The best of vents will have the high point of the
loop on centreline. Not practically achievable
on many boats and the extra hose cost and perhaps
tortuously labour to install is not tolerated by most... but it is "Cadillac".
You will probably be sinking by the time water enters the fuel tank...

Russ,
Until this thread, I never gave it a second
thought. I don't know if there is a loop in
mine or not, but I'll find out! The fuel fill
hose and vent hose are still original as far as
I can tell. I hope the guys up north were
generous with the use of vent hose in
1983. Probably time to change both hoses
anyhow- they are the last of the original.

Joel, all vents should be looped as high as
practical. That is just common sense and anything is sloppy workmanship.
Joe, my fuel fill is on the outboard sloped
portion of the combing so spillage ends up in
the same area as the vent opening, easy to catch
with paper towel in place before filling. The
vent loop makes the fill & vent heights practically the same.
Since these are original installation locations,
if I was offered compliance grief from any
surveyor, insurer or regulatory type I would
send them back to review the "code of construction" for 1972.
If you're happy with your installation then send 'em packing.

Apples and oranges.
The fill where you add fuel on the 35 MK I
is on top of of of the coaming. If you are a
sloppy refueler some ends up on deck and some
in the cockpit. This does not meet 2015 ABYC
specs, although in all the decades I have been
fueling my boat this has not proved a significant issue.
The vent on the 35 MK I is on the side of the
coaming, so overflow does not end up in the
cockpit. It also is significantly harder to
submerge than it would be on the side of the hull.
Agree about a loop no reason I can seee not to do that.

Would it make sense to put a loop in the hose
that runs up under the coaming if you are using
the original vent so that water would have to
get to the top of the loop before entering the tank?

ABYC and USCG requirements say that fuel
exiting the fuel fill at 5 gpm for 5Â seconds
cannot enter the cockpit while in its static
floating position. So it depends on the slope
of the coaming. If it doesn't slope outwards
most likely some would spill into to cockpit.
There are requirements for separation of fuel
vent and other hull openings of 15 inches but
that it likely not difficult to comply with.

I suspect many of boats experiencing water
ingress through the fuel vent have a similar
configuration. That is, the fill fitting in
the deck and the fuel vent in the hull side just under the toe/rub rail.
My 35-1 is different. The fuel fill is not in
the deck. The fuel fill fitting is well aft
in the top of the port side cockpit
coaming. The fuel vent is also well aft
exiting the side of the cockpit coaming a few
inches above the deck. For water to get into
the fuel vent the deck of the boat at the stern
would have to be awash 2-4 inches deep. I
have never ever seen water higher than a couple
feet below the taffrail atop the transom. If
water was anywhere close to entering the fuel
vent I think I would be concerned about a lot
more than water in the fuel. :)
Would it be smart? Possible? ABYC
compliant? to move a deck mounted fuel fill up
to the top of the cockpit coaming and move the
vent to the side of the coaming like my 35-1
and reduce the potential for water ingress?
