Even a slight belly will cause problems. From what I see in the pics, you will need to cut notches on the top of the stringers (of course this means more glass work) to get the vent hose to the starboard side. Or you may be able to run the vent hose forward, then to starboard behind the inner liner between the bulkhead/step for the casting platform and the fishbox, then back aft under the rodholders. The problem with this is it wil be difficult to secure the hose in the areas behind the inner liner, not to mention it will be a much longer run.

Again, you do not want any place where the hose dips down, then back up again. This will cause venting issues.

I had a RIB tender on one of the yachts I ran that had the fuel tank vent on the side of the console. I never smelled gas, except when fueling.

Good luck.
