Should / shall - you should have been a lawyer Pete!
The raft must be secure - ie not move around or bounce out of the boat. It must also be easily deployable including in the event that crew are injured.
Open top cradles have been accepted on some boats as long as they are deep enough for the raft not to move around.
The rules state hydrostatic release required. "Alternative Provisions" are permissible but I will only accept these once I have seen the boat and the operator and discussed the proposal.
CAT 3 RIBs are a minefield. The operator can request a restricted Category 3 coding from the Certifying Authority who then apply to the MCA on their behalf on a case by case basis. They are in no way guaranteed to get it.
I have lost business to other surveyors when stating that CAT 3 is not possible on an open boat.
Perhaps some Certifying Authorities have been less diligent than others when allowing CAT3................
