Dingy lifting block Twist...why?

[Greggegner]

Looking for some knowledge or ideas. I have a nice set of Davits on the boat but when lifting the dingy the lower block (can swivel) twists tight make hoisting difficult. I have double braid line on the blocks. What can I do, change the line to...

Make sure the line is threaded through the blocks properly. Mine did the same until I rethreaded it properly and now it works sweet.
Go to Google images to see the different pulley setups and follow them.

Particularly if triple blocks, google proper reaving.

Remove swivles. The shakles should give enough movement.

All good tips above. Also crummy cheap double braid can cause this. If the above fails try some higher tech line, of a smaller diameter, like a polyester jacketed dyneema or polypropylene double braid...Runs thru blocks 6000% better than Sta-Set stuff.
