Hey all:

My boat, an '83 FK SR Catalina 25, has developed a mysterious slight list to port. I first noticed it in the first sail this April - upon leaving the boat I saw that the mast was slightly of kilter a few degrees, only noticeable among the background forest of other masts that were straight up.

But then I have noticed that the whole boat seems to be listing a touch. This was not present last summer when I bought the boat and sailed. The mast has been down and back up once since then.

At first I thought it was merely because the water tank was emptied for the winter, but then so was the holding tank. Then I thought it had something to do with the engine coming off for service, and the battery coming home for recharging (both on starboard) but the list remained when they came back aboard.

I find no leaks anywhere, and list does not seem to be getting worse.

The bilge has always been very dry, and though there is some evidence of past water, the bolts and nuts are not at all corroded.

She sails as she always has. The bottom cleaner just came and reported that all looks good down below the waterline.

Ideas? Suggestions? Make sure my insurance is paid up? (ha ha)

Thanks in advance,

Carlos

Is it noticable at the waterline? Perhaps it's just the mast not in column from the take down and re-rigging.

I hadn't thought of looking at the waterline. Good idea - I will be at the boat in a few days and will check that.

I haven't yet measured the shrouds, but there is no reason to think the mast itself is leaning off to one side. It's still in column and has no bends. But I'll check the shroud lengths as well.

The mast being a little off can have a big impact since it's a 30' lever. Your turnbuckles should screwed in approximately the same amount as a quick check. Run a 50' tape up with the the main halyard and measure to the bottom of the each turnbuckle to verify that you are actually out of column. If you don't have a 50' tape, mark your halyard with tape and swing it across, mark the shrouds with tape and measure from there to the bottom. There will be a slight variation since the halyard doesn't come off the center, but it shouldn't be significant. You can also hang a heavily weighted plumb line from the halyard, but that requires that the boat has no list. The cockpit sole and base of the companionway should be level athwartship if you are centered to read a carpenter's level.

Take a halyard and use it as a rough measuring device to compare the distance between the masthead and the chainplates on each side.

I centered the mast when I tuned the rig last spring. It may have fallen off a bit, and like I said I'll check it when I see the boat again. That may be all that it is - just a little bit of lean is pulling the boat over a tad.

Here's a pic of the mast:

I juxtaposed it right behind another mast to show the tilt.

Are you sure your holding tank is empty. We get strange lists when we go on trips starting with a full water tank and an empty holding tank...to Starboard. Then returning with an empty water tank and a "fuller" holding tank...to Port.

Davy - That's what I thought was going on. I drained the tank for winter and put in maybe a gallon of antifreeze and pumped some through. That's my next step - is to fill up the tank. Were the boats designed for the motor, battery, and full water tank in order to sit up properly?

Have you cleaned out your dumpster lately? I was shocked how much gear it will eat

Justin:

Ha ha ha. Actually, you might have a point there. I did put some stuff in it that wasn't there before. I didn't think it would make a difference weight-wise but it might be contributing. Good comment.

Put a board across your cockpit seats or coamings and put a carpenter's level on it to determine whether your list is in the rig or the whole boat. If the boat is level, then all you need to measure the rig is a weight on a halyard, hanging free. If the hull is listing, then the pulling the halyard to the chainplates can show whether the rig is vertical relative to the hull.

However, many C-25s list a couple of degrees to one side or the other--I think more to port, probably because of the "furniture" down below and the contents of the "dumpster." The C-25 is a relatively narrow hull, more prone to a slight list. Whatever tiny amount of speed you lose from that on a starboard tack you'll make up on port.

I purchased my C25 new and didn't notice a slight list to port during the test sail until I got it on my mooring at home. It's an 1988 traditonal model, flat floor, battery box amidship, holding tank in the bow, and water tank under the starboard setee. Couldn't figure it out so I always kept the water tank full, which minimized the list. A discussion on this forum solved my problem. On pre-88's with the battery box and water tank under the starboard setee, the motor was mounted on the port side. Which is where the dealer mounted mine. On 1988 and newer models, with batteries amidships, the motor had to be on starboard. I had it moved and she sits with only a barely noticable list to port. If I hadn't removed my water tank for storage there wouldn't be any list at all.

My boat sits level after the water tank is filled to the top.

To check the boat's attitude, place a level across the cockpit seats.

Us too...our OB is port side, we fill the starboard side water tank (also add 3 - 4 oz chlorine bleach) and the list to port is pretty much gone...battery and lunch hook are also starboard side...

My OB is starboard side....battery bank and water tank are under starboard settee....waste tank is under port settee. I only notice a list to starboard when I'm sitting on the starboard side....but it will change to port when I sit on the port side...both times very, very slight. I've looked carefully at her when slipped and I'm standing on the dock, and she looks perfectly level to me.
