How strong a halyard for MOB retrieval?

This thread got me thinking about all the gear we have on board for our short handed coastal cruising. I just added an 8:1 handy billy from Jimmy Green (currently on offer) and will store it pre-extended in a bag on the basis that prepping it by pulling the 8x line through might take some time!

Does it have a jammer / clutch because taking the load continuously even 50Kg might not be acceptable / possible.

Yes she could lift the liferaft but it's position meant that by cutting the guardline lashings it could easily be launched into the water either side of the boat, something that was at the forefront of thinking when determining its position.
As I said I know how difficult entering a liferaft alone can be having done it ( in practice) but it seemed the best option and one I even now can't think of a better one. A dinghy would be an improvement especially with a partially inflated tube but when underway our dinghy was always deflated and stowed never towed. A sugar scoop stern would also be useful but again our yachts never had one.

Yes for those of us who have a dinghy ready inflated and easily launched, I think it is worth considering this option, especially whilst crew remains conscious and moving. Still not easy to get into a dinghy (lacks liferaft ladder) but low freeboard and good incentive on casualty to get into dinghy.

Yes, "Cam Cleat to grip line" although I was thinking of asking them to fit the Barton Skylock I saw demo'd at the boat show. The 800 is rated at 475kg.

My 8.1 has a ratchet block which you can switch on off. However, the ratchet is at the top, so not available to adjust.

I weigh 92kg, my partner is 55kg. My partner can lift me onboard easily with one hand. The ratchet block allows the line to be pinched under a knee, while the pulling hand is slid up. The ratchet block also allows the casualty to be lowered by letting the line slip back through the ratchet sheave.

Tip
Set it up so that it does not need to be adjusted, as you are planning. Mark the preferred halyard, that you will hoist the 8:1 on, where it should stop. Not really required as the length of the 8:1 line is preset, but it does help, in case there is an issue. I just used a sharpie pen to make a black band.

I keep mine in an old flare tub, both carabiners on top, marked with sail cloth strips, “halyard”, “MOB” to avoid confusion. When bought, mine came with thin nylon strips, 2” wide, an about 2’ long, that tie the falls together below each block, simple slip type bow. That stops the block from inverting through the falls when handled. Easy to remove on the day.

Even just hanging onto the side of it will give the casualty a much better feeling than being supported only by their lifejacket.

IF the lines along the dinghy are securely fitted.

One of my lines decided to unravel all by themselves last weekend. On Friday I will be replacing them with some decent locking slices and sewing them just to make sure they are truly locked.
 
I was chatting to the guys at Barton Marine today about their "Sky Lock" (see my post #122 above).

They suggested I look at the "Catch & Lift MOB System" that uses a sea anchor and the power of the vessels engine to recover an MOB. I believe they sell their blocks for this product.

CATCH and LIFT MOB Rescue System

Not convinced myself but the concept is good.
