Good point. I plan on having a line between me and the mast. Maybe that would be some insurance.
My rigger friends say that the 150 lb guy can let go completely of the line and with two ratchets engaged they will hold him. The 200 lb guy will sink but not too fast.
But I see your point the ratchets are a help not the thing.
If you want to go this route I would suggest two things:
- A cleated pully (on the bottom end, not the top ). The cleat allows a firmer 'lock' then just a ratchet.
- A pillowcase or other such bag to accumulate the line you have as you pull yourself up. It would be suspended between your legs so you can reach it and detangle yourself....
the danger with not having a bag, is that the lump of line on the deck CAN get tangled on something as you try to get down... and ... it is quite difficult to detangle if you are alone.
I have been hauled up using the halyard with an assist from a friend using the power winches.
I have used the ratchet method to do it myself.
I prefer the 'control' of being self reliant, rather then trying to yell to a person on the deck that they have to stop as I am tangled in something on the mast...
Best of Luck regardless...
