CH, I know you mean well but you do go on a bit sometimes. RCD

Why would not having insurance cover prevent you going offshore?
I've said it before... Do your own thing and do it safely.

So, there is a conspiracy between you and DD. Do tell.

JW.

So are we talking all three tanks, in line, tandem style under the floor? Presumably the tanks are flat-ish, between the longits.

JF. I don't care. Tell how you would do it.
Were you a difficult child?

John, I'm not being awkward, but I need to know why your having 3 tanks! Is extra long range a big issue? If your thinking of wieght/ballance (re: moving engine FWD) if that's the case I would have a different answer!

JF, Make a hole, drop in a tank and shove it back, drop it another and shove it forward, drop in the last one = smallest hole in deck.

But I'm also after alternatives that might work.

JW.

Where did John come from. Are you testing now? Wrong

JF. 300 miles from Peterhead to Scandinavia. Long range could well be an issue.

JW no conspiracy just a valid remark in my oppinion.

And yes I do mean well,and if by demonstrating that there are lots of considerations to take into account, when attempting to fit out your own boat in todays regulated RCD world, then in an attempt to try and help somebody who may underestimate the complex issues here,I feel It may be of help to them.

As we all are trying to save money and sometimes fitting a boat out can seem attractive but it can be a long and ardious process unless skilled.The end result can be a loss in both finance and time.

I will watch and learn from the expertise available.

On the insurance question then my list of reasons for never attempting to go offshore in a boat uninsured for me and family/ friends would fill this page.


But Good luck with it.

OK.
My opinion is always to keep things as simple as poss, so the stuff on an earlier post about valves and shifting fuel around is for me, out of the question.

The reason I wan't to know about range (I reckon you'd need 80 galls to safely cover 300 miles) is that my first option for layout would be to keep the tanks, and thus the main mass of changing weight (full to empty) as close to the quiescent point of the boat as you can so that it's handling is changed as little as poss by the changing from fully loaded with fuel, to completely empty.

If you have have three tanks, all in line and with the minimum parts=simple theory, ie, a large link between each tank, gravity feeding toward the rear, by the time your down on fuel your fuel mass will have shifted well aft!

On the other hand, if you can get your 100 galls in two tanks with a large flexi link between them (at the bottom of course) amidships (somewhere around the quiescent point) this would be, IMHO more favourable, I would then incorporate a bow ballast tank, as far FWD as I could which would be filled/emptied with sea water, race boat style(on the move) to 'tune' your ballance in differing seas. pipe your fuel supply and return to the rear tank, nice and simple.

I would fill from the rear tank, possibly from within the engine compartment as mentioned before, and have a large, say 1" breather from each tank(front top of course) which would go to a vessel of some kind to allow froth to dissipate, from this I would vent to the outside of your console, I would hope this would go some way to avoiding foam blowing out of said breathers!
Having said that, ribs don't lend themselfs to easy venting! on my real boat, the vents overboard, just below the rubrail amidships cause no trouble even if on the odd occasion they splurt a bit!

Jon, I tried to read your article in that singularly useless rag called RIB International a few weeks ago. You know, the one called "The Road to RCD". I finished it but it meant nothing to me as I don't know what RCD means.

(Obviously the laughingly-titled "editor" assumed the whole world knows what it means because he didn't explain the initials once. Totally sloppy work.)

RCD - what the hell is it? And do I give a damn?
