1979 Bayliner classic 2452

[tomturner]

My friend bought a 1979 Bayliner Classic 2452 last summer and used it with no problems.
We put it inside for the winter to do some repairs and upgrades. During our inspection we found some rotted plywood in some of the bulkheads, so we started to remove them to be replaced. After pulling the motor and leg, further inspection showed that the wood in the stringers was also rotten. Is there a way to repair these?
Some thoughts we had were to remove them completely and replace with Aluminum tubing, or to cap them with aluminum u-channel bolted and epoxied to the still sound fibreglass.

Pic would defiantly help. I do not recommend trying to cobble up a stringer with aluminum. If they are bad you need to cut out and replace with like material. Do a search and you will find many articles about this. Dont mean to sound crude but your life and everyones life in that boat depend on those repairs. Look for opps and the hull extension thread it will show a lot of the information you need. Just dont cut your boat in half Opps is crazy like that.

Hello Tom and welcome to Iboats..

Well I guess you Could gut and frame your stringers with alum..but Im thinking your trans is toasted too..

So how do you Robo-cop alum your frame/trans in.. ? hmm..never did it..

Im sure it can be done with alum...but your cost vs weight/integrity could be comprimised.

Your kinda wanting to reinvent the mouse trap.. Im Sure Positive that it can be done..but with Most its just not cost effective. AND Im sure nobody has put an alum substructure in there boats this way ( not production wise anyway ).

If you like you can give us a bit more info with pics could help out..

YD.

Thank for your replies I have visited oops thread and found it very helpful. I will try to get some pics soon, but they will not show much. The glass on them looks fine, but the wood inside is rotted, which we found while removing the bulkheads and the plywood from the transom ( you're right it was also rotten, but that is an easy fix). we havent opened the stringers except enough to confirm their condition. We are hoping that they are not rotted for the full length, so we will not have to remove the cabin. We don't want to do too much cutting until we have some sort of plan. Hope this post winds up in the right place as this forum thing is new to me.

Re: 1979 Bayliner classic 2452

It will probably all have to come out, new stringers and transom.
The mental resistance is harder than the actual work.

Re: 1979 Bayliner classic 2452

We have come up with with another question. The wood in these stringers is onlyabout 1 1/2"x2". The glass on the outside is 3/8 " thick. Is it possible that the wood was only used as a form to glass over? To my untrained eye such a small peice of wood cant contribute very much strength.

Here are the pictures that i have been trying to get .

Greetings!

I am far from boat expert (or anything expert for that matter), but I would say, while the wood is probably there for form, it is also very likely providing quite a bit more strength than you might think. Thin layers of moderately strong material bonded closely together support one another. Leaving a hole in the middle (or allowing one to fully form) is just asking for it to crack in my humble opinion and that could be disastrous.

Respectfully,

Re: 1979 Bayliner classic 2452

Motor mounts are trashed..Trans is trashed..Stringers I cant tell from the pics.

A whole lot of rot there.

Buy a Full Face Resporator.

YD.

Re: 1979 Bayliner classic 2452

Thanks for your thoughts. I am thinking about the same thing.

Re: 1979 Bayliner classic 2452

Re: stringers If you look at the picture with the tape measure, the 3 1/2 mark is about the center of the glass on one side and the 4 5/8 is on the other side. Rotted wood is in between. How much structural strength does such a small piece of wood add to that much bulk of fibreglass?

Re: 1979 Bayliner classic 2452

You don't really want to go in there twice do you?
Theres a fair amount of damage visible just from the photos.
Rot spreads, it grows like fungus (because it IS fungus), so it has to come out.
We've all been through this stage.

Re: 1979 Bayliner classic 2452

Sadly the right way to do it is to tear it all out. If the wood's wet at all it's rotting

Got to side with the group do it once , do it right.

Re: 1979 Bayliner classic 2452

Ihave been doing some mor research and have found some alternatives that look interesting. Some of the other forums have sugested drying and stabilizing the rotted wood with penetrating epoxy. and then adding aditional glass layers.
another suggestion was to "sister" new wood to the old and glass over the whole works.
Any thoughts or opinions would be welcome.

I don't think, in fact I'm almost certain, that NO ONE here on iBoats will advise you to do anything other than to remove ALL evidence of rotted wood ANYWHERE in your boat and replace it. Of Course it IS your boat and you CAN do whatever you want, but the voices of experience on here will not always agree with your decisions. They will only tell you what their experiences have taught them to be tried and true solutions to the problems you post.
