Just adding my 2 cents as well. Might not even be worth 2 cents in this economy.

I believe the best course of action when dealing with heavy weather is to sit back, relax and wait for a better day. When you weigh the pros and cons of running in weather, the cons are often just too great.

With that being said, ship stability is really a pretty fascinating subject. Whole courses of study are devoted to the topic at maritime institutions. As far as our M's go, when running downwind it is important to stay "ahead" of the waves. If you slow too much and the waves overtake your vessel, you run the risk of being pooped (yes, an actual term) or broaching. This risk is greater with our M's because of light weight and small (TOO SMALL) rudders. In my opinion, a little speed is a good thing in heavy weather. Also, keep in mind that trim tabs are a tool to assist and should never be relied upon to correct a loading or stability problem.

But, take heart, I have never heard of an M rolling over in bad weather. Not to say that it hasn't happened, but maybe it is more a reflection of good judgement on the part of the captains.

Be Safe,
Scott
