Pac 22 tilting to starboard

Hi All
Going down Southampton water towards the docks, my boat was leaning to stb. as we went flat out!! (not that fast) not turning to stb. but down on the stb. side. has anybody got any suggestions.
Thank you

Had my Atlantic 21 do this, I had one side under deck with a blocked runaway , pain in the ass it was,
Hopefully you have access under deck near the front just check no water is held in the compartments shown on pic

These little conduit drains get delaminated wood glass in them more often than you would expect on these old craft, hopefully a simple cure ?

Thanks for the advise,
I will check that out today.

When I had my P22 it did exactly the same at WOT. It seems most of them did it. Once I eased back on the throttle it straightened up. There was a thread on here years ago about this....think it was something to do with torque caused by the prop.

My Pac 22 with the Hamilton Jet fitted doesn't lean, but is quite flighty at WOT. A lot of this is down to the jet nozzle having a passive hydraulic system controlling the nozzle which is like having play in the system. I will probably convert it to cable over the winter. I have trim tabs that help with this to a point and then make it worse if too much trim is put on.
I also agree with checking the side chambers for water, it has quite a complicated series of drainage systems that if blocked would mean you could effectively carry probably 100 + litres of water per chamber?

On re reading this, if it only leans on WOT and sits level at rest, it is unlikely to be a flooded tank. They do have an enormous prop as standard and it is more likely to be a torque reaction. Fitting a trim tab might help?

Thank you all for your replies, its been very helpful

I've had this on my little tornado... Was the torque from the prop. a wee tweak of the helm when coming off a wave sorts it out, or not trimming down so far also helps. I find it a bit difficult to get the sweet spot on the trim... low enough to keep the bow down, but high enough to stop the lean!
