Passing motor boats are a nightmare when racing. Hero to zero if they catch you wrong.
Agreed. The key is in the term "semi-displacement". Perhaps the term should be "semi-planing". Even at speeds of 20 knots or so, the bow is tipped up and they are pushing a great quantity of water aside. This is very different from the light speed boat, which seems to skim the water leaving little wake at all. As a dinghy cruiser, I have become adept at recognising the former in time to alter course to cross their wake on my bow, as it risks swamping or even capsize (perish the thought!) to meet such steep, closely spaced waves on any other bearing. I fly Romeo Yankee from the spreaders when there is much traffic about, but it does little good - most of them seem a bit rusty on the International Code of Signals.Big difference between a heavy semi-displacement hull like a lifeboat and a light planing speedboat hull. The latter will generate less wash at high speed than slow, but the opposite is the case with the former.
