I have started this thread after asking Thataway a question about how he used his davit to get an MOB back onboard. I hope other C-Dorians will share what they do.
The conversation so far:
MY QUESTION
Bob, I'm researching how to get an unconscious MOB back aboard a C-Dory 25' and was struck by your stating that you practiced with your dinghy hoist. My husband and his wet clothes would weigh about 225 lbs if he were the MOB. If unconscious, he would need to be winched aboard somehow and a dinghy davit seems to be the only way to do this.
So... many questions: Where was the base mounted on the boat How much did the boat heel when you were lifting and swinging aboard the MOB? Can the MOB be swung into the cockpit? Could you have attached a "net" to the davit arm so that you could lift the MOB horizontally (to prevent circum rescue collapse)?

ROBHWA's RESPONSE
Fellow C-Dorians; Bringing a "dead-weight" (i.e. can't help in their rescue) heavier person over a ledge is a common problem practiced and unfortunately sometimes done in mountaineering rescue. I had the opportunity many years ago to participate in such a rescue on Mt Rainier. Approaching it with a fiberglass "ledge" on a C-Dory poses a similar problem to bringing the person over the edge of the crevasse. I also recently helped pull a 170 lb halibut into a boat, not a C-Dory but with similar relatively low gunwales. One person tried but couldn't lift into the boat themselves. 2 people couldn't easily either. I was surprised that it took three people to wrest it over the side. Basically, you're going to need "mechanical advantage" with a pulley system and a firm place to anchor it. I've practiced doing this with 250 lb people over the edge of crevasses using a 3:1 mechanical advantage "Z-system". Not easy but doable if you place a pack at the edge of the crevasse so the rope doesn't dig in. You are able to use your legs, which might not be easy on the boat. I wonder if such a system might be adapted to rescue on a C-Dory? The crux of the problem is probably bringing the person over the gunwales of the boat. Has anyone tried this in real life?
