Seacock Question

[Ocean Girl]

Casual,
Gate valves on a thru hull need to be tossed, they are a safety hazard (if I understood you correctly). So ya need to buy all new seacocks ( sorry).
Go bronze or marlon ( spell). For a Cabot Rico I'd go Spartan, but others may have a better idea.
Cheers,
Erika

Ocean Girl I,aggree,as part of my refit seacocks will be installed,how ever there are 2 areas that will not permit a seacock no room .Thus loking to refurbish the old ones.I'll try Spartan Thanks

Azek, why use PVC for backing material it has little strength and PVC can be attacked by a lot of solvents types. If your hull is GRP, use plywood encapsulated with GRP. ( 4 times the area is way to big an overkill) all you need is a pad about 2-3 " wider then seacock base

True seacocks are bolted to the hull with 4 bolts, most these days are actually bronze standpipes with a ball valve on top. good but not great.

If your boat is subject to freezing in the winter or kept in fresh water, be aware that water can freeze in the hole of the ball, vetus now do valve with a drain spigot for just that eventuality.

IN a GRP boat there is no advantage and some disadvantages to bonding

+1 for Spartan
They are a bit pricey but very nice. Smooth like buttah!
I replaced a broken Wilcox-Crittenden and it's nice. Water tight and opens/closes with one finger!

There are narrow clearance seacocks ... Now if I can find them on the web my Internet is spotty.

as I remember, the spartans are a pretty small size compared with the older tapered type. ?
edit: I guess it's the groco....

Casual, A set up as in the picture using a Groco Flanged Adapter, street elbow and a ball valve will solve a lot of clearance problems. You really need to get rid of the gate valves.

HopCar you must be reading my mind,I,have just such a set up for the engin water intake,just a thru hull coming thru with the 90 attached then a bronze valve unknown manufacture but still good after 30 years.I,plan on doing as you shown if I,have vertical clearance.I,have to do a total of 7 .
Thanks very much for the post.

Your WPB Store is 30 miles away,I'll be down soon putting my list together,first I,have to deal with my bottom albative over hard paint,want to go hard.Albative is a nightmare to sand.Why did I,buy a FULL Keel Boat?

[shamrock]

I used interlux bottomcoat NT last year in the chesapeake with great results, only one coat over bare gelcoat. It's supposed to be a mix between hard and soft paint. 74 bucks a gallon too.

Would you rather sand laying on your back or breaking your neck, like on fin keels?

[casual]

delmarrey,have done both,how ever I,have never DA a bottom down this far,as the albative goes the old hard must have had lots of copper as it eats 80grit a disc every 2 sq ft. and I am not getting thru to gel.Thank Goodness for Rain this after noon.
