worried about when you rinse the boat water will run thru the new weep holes and under the floor and stay there. Sorry if I sound dumb as like I have said I don't know anything about boat's and this is all new for me.

Ok, if the transom checks out good then replace the stringer and deck and call it good. I don't like to use dimensional lumber for stringers but if that's what you want to do then go for it. If you have a table saw it's very easy to use 1/2" plywood and make a a 1" stringer by laminating two pieces of the 1/2" plywood together and it will be much stronger than the dimensional lumber. Here's a "Poor" drawing to illustrate how I would fabricate the stringer and the bilge with the drain.
