Some Options
The original poster said "open water", but also contrasted the question with "at anchor", so, this depends on how 'open' open water is (at least not an anchorage).One place to hide is in the lee of land, such as an island. I once got caught in a gale off Catalina Island in a chartered Catalina 34, Cat harbor reported 35kts wind. But, it was not that bad because the island protected us from any big waves. We just motored, always keeping an eye on sailing options just in case the iron genny died.On lakes here, I have also hove too under power with no sail up while a thunderstorm rolled through. Small lakes have small waves, so the outboard was not at risk of flooding or the prop coming out of the water. We used the motor to hold position with the bow just a comfortable amount off the eye of the wind. Motoring can be a good storm tactic as long as you have a plan in case the power dies.These are far from the only good options. What to do in a storm will depend on the boat, conditions where you are, and how many options that you have prepared for in advance. The more options planned and practiced in advance in less dire weather, the better.OC
