Yeah, probably not much of a worry. The current series of Oceanis boats (well, the 35, 38 and 41) and very small propane tank locker. Only one 5 lb tank can fit. After talking with a local knowledgeable guy, I am going to fill the spare and keep it at home as there is no good, safe place to store a spare tank on these boats. When the pressure is getting low in the tank on the boat I will swap them.
