I heard that about Arenui so it always put me off. I think they are the only boat to set up that way. I've been on Damai and Siren and they both have dive deck at the midships or bow and everything was always accessible. Samambai has that style too and most other Phinisi boats I have seen whilst out on the seas have the dive deck towards the bow, excepting Amira which has everything at the stern, though friends who were aboard last year informed me the dive kit was always accessible to them.
