Hi guys. I posted a thread a few days ago about restoring my 23' Raven and got a few replies within a few hours. I have had this boat for about ten years and decided that we needed to replace the soft floor a week ago. Got the floor up and the stringers are rotting. Started in on the stringers and the transom is "wicked" with water. My wife and I are determined to make the boat better than it was when it was new and it's a nasty, time consuming job but we can handle it with some advice. The way I look at this, there are two (maybe three) ways to do this job. I'm not sure what's best so I thought I would post my thoughts on it and see what everyone thinks. Here is what I think.
Senario #1: All the stringers are pretty much rotten and the ones that aren't are wet. The transom is also wet because the didn't get the whole thing glassed when the boat was assembled so any time there was water standing inside the bilge, a 4"X8" piece of transom was soaking in river water. The rest of it seems like it may be shot to so I'm going to replace the whole transom. Anyway, I say cut the stringers at the bottom where they meet the inside of the hull and reconstruct them with new top notch marine grade wood and glass them back in to the hull making sure they are completely sealed. I would replace the transome first of course by cutting the glass on the inside, removing the old wood. Replace the wood and glass it back in again. It's an odd shaped transome so splitting the top and bottom and digging it out doesn't seem like it will work
Senario two: Cut the tops of the stringers and dig out the rotted and/or wet wood, cut what needs to be cut at the rear in order to replace the transom. Then slide new marine grade wood cut to fit into the old glass stringer molds that are still originaly fastened to the bottom of the hull and re-rap in glass to seal and strengthen everything before I put the new floor in. I figure if I where to add reinforcing side stringers that overlap the pieces that I cut and replaced and fasten them with stainless screws, then glass over the new wood for strength and to seal everything, that would probably also work.

I think cutting the old stringers out flush at the floor, then rebuild them with all new materials is best for the long run but will be the most work. I had planned on posting some pics and maybe even making a diagram but to be honest, It's been a long day and I'm ready for a drink right now (it's Friday) but I have been reading a lot of posts and everyone here seems very helpfull and "has a handle" on the more serious boat repairs. I have no idea what would be best and both methods would probably work but I would like to see what everyones thoughts are. Thanks guys, I'm looking forward to any replies. I hope I didn't ramble on too long.

Re: Raven Countach rotten stringers and transom

I have experienced this torture!!! You are in for it. Definitely remove in their entirety. Try to remove whole so you have a pattern to follow for your new wood. This is extremely tricky. If you don?t have a pattern you will be working forever to get them tight against the fiberglass. It is drinking time, enjoy throwing a few back tonight because you?ll be starting your once a lifetime stringer replacemtn soon. I don?t mind replacing floors, I?ve done three, but only stringers once. In fact, I will throw one back right now on your behalf. Have fun and good luck.

Re: Raven Countach rotten stringers and transom

im a big fan of cutting the whole sha bang out and re glassing the works....

digging out rotten wood from between two walls of glass does not sound like fun.......


forget the marine grade ply....if you have time and the means to dry pt ply properly..i like that stuff....

if you cant spent the time to dry it properly....ext grade is just fine....and will work well for longer than you own the boat.

as for cutting the stringers with out a template......read all of the hull extension...it covers it fully.....so dont worry about that part.....


may i suggest reading....the basic safety equipment for grinding and glassing.
also....tyvec coveralls are a blessing......

were here for ya

Re: Raven Countach rotten stringers and transom

I'm going to try (real hard) to pull what's left of the stringers out in one piece so I have a pattern to make new just as you said. I think it's gonna be pretty time consuming but it's the only way I can see doing it without having it turn into a "measure once cut seven times" job. This whole thing started last Sunday with a soft spot in the floor, now it's complete reconstuctive sugery. You know, I used to drink because I enjoyed it but now it's purely due to stress and agravation. While you guys are in your boats on your local rivers and lakes, I'll be knee deep in fiberglass. I can amagine how envious you must be.
...and Oops, why you are just crazy. Where did you ever come up with an idea to extend your hull? I have already read a lot of your posts and what you are doing is realy impressive. I have been around and worked on boats most of my life (mostly mechanical and cosmetic stuff) but I never thought that a hull extension would have been possible on a glass boat. When I first saw the under side of my boat I thought to myself the last trip in this boat will be to the scrap yard, but after reading what you are doing I figure I have it pretty easy. Checking out your step by step is like a drama and documentury all rolled into one. "Monster Garage" meets "Days of Our Lives". Keep it up and thanks for being so thourough, I have already picked up a few things from your posts. I can't wait to see what it looks like when your done.

Re: Raven Countach rotten stringers and transom

I have replaced the stringers and transom on a Raven Countach. It was a lot of work but well worth the effort. If you plan on doing the stringers its best to cut them flush with the inside of the hull.( a fien saw works well). What I did after making the stringers, was coat them in epoxy, let them dry then scuffed them with a 36 grit disk. I laminated the stringers with multipal layers of bi-axial cloth. I did the swim platform and transom from the outside. Believe me it much easier this way. All of the laminating was done with west system epoxy. I used "Gunk" brand filler to bed the stringers. If you have a good color eye, matching th gelcoat isn't too difficult.
Good Luck RichardC08
