My introduction to ribs, a soft transom

Hello. I just bought a rib, couldn't resist. I have always wanted one since being introduced to them in the Coast Guard. It's an 86 avon supersport 4.00, with an 86 Suzuki 40hp. The transom seems soft, the floors need to be rebuilt, glue needs to be redone etc. it's a boat, I will throw money into and overboard. you know how that goes. you guys could tell me more about it I guess. Here are some pics, guide me "o" wise ones. One of the first lessons I have learned... keeping an eye on self inflation due to California heat.

Welcome to rib.net

Is that not a SIB? I assume it is Hypalon so the material is going to be pretty tough, although it looks like a few pieces might need replacement. You definitely have your work cut out for you. Keep us informed as you progress.

What do you plan to use the boat for? Mine is mostly used as a dive boat, and the rest of the time to cruise around the SF bay and the ocean, with an occasional lake thrown into the mix (Tahoe excluded having a two stroke).

Yes, sib. I call them all ribs, I guess now that I joined rib_net, I will improve my nomenclature. I bought the boat to access some tricky hidden surf spots in and around the sonoma coast. I got the boat really cheap, (I realize, there is nothing more expensive than a cheap boat) , but I am capable, and will do all the upgrades, and refit. So far, looks like I need controls and steering for the Suzuki outboard, various rigging, and glue. Anything you guys think I should do, while the motor is off the transom? Peter c, you are local, that's awesome. Hope to see you out there.

I think you meant, anything to do, while the transom is off the boat? I would recommend sanding and resealing it.

Kelson has his SIB set up with a surf board rack on it.

Actually, I did mean while the motor is off the transom. I was going to do some temp fixes, use the boat sparingly this spring and summer. Just to familiarize myself with the boat. Then, in october, (plenty warm for the glue work) do the repairs needed for the upcoming surf season. complete overhaul of the transom. I understand twice as much work, removing the old glue and etc. Peter c, what do you think? I see in another post you did the job in 40 hours. Do you know of a local place to get marine ply? I am thinking Sausalito or somewhere south of me. trying to find it north of Petaluma.

Is the transom soft in that you get flex? Like you have rotting wood in there? If so, that's something you want to address before taking it out. Depending on condition, you may have to completely replace the entire thing, or, if it's localized, you could try one of the "rot stop" products (which are usually an epoxy or other resin that gest injected into the rotting areas.) Bracing everything with stainless or aluminum sheet as a sheath may help as well.

If you have the motor off, take a close look inside the bolt holes; those are a primary means of water ingress.

Mead Clark lumber right behind the auto row in Santa Rosa has marine ply. It is expensive, but there are not a lot of options. You will probably have to glue two pieces of one sheet together, than make a rough cut with a jig saw and finish it using a router with a bearing to copy the old transom.

I would not take the boat out in the ocean without knowing the transom and glue are in excellent condition. As you know our coast is unforgiving, and rescue is often not available.
