Polwart - I agree with your sentiment - you really should try and keep the rib with the wet side in the water when you have vulnerable passengers on board. BUT

1. If someone goes for a swim from the boat they are not certain to die

2. If you strap someone onto the rib and turn it upside down they might well be certain to die...

So you really need to take the probability that someone will go for a swim AND be left permenantly harmed / dead and contrast that to probability of parking your boat upside down.

Now... go to maib site and look for 6/2008 - the one where the army overturned a dory with kids on board... So people do make wrong decisions. In that case they realised the condititions were not what they expected and had turned back but screwed it up...

Then go look at Plas Meni's report on maib...

If you drive a boat like you drive your car (yes I can still recall your boat coming past your car on the way home from Loch Lomond!) I'd be reluctant to lock my child to the seat...

Another concern about using a weight is what will it be doing during the boats inversion? The last thing your passenger will want is to be bashed about by a free flying weight before being dunked.

Absolutely. I sort of see it, on a short coiled line, in a small bucket. Said bucket being fixed down so nothing comes out unless the boat is upside-down. But I haven't completely convinced myself this is going to work yet. I'm thinking aloud - well online - really.

Shiny - the problem is I have to weigh up the high risks of a restraint if the boat flips, however unlikely that is, against the less serious but constant risk that this unrestrained passenger will just slip quietly over the side due to overactive curiosity, unless someone keeps one hand on her at all times. I guess the Health And Safety view would be that she fails a risk assessment for RIBbing. But if I hear "she can't have fun because she's disabled", then I tend to say "sod that" and keep looking for ways round it.

its not going for "a swim" its falling overboard at speed. cold shock, head impact, prop collision, hypothermia, getting "lost" (if it takes you 30 seconds to spot someone go overboard at 30 knots you are half a mile away - try spotting a person at 0.5 NM in anything less than ideal conditions, shouting is ineffective at 30 knots over engine and wind noise - so even if spotted going over it could take that long to alert the skipper). The risks of death from falling overboard are not insignificant.

I don't know what the OP's DD's disabilities entail but if she is liable to go "wandering" even when told not to - then her risk of going overboard is higher than a typical passenger and a belt would reduce that. Of course an able bodied adult next to her on a bench may achieve something similar - but even with a 3 yr old that creates complaints about independence and gets tiring on a long cruise.

nice oxymoron to achieve the more emotive language! Its not certain you die in that circumstance either. If the occupant can release themselves, if the other crew members can release them. Even if it were certain the anecdotal evidence from here is that capsizes of ribs being used in normal family cruising circumstances are extremely rare (in fact I can't recall any) MOBs are also rare but those passengers are generally good at holding on and balancing - even then there have been one or two!

probably wouldn't have happened if they had used a RIB! Reduced risk if they had loaded the boat better and deployed the trunks to get rid of the water. Whilst no one goes out expecting/planning to capsize - if the conditions are marginal you don't go with those who would not be able to help themselves. Many people here have different limits for when they will go out themselves/friends and when they will take their kids and the same logic applies here. Likewise how hard they will push their boat.

This is another case which doesn't fit with a family cruise model. They might have been reasonable for able bodied teenagers but again I don't think many people would take young kids or mobility restricted adults in difficult conditions.

your memory is clearly flawed since the trailer didn't overtake the car - however I do drive my boat the way I drive my car - if there is someone I care about "on board" I show extra care

What about having them "tethered" to a fellow passenger, having the tether short enough to ensure that they do not fall out of the boat - or at least not alone!

Siochair thats not a bad suggestion. If the fear is going overboard unnoticed there are option which have been discussed here before similar to kill cords that show a light / buzzer to the skipper.

There is this system from NASA but I'm not sure if the OP wants to spend this much. http://www.nasamarine.com/proddetail.php?prod=Mobi

Ah no - there have been "diy" solutions suggested here which would be about 30 to kit a boat for 3 crew!

30 quid does seem to be ever so slightly more reasonable that the cost for the Nasa system
