First 375 help needed!
Hi all, I'm looking at a First 375 and strangely it seems to only have two flexible water tanks under the salon seating. I'm assuming that this is not standard and that originally there would have been built-in or at least solid tanks - but where would they have been?

I also need a replacement stainless pulpit, does anyone out there know where I could obtain one or could recommend somewhere that could make one to order that's made one before, i.e. wouldn't need to measure up on the boat? I'm in Grenada but would import from the US or wherever - Beneteau don't have one, I've already checked, they're also very expensive from Beneteau.

Flex tanks are not uncommon on the First and have much to reccomend them. We've carried 105 gallons of water between two flex tanks in a similar arrangement since 1986 without difficulty. ANy good stainless shop can make the repairs you think you need.

Well that's good to hear, the current flexible tanks are plainly not original, they're too new, but the evidence suggests that there never were any solid tanks fitted so maybe they were always flexible...

I also have flexible water tanks under the salon seats on my First 42. They are new-looking, though, so I don't know if it ever had rigid tanks.

So far the only problem I have had with them is that when they're full starboard one separates the A/C ducting. I haven't bothered to fix this since I never use the A/C...

Interesting. Are they the only water tanks, or are they additional to fixed / rigid tanks?

Anyone know the shaft diameter on a First 375?

Which shaft?

Mine only has the flex tanks. I assume you meant the prop shaft, but I don't know the answer.

Oops. Propeller shaft. Sorry.

On those vintage Beneteau first series boats, they all had bladder tanks. Advantage's to bladder tanks are that they do not rust or crack, and are easily replaceable without having to cut up the boat like solid s/s or fiberglass tanks. Holding tanks are usually bladders too. Replacement pricing, usually good too. LAS First 38 owner

The prop-shaft on our boat (aux-powered by a 4-108) is 30mm.

On the First series yachts, the original buyers had a choice of the flexible water tanks or stainless steel tanks (albeit at extra cost). Our yacht, delivered in Europe and sailed back to the US on its own bottom, has flex tanks. Our sister-ship, manufactured at the same time as ours and only 15 hull numbers apart, has the optional stainless steel tanks. If you have the flex tanks, a couple of things will be helpful. Firstly, place a layer of "Dri-Dek" interlocking decking tiles under the bladder that will allow air to circulate around and under the tank. If any moisture does make its way under the bladder, one does not want it trapped. Further, it is helpful to add a couple of 2" or better webbing tie-down straps across the mid-sections of the tanks with plastic bayonet clips to free them if necessary. These will help hold the tank securely when full in a seaway and will relieve some of the stress on the corner tabs of the tanks themselves.
