Has anyone had a problem with the compression post moving up and down when you put on the back stay? Ours is so bad that there is a bump on the hull forward of the keel where the filler under the compression post is in contact with the hull. What is the fix for this?

I've never observed any deflection on my boat, but to be honest, I've never looked for it either. How much movement are you observing? 1/4" , 1/2"? To my recollection, the port bulkhead is notched into the compression post. Is it deflecting also? When I purchased my boat it had damage to the fiberglass at the mast step. There is plywood sandwiched into the deck at this fitting. If that plywood rots or fails in some way it could I think weaken the whole structure in compression like you are describing. I'd scrutinize this area also while you are investigating the problem. You are aware of the "hidden" bilge? There are threads on this site discussing this issue. I think I've read that neglect of the bilge can cause deterioration of the wood fillers in the bilge. Don't know what the best fix for that is if it is your problem. I heard that one Owner removed his inside liner to deal with some issues, never heard if he got it back together again. That's all I can think of. Good luck.

Joe,

Thanks for the reply. I was the one pulling the backstay, at the dock with no sails, the owner was looking at the post. From his description it was around an inch. The bump on the outside of the hull is about a 1/4". From the access hole cut for the speedo I have felt the compression post base, it is still solid. We were drilled the hole in the cabin sole through the second bilge as recommend but it looks like we did this too late in the boats life. We also have had big problems with the keel hull joint. If the keel has any load on it when we putting the boat on the trailer the joint cracks. Most times starting at the keel and extending up the hull... My guess is the hull has weakened over time. Right now the biggest concern is compression post area. I have been looking on line for a recommend fix but have found none were the hull is failing.

I'll take a look at ours next time I'm out at the boat. Don't recall anything looking strange up there.

Anybody have any photos of how to access this hidden bilge? I want to make sure we drill a hole in the right place. I cringe anytime I have to put a hole in the boat.

1. You all ready have a hole in YOUR boat, pull the keel bolt board, it in the rear lip and you can see down in this area.

2. You can call me and I would be happy to explain how to get the water out, I assume your on the hoist, if not I have a fix for this area, total cost will be 200.00.

Attached are pictures of my "hidden" bilge access solution.
When I want to clear water from the bilge, I just move the crew to the stern and sponge out the water. I generally check the bilge every two weeks but only rarely do I find water. I suspect that rain is the principal source blowing through the hatchway or deck fittings that are leaking. Overall my boat is pretty dry and I live in a pretty moist area.

Got it. Thought that was what that hole was for but I want to be sure. Not on the hoist.

Dad thinks he has the hoist repaired but Mom's Laser 28 will go on it.

PS. Volare did well last year. Got 1st place Spring and Fall series. Field of 12 boats.

I put my hand down the access hole for the speedo and made a closer inspection. I could fell cracks and missing filler around and under the wood block that the compression post sit on. with over 8000 pound of force pushing down on the compression post, a compromised base may be why there is a bump froward of the keel.

I am still look for advice on a fix.

The pictures of the 'hidden bilge' area are on the thread http://catalina-capri-25s.org/forum/topic.asp?TOPIC_ID=20751 A couple of them show some of the area under the compression post.
