What is this rope and tackle for?

[stuartwineberg]

This was on the boat. The owners notes mention a handy billy but I am pretty sure this isn’t one. It’s heavy duty. To give you an idea of scale the rope is 18mm. It’s a 36 foot 8 ton boat

Could it has been an old mainsheet thats now a "handy billy" ?

One third of a "handy billy" perhaps
Missing another double block and a long rope the right size to fit through the blocks.

A handy Billy is a double block and a single block with a becket, rigged to give a 3:1 purchase. Or two double blocks to give 4:1.
Rope tails or similar allow the purchase to be used in a variety of situations usually by attaching to a rope with a rolling hitch.

A handy billy for lifting the engine out. Keep it safe as you might need it one day. Use it between the fork lift and the engine . Just need to find the lower block and rope.

Thanks all, as I thought a useful but incomplete gadget

 

[lustyd]

not necessarily incomplete, it's quite likely the other block is just in use on the boat somewhere and can be temporarily borrowed as needed.

You might use it a gybe preventer in some fashion if no other solution found

I suspect it might be part of a DIY MOB recovery kit.

The short strop goes over the boom and clips on to the snap shackle.

Somewhere on board you should find the other double block with another snapshackle or strop, and a length of 10mm-ish line to complete the purchase .

Thanks, that makes sense

It would make more sense to me if the block was attached to the eye on the other end of the rope.

Exactly ... why is the rope spliced to the same point as the snap shackle ? Makes no sense ... unless intention is to loop rope round something and then back to snap shackle.

Yep, that’s why I think post 11 has it right

Yes - but as MOB recovery - I don't think so ... as we all know - blocks like this turn and lock up too easy - making a MOB system fail too easily. I think its more likely engine or other heavy weight lifter utilising boom ....

Am just going through all my lockers to remove workshop type tools and "might be useful" materials now that I have storage space ashore. I found two handy billies fully rigged, 1 x 4 part and 1 x 2 part, but had not used them in the twelve years with this boat. When I had to lift the engine to replace the rubber mounts I could have used the boat's gear, but instead made a wood gantry and bought a chain pulley set as it gave me far more fine control.
