Wayward lean

[kghowe]

Out and about on Monday and noticed that the boat has a tendency to suddenly heel over to port. Never did it to stb. As the boat is still fairly new to me (320 Sealine Statesman) it was a bit un-nerving. It hapened twice both times whilst at about 22-24 kts accelerating slowly. Conditions were a force 3-4 (ish) beam sea, sea state less than 1 mtr. It felt as if it would of stayed leaning over but I slowed down so as to right it. I've just put a dinghy on the snaps for the first time and wondered if this has unbalanced it or acting as a wind vane? My Targa had a similar tendency but the hull handled differently than the Sealine. When below 20kts it never did it.

Any ideas? Or am I being silly?

I would asume you`ve already tried to adjust the trim tabs,to no avail.So does the vessel have outdrives? If not take a look around the boat and see if you have any particular heavy objects on the port side. I found this on my friends boat just recently where he was carrying 2 very heavy spare props in his lazarette and we moved them to the opposite side of the boat problem solved. Also tanks filled level. If not on some boats if you are going at the top end of the speed scale if not trimmed properly the aft end tries to lift and push the bow over to one side.Are tabs working properly?

If its anything like my old 305, this is a characteristic of the boat. The hull waterline length is relatively short for a flybridge boat and it is very sensitive to weight distribution and trim tab position. With my old boat, if you tabbed down too much, especially over 20knots, the boat would'nt track straight, lean over and even start to 'porpoise' - bounce up and down even on flat water. None of this is dangerous, as far as I know, just disconcerting

Thanks for advice, I have checked trim tabs but will look to see if the wife has sneaked in a wardrobe full of clothes somewhere. We don't tend to load the boat up too much anyway (probably a trait from caravaning days) so I don't think its loading. All heavy stuff is generally along center line. Oh well i'll have to have a play and see what turns up, I'll keep you informed.

Planing boats tend to heal into the sea. It's not a great problem, though you can trim out of it. Trouble is that you finnish up not knowing where the trim is. So could cause problems in the next leg. Suggest triming it out, then reverting to bows up position at next way point, then re triming.

Agree with Deleted User, Sealine 305's 320's, 330's, F33's, all the small outdrive flybridge Sealines seem to do this. If it isn't flat calm you can speand your whole passage with your fingers hovering on the trim tab button correcting one way then the other. Something of a bias in the sea keeping/accomodation compromise me thinks..!
