I'm pretty sure that Andrew Simpson fitted non metal seacocks in his current boat but I don't know how he's getting on with them. I think he was off to the Med via Portugal so don't know whether they were installed with warmer climes in mind.
If there's the remote possibility of North Sea temperatures causing these things to snap off I'll stick to the old Blakes and my tin of grinding paste.
I can't believe though that AS would have specified these if that were true.
Dont worry! PBO used to print things that were popular but not always fully reserched by the readers that wrote the articals! i still have those old copies Now were into the information ira,
Ive never heard of "patay" but i fully intend to fit "plastic" seacocks once ive looked into the whole thing more. if i have to change them every X years for safty i will but im sure that for a wooden boat non metals the way to go.
My post before was only a note and in no way reflects the current development or suitability of non metal seacock for use in a marine enviroment
Now lets just wait untill an informed source posts usefull info for us to follow up!
all my wooden boats have throgh hull tranducers the last was renewed in 1964 by another owner and still in service?
When i transmit useing SSB if i take a wire from my bronze seacock and another to my rudder shaft and attach the to a bulb i have lighting! well its not that bad and i do have two very large ground plates, but still worrying!
Patay make an extremely fine seacock, very robust and the chances of them failing are virtually zero..... and I have several of them if you want them for a very reasonable price. They were specified on the plans for the steel boat I have been building and including spares, I bought a total of seven of them. My problem was not with the seacocks themselves but with finding a decent hosetail to fit them.
Patay do supply hosetails but they are nowhere near as robust as the seacocks for which they are intended. The Patay hosetails are made of a relatively thin plastic and are stepped to fit several different sizes of hose. Also, each individual step is only long enogh to get one jubilee clip on and not two as recommended below the waterline. In my opinion the hosetails were not up to the job and I was unable to locate a better one that fitted, was "up to the job" and did not leak. I posted the unabridged version in this thread.....
Because mine is a steel boat I did not want to use a bronze hosetail but if yours is a plastic boat you would not have the same problem. Perhaps using a bronze hosetail would seem to defeat the object of using a plastic seacock but at least hosetails are relatively cheap and easy to replace.....
