Heavy duty progress capture

[Pete Mctree]

I cannot think of a device that could do this. You would have to use a friction bollard or something similar manned by someone really switched on. If you were to overpull the rope with the boat, any system would probably be destroyed without a breakaway

[Mr. Squirrel]

A prusik would stop that from happening but theres no way to control it with the rope moving at speed on the haul and you'd probably have to cut it off in order to lower.

So long as the knot held that could be an alright idea. Put rope in bollard, very tight, cut prussik, dump 500kg into locked off bollard.

Not sure how the pro traxion or wall hauler work with regards to lowering. Sure weight would be an issue if they are designed for light haulage, but i'm thinking a combo set up of em some how & file the teeth off if they have em..

 

Not clear on what the application/operation is you are trying to achieve & why a speed boat is involved, sounds like fun though & best of luck with it...

We need discriptions and diagrams, This sounds very interesting.

Come on don't be shy.

Thanks for your thoughts on the matter guys.

I came across one of these last night:

Looks like it might do the job. Certainly worth testing anyway.

Thanks again.

The rig is great yeah but too much friction for this application.
