Well ... if you are under power, a sailing vessel has one less light than you.

27...I suck

Passed by the skin of my teeth, missed seven but considered a pass. I wish I had the study gouge! But it has been eleven years since my RYA Open Ocean and Offshore Yachtmaster courses. I am minus some serious brain cells.

P.S. I am a trawler crawler now.

Ditto, 36, missing 5 of first 11

a stupid test but an amusing event

Wow!
I hope I can stay alive till lunch

30 the first time, changed a few answers I wasn't sure about, now 39.

WTF with the tugboat, eh? What turned out to be a barge, I thought was an island (the difference would be obvious in reality, not so much on a tiny, overcompressed JPEG). Our tugs around here all push the barge from astern. I also got caught on a few of the knots-and-ropes questions (who ties a rope rode directly to the anchor?).

And, of course, since most of the big-boat manoeuvring stuff is irrelevant to the outboard / sterndrive powered boats I cruise in, I missed a few of those (does it really matter whether you're on the windward or leeward side of the channel?). I know about prop walk and such, in theory- in practice, even though I have enough fully vectored thrust to do thirty knots, "reverse" means "bow will swing downwind no matter what" and springlines are something you tie on once you're docked to keep you from hitting the boat behind you when the wind changes. Swinging the stern out? That's what a crewman with a boathook is for.

Overall? Amusing, perhaps a little helpful, large parts of it not relevant to my kind of boat.

35 with some lucky guesses and tripping on the spring line (probably got it backwards). The answer for Question 21 with the tugboat needed a much better picture to make it a fair question.

And what answer did the quiz want for Q. 36, which part of the body loses most heat? I guessed trunk but it probably should have been legs and I for sure hope they weren't headhunting:

The US Sailing Study guide (Sailing Emergencies) under the Hypothermia heading claims, "Most of the heat loss occurs through the head".
NO!

The course designer seems to have bought into a * myth * based on a misleading US Army study from more than half a century ago. Yes, the scalp has lots of blood vessels that are good at exchanging heat, and with lots of sensitive nerves on the head and face, covering the head makes a huge difference in how warm you feel. But the head, with maybe 10% of the body's surface, would generally lose only something more like 25% or 30% of body heat according to the best sources I've seen so far. And if the head is being held up out of the water by a PFD (lifejacket) while the rest of the body is wet and a person is shivering, the percentage loss from the head would be even smaller.

Sure, I could probably replicate the mis-leading result--just dress someone up in a survival suit minus a hood, hang the person upside down, and dunk his or her head in frigid water! NOT a good idea with an (until-then) live person!

This would be a good opportunity for the course designer to update the class with current information on the effects of cold water immersion, including cold water shock, gasp reflex, and swimming failure, which can kill someone before hypothermia or post-immersion collapse get their turn at bat.

See
Jolie Bookspan, M.Ed, PhD, FAWM: "Losing most of your heat through your head is a popular myth. Head heat loss is not the majority of body heat lost. Not even close" Do You Lose Most Of Your Heat Through Your Head?

Also, the Cold Water Boot Camp (Cold Water Boot Camp ) web site and some of the Sea Kayaking groups (Sea Kayaker, Seakayaker Magazine - The latest seakayaking news and information) have great information on cold water hazards.

THIS! Same score..big gray cruiser...lousy food and smelly crew..

I don't really care what the bloody prop does..my boat has no engine!

Retook the test, did better (by feeding them an answer I consider wrong and another one that the picture didn't enough detail for the right answer), and sent US Sailing a feedback with my comments on a few of the questions. Maybe some day I'll get some feedback from US Sailing that I can share with folks here.
