Itís certainly possible to overstate the risks but at least one person here jumps off the boat whilst the engine is in gear unattended. Itís also been suggested extending kill cords (generally a bad idea).

Some of the perceived risk variance might be down to different types of boat (and maybe different slipways). On a large boat you are a long way from the helm, and likely high above the winch post for clipping on. On a small boat a bunk trailer may not need to be that much deeper to float on/off than rollers etc.

Yep, on my boats it's impossible to reach the winch post from the bow, rollers or bunks.

Indeed. Bunks are frequently lower than rollers because rollers need height for the support bars and then more height for the axle bars.

Every dsv I've worked on in the last 15 years the umbilicals have had a physical stopper that prevents intentional or accidental deployment of too much umbilical its never left to the tenders or bellman

I think the lower profile of bunks is a big advantage of a bunked trailer keeps the load closer to the road and helps stability

OK...... on most RIB's if your hung over the bow reaching for the winch post your way, way more than a metre from the helm controls, are you not? ( unless you've got a baby size boat )
'No one leaves the boat' - jeffstevens has slightly different approach to your extraordinary long arms technique , and I quote 'jump over the side and attach the winch' - he's not aboard!!

As touched on by other posters, common sense is the key, many local slips to me are very,vey busy and not places to risk (however small) someone else's well-being I'm with the "nursery-paddling committee" at Lymington ( come-on, what would they know?? All those decades of experience and knowledge ) FYI the RYA training is the helm (if running) is manned at ALL times, one hand on the throttles and no excuses - period!

Who mentioned launching, we're having a nonsensical argument about boat recovery

The reason they're so busy (and probably the reason you don't need an aux) is people getting in everyones way spending most of their day paddling about on the slip trying to launch and recover their boats and never seeming to get much further than the harbour entrance.

PS

I'd imagine the Lymingtons "nursery-paddling committee" probably know how to make lovely fairy cakes and real lemonade..

Looking at the OP's first post, there may be some confusion.

He refers to "roller bunks". Most (not all) roller trailers here are swing-beam rather than roller bunk and the "V" in the swing beam is what gets the height of the boat down for easy launch/recovery. The straight axle can scupper this a bit and is the limiting factor. I have heavy duty rubber "D" fendering on top of my axle and the boat does tend to contact it during launch and recovery but that's the price of getting the boat as low as possible on the trailer.
Never tried roller bunks, so can't comment.
