Thru hull fittings – below the waterline

30 Mar

Below waterline thru hull fitting

I often see this problem on smaller older sailboats. A drain for a sink or cockpit drains that go to a below the waterline  thru hull fitting. Even though this installation was very solid it is still not safe without a seacock. To conform to ABYC  H-27 or Transport Canada TP 1332 section 3.3.1 below the waterline thru hull fittings shall have a seacock in order to shut off underwater penetrations. A ball valve is the best type of seacock for this application. Apart from saving you from sinking in the event the hose comes loose it will also allow you to do maintenance on piping etc. without having to haul your boat.

Bad DC connections

23 Mar

This is pretty common. A piece of equipment is relocated or added and the DC wiring is short. So the temporary measure to connect the wires is forgotten about and becomes permanent. In this case it is positive cable from the battery charger and so is potentially carrying 50 amps. Note the stainless bolt making the connection.


Glassed over Keel Bolts – Jeanneau Eolia 25

10 Mar

Never a good sign when you come across amateur fiberglass work around the keel of a sailboat. In this case the keel boats have been glassed over which was probably effective in stopping the leak! At least for now. Of course there is no way for an owner or a surveyor to judge the condition of the bolts anymore and the bolts themselves are now soaked in  water year round slowly corroding as the water is depleted of oxygen…

Leaks through the hull to keel joint should be repaired by resealing or caulking the joint, from the outside.Image

First Post!

10 Mar

I spend part of the year surveying yachts and commercial vessels for a variety of clients. They might be new buyers that want an expert to look at their dream boat or an owner that needs a survey to renew his hull insurance. At times I also do survey of damaged yachts. Those are often the most interesting cases.

Most modern boats are pretty well set up and follow the required codes but I often run into strange, dangerous or just plain bad repairs or installation.

This blog will point out some of those things I come across and hopefully serve to educate both the reader and I.

Looking for your comments.
