Related to boats as it is for my dinghy... but wondered if anyone can recommend best knot for my boat?

The set up is very similar to the below photo except for the 2 blocks will be attached with soft shackles (they are Harken Fly blocks - photo below as well). What knot should be used for the loop connecting the soft shackles to the deck fitting? It will generally be under a light load so is a bowline acceptable or is there a better alternative?

Before anyone says just attach the blocks directly to the deck fitting, that isn't allowed under class rules - there has to be a seperate loop around the deck fitting that then connects to the blocks/soft shackles.

I think I would use a pair of opposing fisherman / double fisherman bends

I would suggest a full soft shackle to use to connect the rope of your pulleys too,

Depends on whether you want to be able to untie it easily.

Worth looking at/talking to others in your boat class - esp the leaders - & seeing what they're using & why?

Definitely this. However they are relatively hard to make, even if you are handy with a fid. I am not handy with a fid beyond basic stuff so buy mine - we use at least 6 on board, with one on the genoa clew under huge load and others scattered around various blocks.

Is the purpose of the soft shackle so it can be cut free in an emergency; say in the event of a collapsed rig trapping someone?

For me, they are easier than metal shackles, less damage, more versatile and can be placed where metal ones cannot, I use them as lizards on my fore sails

Yes good point, i did check with a couple and there is a mixture - bowline, soft shackles, fishermans bend, all sorts really so it doesn't really matter too much, i'm just looking for the neatest option.

It's not particularly so you can be cut free, more because of the position they are constantly touching/lifting off/back onto the deck, metal would be noisy and chip the deck. Also weight, it's a very lightweight boat so nice to avoid extra weight where possible.

Thanks - I think i'm going to use a double fishermans bend. I don't like the idea of a soft shackle attaching to a soft shackle.
