Just curious if anyone has explored the option of bow tanks under the v-berth floor? I realize this is reserved as a foam filled floatation area but if two saddle tanks were fabricated out of fuel bladder material ( and kept to a reasonable size ) as are used in aircraft wings, one could incorporate hatch access and still fill the remaining void with foam. As I recall, this area is notoriously lacking in foam from the factory anyway so it may be possible to get the best of both worlds with this mod, as long as sealed hatches are incorporated and the bladders are supported thoughly. Also keeping the weight of fuel this far forward will have obvious benefits.

Thanks Capt! I was hoping someone with more site know-how than me would post it. Very Happy

Dutch,

My 1984 22-foot C-Dory had a 28-gallon aluminum fuel tank under the V-berth, just forward of the porta-potty niche. Mark Toland said in an email that five boats that year included a factory-installed fuel tank in that location. I cleaned the tank, put in a sending unit and re-plumbed it only to find out that it had very small leaks in the tank where ferrous material left on the forming machine was pressed into the aluminum. I took it out, recycled the metal, and vowed never to store gasoline in the cabin again. I now have lots of glassed-in storage lockers in the V-berth, and a big one where the gas tank used to be.

I'd have to review the regulations again, but I don't think the USCG boatbuilder regs allow fuel storage in an unvented area like one would have under the V-berth. I don't have time today to find the specs, but you might start here on their site to see what they recommend. http://www.uscgboating.org/safety/boatbuilder/ventilation/183-605.htm

Catch 22 · Posted: Sun Jun 21, 2009 1:54 pm Post subject:

as a few may have seen from the other thread, i just finished installing two 22 gallon saddle tanks in my 22'angler, they are flush with the inboard side of the gunnel, mounted right up under them. The tanks extend down to about 2" from the floor and are about 40" long if i remember right. I have them mounted so that the back of the tank is about 15" from the transom, so it moved the weight of the fuel forward quite a bit, being long and skinny. My main purpose for the tanks was indeed space, i wanted as much as i could get on the back deck for fishing and lounging, i plan to build two storage boxes in front of the tanks to keep gear...
