anything on a boat, anywhere.

Why not? It's pretty crush proof and kink proof. The stuff I'm
familiar with has a fairly smooth bore.

Because corrugations are traps that grab onto sea water minerals, bilge
"glop," waste, and anything else that isn't pure clean fresh water.

One drawback is that it's supposed to be terminated with wire hose
clamps which may be difficult to get in stainless.

That's another reason. Wire can cut into the hose too.

I s'pose being reinforced by a spiral instead of braid it can split
across the hose quite drastically.


For through hulls I'd look at using some *high* quality hose from the
through hull up to where the 'goose neck' loop would be, and then use
black corrugated hose after that.

Anyone had a bilge hose or non-engine hose failure? What sort of hose
was involved?

Lots of people! Cockpit drain hoses, clear water hose used for toilet
intake or sink drains...and yes, bilge pump hoses. Corrugated hoses once
were common on boats, but are no longer recommended for any application,
above or below waterline.

I'm only planning to use it on a shower drain and sump hose on an
inland boat, nowhere near the waterline so it's not tooo critical.

One thing it might be good for is sleeving braided hose to give it
protection against being crushed or chafed. Also as waterproof conduit
for cables.

cheers,
Pete.

The hose was pretty similar to that stuff. Some hot water was put down a
galley sink drain and water started coming out of the cabinet under the
sink. It took a while to realize that it was seawater and that therefore
there was a lot more available than the gallon that had gone down the drain.
As I said, a bad day. I got religion.

$$$$ hose religion I expect...

cheers,
Pete.

Yup, and that religion has added up to 0.3% of the cost of owning that boat
over 25 years.
