Sealing SeaCocks

[elliotr]

I'm in the process of buying a Ariel in Northern Michigan. I'm planning this boat as a live aboard and would like some advice on the best, easyist and quickest way to seal the sea cocks for an Ariel without an inboard. By my count, there are 5 seacocks in the hull of different sizes.

The idea of having holes in my hull is one which will keep me up into the wee hours and I'm simply not interested in the features Seacocks might offer. Is this some thing that absolutely must be done with fiberglass or is there a type of epoxy cock I can use.

I've only located one of the internal inlets inside the boat and am not sure what what internal connections the others have but I've posted photos. I imagine the best course would be to seal the piping it's self from the inside using a marine sealant.
