Pacific 22 List

Hi there I have a Pac 22 that lists heavily to starboard the trim fin on the leg doesn't seem to help much

. My friend has the same boat old spice. That has no list at all when. At full speed

Any suggestions? Cheers Adam

Do you mean list as in the starboard tube sits lower than the port tube?

Or do you mean if you set the drive leg straight the boat steers to the right?

Better / worse at speed?

Old Spice had a major refit, an uprated engine, new console and fuel tank etc, IIRC.

Sorry what I mean is when on the plain the boat leans on its starboard side due to the rotation of the propeller. To the extent that it takes a person sat on the port tube to level the boat. This make the boat hard work when on my own.

I understand old spice is different but I can't see any port side ballasting or hull diffrances apart from two aluminium rails screwed along the rear section of hull and that has no lean at all.

Cheers Adam

Hopefully some of the other Pac22 guys will be along to comment on how common the issue is, and how they deal with it. The obvious solutions to me are can you move batteries, spare fuel tank or even anchor chain so that they are stored off centre to balance it out.

One source of leaning is the propeller, difference props has different tendency to do this.
Another thing that come to my mind is water in the hull, is that possibility totally excluded?

Was Old Spice rebuilt with the leg offset slightly to counteract the prop torque - or does it have trim tabs fitted to stop it?

I've just looked back through the Gallery - Old Spice has got much more kit on that yours - A-frame, various racks, heavier/larger console (containing more kit?), so could be quite a bit heavier. If her tubes are in the water when she's at speed, then that might reduce the tilt - if yours is riding higher in the water, then just becasue you get less effect from the tubes, you could get more tilt.

I can't think of anything else if both boats are identically kitted out, and they don't list when at rest.

Adam, I used to own Old Spice. First thought is it the trim you are using on the leg. If yours is lighter and you have the drive trimmed out then she will be running on the large planing pad and could then lean over from the prop torque. Stick some weight on it by using plastic drums with water, especially up the front. 200 litres wouldn't be too much. Remember Old Spice has a big fuel tank under the deck.

Next the prop, are you sure no one has previously fiddled with it, changing the pitch and cupping. I had several props on Old Spice which were different sizes, however, overall the standard 16.25x21 (I think) gave the best all round performance.

Old Spice has a set of speed rails fitted (or did) to give lift at speed to the stern. She certainly ran much more level when then were fitted and there were lots of folk or divers sat on the engine box.

Regards Pete

Thanks Pete I will play around with balasting I have tested the boat with a new lancing prop and the list was even more apparent

Old spice still has the rails and trim tabs aswell which seem help a lot with heavy loads
Cheers Adam
