Underfloor Fuel tanks

[Sonar]

Looking through the forum threads and I have seen a lot of built underfloor tanks.

For a 6 mtr rib what do the members suggest as a suitable capacity for 2 tanks.?

150 ltrs plus.? or more...

what does your 6 mtr tanks hold.?

is this for a single 200 hp engine.?
what sort of mileage do you get for that.? approx.

I was thinking for a 150hp 182ltrs in two tanks would have been enough for me I will have to rethink .

Obvious, but it depends on how far you want to go.

Bargain.

As suggested, depends how far you want to go and how easy is it to fill up, do you launch each time you use or is on the water. Our 6.3 with a 175 does very roughly 1L per mile. We have two 75L tanks in the console. Gives us plenty of range for our usage and easy to see how full they are. Horses for courses.

I only have 120L ( i found to my cost ) despite being told it was 180, to run my 200. I reckon it about 4 hours at 25knts , 3 hours at 35knts, and about an hour and half at 50knts !

I managed , but then I dont go long distance and keep it topped up whenever i can ( on the water).

Sometimes but it's also useful if your away camping etc with no waterside fuel

We've done a few trips to the Isles of Scilly where getting fuel can be a pain

We camped for a week at Ardmair Point just north of Ullapool last year and topped up every day with 3x 20 litre cans, but by the end of the week the tank was getting a little dry as we explored the coast

Great for recovery and the 550 mile drive home when the boat is 200 kg lighter

My next rig will have a larger tank 30-50% more

Well I now have a 210 ltr tank ready for conversion .

However it looks very large and will be half in and out of the deck.

So i am now thinking maybe making a grp tank that will go under all the deck.

This is the type of resin

anyone got any comments on a grp tank ?
