Humber 6.4

I am going to convert a Humber 6.4 to take an inboard fuel tank. I am after any advice on what size of tank is required, and also the best location for it. The boat will end up with a 150 or 200 hp engine which may determine the best position as far as balance etc. is concerned. Any information on this subject will be greatly appreciated.

Depends how fuel efficient an engine you are going to have. An older 2 stroke will burn petrol at a prodigous rate! We have a 40 gallon underdeck tank on a 6.45m RIB and run a 150 Merc Optimax if thats of any help.

There are no gas stations in the sea, so take under consideration your fuel consumption and your needs. For instance I run a Mercury 115 (drinks about 0,9 to 1 lt per mile) and I have 180 litters of fuel in 2 seperate underdeck tanks.

Ideally you want to put it under the deck to keep the centre of gravity low, and have it as large as will fit in the space.

This is a substantial project, so you may as well maximise your range -- you don't have to run with it full all the time if you don't want to, but at least you've got the option. Anything to avoid refuelling at sea from jerry cans . . .

For my 2-stroke 115 Mercury I opted out for two 90 liters tanks.

They are positioned under the deck and as close as posible to the
center of the boat. I also have a switch which allows me to shift from the one tank to the other.

I do not fill both of them all the times. Usually I use the one tank
that gives the best balance in my boat.

Using two tanks instead of a big one might be more secure as well. For instance, in places where I am not sure for the quality of the gas I fill the two tanks from two different gas stations .

For the size of your boat and engine I would consider a capacity of 240 liters.

As a final point, I think you should consider using anti-explosive tanks.
