Does your hull give?

Hello sailors, I was at the boat (73 Catalina 22 #2113) today looking around the cabin for a good place to put my nav station. When I noticed that in the storage compartment under the aft seat at the table, the hull looked convex. I put my hand on the hull and pushed to find it had some give to it. I checked other areas of the hull (under storage compartments) and they where not as “soft” as the area under the aft dinette seat. Is this normal? What do you make of this? Is your hull the same way? Please let me know what you think of this situation.

Doesn't sound normal

I'm relatively new to this sport, but my 1984 C22 doesn't do that. It doesn't sound normal to me.

I don't like that either

My C-22 #9911 built in the later half of 1981 as a 1982 model year does not give in that area as yours. As you have a fairly old boat, this may be a trait your particualr C-22; however, this is just speculation on my part as I have no specific information. I wonder if your condition may be caused by resting on a roller trailer of boat stand for an excessive time.

what does it look or feel like on the outside

of the hull. it should feel the same of course, but do you see anything in that area on the outside???? I have a 74 and know exactly where your talking, if you have it on a trailer that puts it pretty close to where the middle of the bunk on the trailer is...i'd look on the outside tho..maybe a hairline crack on the outside which you cant see from the inside.... hey, not there. soo just a guess

Canning?

Might be the result of canning (sp?)...basically what happens when a lot of boat weight rests on a relatively narrow portion of the hull, instead of being evenly spread out. Unfortunately, I have the same situation. I got back from 10 months away a couple of weeks ago and found that, over that time, some canning has resulted at the back of the trailer bunk (port aft). What I'm doing short term is jacking the boat up and putting wooden blocking/shoring along the bunks to more evenly distribute the weight. I do know that soft spots in the hull are not good. However, like you, I'm going to have dig through some books and this bulletin board to figure out how bad the canning has to be to worry about, and what needs to be done to fix possible damage. I do know the general common sense bit which says that soft spots are bad, soft spots below the waterline are worse. Hopefully someone with some more experience posts here... Scott

more questions and opinons

I think, like others, it may be related to a "storage" condition like a bunk board or roller sometime durring its life. Due to the lack of internal support ie.bulkhead, my boat, a '76 swing, developed a reverse buldge, or dent because the bunk board bolt had slipped, in the middle, and put too much stress under the port stearn. I adjusted the bunk and replaced the rusted bolt and alas the buldge returned to 90% of its original shape on its own. If the fiberglass on your hull is sound (hard, dry, and no cracks), and the movement is just because it no longer matches the curve of the hull, you may not have a structural problem. If, however, the fiberglass is comprimised like open fibers or moisture absorbing then it must be addressed. Anybody that has spend the money and effort to "fair" their hull wouldn't like it but a small dent probably won't slow it down too much.

No trailer involved

I bought the boat about a year ago from a gentleman who lives in a house that is backed to the water. He said the trailer rusted away years ago and never replaced it. So the boat was permanently in the water behind his house. The water is a channel that leads to Lake Pontchartrain. About six months before I purchased the boat he had it hauled out to do the bottom and replace the keel pin. So I have the boat moored at the harbor with no trailer for it. So I do not think that the condition in that area of the hull is from sitting on rollers of the trailer. Because it has been many years since that boat saw a trailer. Having a trailer and a truck for the boat is a luxury. As far as weight distribution, there is nothing onboard the boat to add much weight to it other than a battery, gas tank, pfd’s, radio, and ice chest. There are not a lot of supplies and clutter onboard and most storage areas are empty. I am not familiar with “canning’ but I will look into it. In the meantime, I plan on bringing the boat to the shallow area of the lake. There I will go overboard and inspect the underside and keel. I have also though of making a brace or support contoured to that area and fiber glassing it in place. As a last resort there is the option of hauling it out and redoing the bottom and reglassing it with supports. But that is costly, the haul out and storage part. If there is anyone in the New Orleans area with a trailer for a C22, and would like to help a fellow sailor out, I would rent a truck and bring it to my house and work on the bottom there. Thanks for all the responses, I was just wondering if anyone had or fixed the same problem. 73’ Catalina 22 #2113 Have a great independence day, Rick

Ask an Expert

I had questions about my swing keel. A different issue entirely but sent an e mail directly to Catalina (robertbutler@catalinayachts.com) and received very helpful advice. It may or may not be serious. For example, on my old Hunter 19.5, the entire hull aft of the wing keel could be flexed quite easily, which I discovered accidentially one day when applying bottom paint. This did not seem right to me and I contacted Hunter. I was told that this section of the hull, when manufactured, did not have as many layers of fiberglass as other parts of the hull, which must deal with greater stress. My C-22 is on the trailer in the yard right now, however, and I am unable to find any spot in the hull which flexes from underneath the boat. I'd ask the experts and go from there. Someone might be willing to borrow you their trailer so you can get it out of the water for a look.

south coast 22 owner can relate

6 mos ago I purchased a south coast 22 in the water, no trailer. on further inspection (after the purchase) I found a huge soft spot on bottom, with symptoms the cat-22 owner describes. I heeled the boat over till the swing keel showed, and after many many barnacles found a one-foot by half patch, which must have weakened the super-structure, thus creating an indention after the boat was trailered for a length of time. This small trampoline has no place on a daysailer, so I reinforced it with a criss-cross of small bulkheads. Selling it, but she's been a fine boat for the shallow Indian River(10"to5" draft).
