Your underbody is very similar to my ‘99 Bavaria 38E, but mine with a six-ft draft. So, I expect similar dynamics w.r.t. heaving-to. Basically, my boat does not heave-to very well at all. Tends to “pivot” against the narrow keel. A wider keel as in the older Cal yachts works much better.How well does a Beneteau 373 with a shallow draft heave-to in heavy weather? Say Beaufort 6 -7 or waves that roughly match the beam of the ship
