3. Quickness of evacuation:• on average a shorter distance is to be covered by evacuating persons,• simultaneous access to all boats from particular decks of ship,• less confusion than during evacuation by using a boat system having side boat davits when all passengers gather on one and the same deck, • a shorter evacuation process as all the boats are lowered simultaneously after starting up only one common driving system (the starting-up of the driving system which lowers the boats is preceded by the simultaneous lifting-up of all gangways and releasing the hooks (releases) of the mechanisms blocking the boats during ship voyage).
