Thx. We needed solution… and developed it.

Yes. RAM mount. Absolutely best product on the market.

We organized everything so it can be easily mounted on our working raft…

Nice raft! That looks like a good expedition boat!

:joy::joy::joy: We call it raft…

Other is called boat …


But ASAP we need cabin :joy::joy::joy:

That makes me think of a slightly tangentially related question. Whats the best way to secure a tether spool to a boat? How often is the ROV pulling on the tether to the point you would be worried about it going in the drink? Would a big side mounted suction cup work for most hulls? What about usage from a dock? I’m thinking some sort of side clamp mount with various accessories (maybe a ground anchor spike, dock “T” shaped slot anchor, suction cup, cable anchor cleet of some sort , magnet, etc. )

Tim good point…
Whatever you do it should be properly anchored to a boat.

That looks fantastic. Would you mind sharing details on the slip ring?

Yes of course

The solution looks great!

It looks like you are using CAT-5 cable. How did you manage to get neutral buoyancy? And is there any compression issue at depth?
