RIB 10'

I have a new to me 10' titan RIB. I have powered it with a 9.8hp 4 stroke outboard. The engine has electric start - I'm finding pull starting too difficult with my age and stage 🙄
I would appreciate thoughts about where to install the battery and gas tank for most efficient operation.
I live a mile offshore and use this boat to haul my groceries, etc. to my island, and the garbage/recycling off. It works hard for me!!
In sailing season, it will also be the dinghy for my 28'sailboat. Tnx for your thoughts.

Re: RIB 10'

Generally, planing hulls perform best with the majority of weight just aft of center. Unfortunately, that’s not usually a convenient place to locate fuel tank/battery & supplies.
If you place the Batt/Fuel at the transom, you’ll likely have move yourself far forward to get onto plane, at which time you can move back amidships. A tiller extension is useful here.

Re: RIB 10'

As Gordon wrote, place the battery and tank as far forward as possible, to counterbalance the weight of the motor. You need to make your own judgments.

Since you'll already have a battery aboard, you might also consider adding an automatic bilge pump in the drain well at the stern, to handle the rain. Here's a picture of my setup. Note that I added a check valve to reduce pump cycling in the tiny sump well.

I'd put both the battery and the fuel tank in the bow, keeps you from having to lean so far forward and may keep you from having to extend the tiller too.
I have our fuel tank in the bow and it helps, we don't have a battery, but if I did, I'd put real position lights on it.

Re: RIB 10'

A 10 hp motor does not need that big of a battery, I'd also consider mounting it in the front but a pretty small 12V motorcycle/lawn mower battery isn't much weight, and an adventurous person could probably make up a battery pack from Lith/Ion that would be even lighter still.

Anyway, I'd be tempted to try that, and for gas go with a pair of small cans like 1 or 2 gallon and keep one up front and the other in the stern by the motor. When you empty a can move the front one back, then fill the empty one and store it up in front.
