We have a 585 Ribtec coded for six, we carry a cannister liferaft in a cradle with hydrostatic release. The balance/weight on the boat needs to be right. I got the balance wrong on first brief and moved it forward.Our Larger coded RIBs have cannisters and think these are more suitable for RIBs despite Previously having a 6.5 coded with an eight man valise which was held on the deck with quick release straps. I believe the coding now states this valise would have to be in a locker now.
I would suggest a quick call to Duncan at

who has inspected and cleared all our ribs previously. He also uses Ribnet so may be along shortly with wise words.
Also code can be checked here
http://www.mcga.gov.uk/c4mca/mcga-mn...23704CA95E9786 section 13 refers to liferafts and states
.Liferafts should be carried either:-
i) in approved FRP containers stowed on the weather deck or in an open space, and fitted with float free arrangements so that the liferafts float free and inflate automatically; or
ii) in FRP containers or valise stowed in readily accessible and dedicated weathertight lockers opening directly to the weather deck.
