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 http://www.saundersmorganharris.com/da/18577
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.
