Do yourself and the boat a major favor. Do a professional job and glass
the hole. For safety sake if for no other reason. You won't have
electrolysis issues and potential leaks. If you plan to reuse it at
some time, just close it and take the handle off. Caping it might not
be the right move.

A bronze cap of the same material and schedule will be just as
reliable as the thru hull which is a no back up component. Filling
the space with something resilient and flexible will exclude water and
also serve as a plug. I'd much rather depend on this with the thru
hull and inner nut sandwiching the glass that grinding back the hull
structure and depending on secondary glass bonds.

I would just leave the seacocks as you suggest except that they are
gate valves that I'm replacing and relocating at the same time.

Roger,

I agree with the other posters. If you read about boats sinking, it's
seldom from secondary bonds popping off. More often than not it is a
seacock failing in some way. I figure you have a number of failure
points with a capped off seacock (cap coming loose, corrosion of
thru-hull, long term failure of caulking (like in 10 years).

I would go so far as to say it would not pass a survey with just a cap
on thru hull.

Evan Gatehouse

From a strength, corrosion, and functional standpoint:

If it isn't safe with a cap on it, it isn't safe with a seacock and a
hose.

(I'm talking about capping the bronze through hull; not the seacock.)

OTOH there is no way a scarfed out and secondarily bonded plug will be
as resistant to flexure and impact as the original hull. I would
agree that it would be acceptably safe and strong but still not to the
original standards. The capped seacock, especially with seawater and
the electrical path isolated from the inside of the pipe by proper
plugging, would be more reliable than it was originally.

I asked a well regarded and experienced surveyor about the through
hulls. Here is his response:

"The standard response to unused thru hulls is to cap them. The
removal
and reglassing is suspect. I think your approach is the proper
solution and
will last beyond any other approach."

I don't understand how "reglassing is suspect." As for capping
thru-hulls, one very rarely sees that and it leaves a vulnerable point.
You might consider asking the ABYC.

When it comes to holes in your hull, the "more is better" approach
doesn't sound good.

Ken,

I'll be bringing my boat up to Cape Breton this Summer and would
appreciate your recommendations regarding suppliers of
necessaries/desirables for sailboats in the area, as I'll be doing a
lengthy refitting and am unfamiliar with suppliers beyond Port
Hawkesbury, though please don't omit recommendations there either.

On the other hand if you've discovered better sources outside of Cape
Breton, please send them on :-)

Appreciatively,
Courtney

Hi Courtney,

Port Hawkesbury is about two hours away by car so I don't buy much there.
Most of the suppliers in Cape Breton service the commercial fishing fleets
and other commercial users but some deal with recreational boaters as well,
such as Sydney Ship Supply (now owned by the IMP Group of companies):
P.O. Box 38
Victoria Road
Sydney, NS
B1N 3B1
Tel: (902) 564-5425
Fax: (902) 539-0904
http://www.impmarine.com/impmarine/

I'd probably be more helpful if you had a specific request for an item or
service. We search for many things online. I used to have all sorts of
links collected together somewhere but I can't find them anymore. Here a
short list of online suppliers in Nova Scotia and beyond:

These guys are based in Halifax, NS: http://ca.binnacle.com/online/

As a http://www.mmosonline.com/

I've dealt with both, both online and by calling or visiting their stores,
and am happy with the service.

In Toronto: http://www.hollandmarine.com/

The next two have a somewhat limited online presence but offer used
equipment.
