? too short to be part of a purchase-providing system for getting up the mast ?@ Puget sailor - If you don't mind me piggy-backing on your menagerie of curiosities, I'd like to post this picture of tackle which came with our boat. The previous owner was of 'diminished capacity' and his family didn't know what it was for. It's stumped everyone who's seen it. I roughly estimate 125' of line, maybe more.

Any ideas, folks? A little puzzle to go with your Friday cocktail.
Remember that the carabiner has to clip onto the harness of the MOB person at water level, and the top set of blocks will be clipped to the end of a secured halyard that is likely 4 or 5 feet above the deck, because there has to be room to hoist the person up without 'two blocking" the two sets of double blocks, when you winch the person up with the line that you have led to a primary winch. Counting the end of the line led to the winch you might easily have 50' of line in motion, and you want some extra for the tail to haul on. The original owner may have bought more line than was really needed, but that's not as unpleasant as it being too short, when used in an emergency.? too short to be part of a purchase-providing system for getting up the mast ?
I finally had time to stretch that tackle out and it is 65' long!!! Not the rope, but the 5:1 tackle extended (325' of rope?). I keep coming back to having shorter tackle. There's no place to stow it convenient to the cockpit, the bundle is too heavy for some of our crew to manage, and it's a tangle to deploy. The Lifesling brand kit is 3:1 and about 21' long laid out. If my math is right, that's about 15' of lift with 20' of bitter end. We've got a tackle with a cam cleat that I use off the boom for the outboard. Seems to me that would work for this as well. Is there a compelling reason not to have the camcleat? Or a ratchet block, perhaps?Yep, it's probably a COB retrieval gear. I've been through the Safety At Sea seminar a couple times. They talked about COB, probably with slides. The last one included a morning session in a pool, with PFD's and foulies. We climbed into life rafts, and other stuff, but I don't remember practicing retrieval with tackle. A hole in the course to be addressed, methinks. (or a hole in my memory) Once Donna and I get our boat going (very close!) I want to gather a few friends and actually practice COB procedures. Until then, I'm just working on theoretical geometry and PowerPoint presentations. Regarding Christian’s sage advice of staying on the boat, we do have jack lines and harnesses, we’re getting our ancient lifelines replaced any day now, and we take other precautions.

Can it be used as a solo mast climbing contraption?I finally had time to stretch that tackle out and it is 65' long!!! Not the rope, but the 5:1 tackle extended (325' of rope?).

That's a thought! Though, heaven forbid you let go of the working end.Can it be used as a solo mast climbing contraption?
yup - that was my thought too (back at post#23)Can it be used as a solo mast climbing contraption?
I had dismissed that as too dangerous then just this morning I was looking through a past issue of Cruising World and saw someone using something similar.yup - that was my thought too (back at post#23)
