Of thru-hulls and seacocks...

Are there any rules/regs about thru hulls and seacocks? Is there any equipment that has to have a dedicated thru hull or can you combine anything? Do certain ones have to be a certain size? And finally, do certain ones have to be above or below the waterline?

Yep. It is ABYC H-27 — Seacocks, Thru-Hull Fittings, and Drain Plugs

This standard is a guide for the selection of materials, design, construction, and installation of seacocks, thru-hull connections, drain plugs, and other fittings that penetrate the hull at or below the maximum-heeled waterline.
This standard applies to all boats.

It is available for $50 here: SEACOCKS, THRU-HULL CONNECTIONS, AND DRAIN PLUGS: American Boat and Yacht Council (ABYC) Store

Re: Of thru-hulls and seacocks...

There are no rules, only guidelines, some of which are often way off the mark , far removed from reality. Most white plastic thru hulls are extremely brittle plastic, which can easily be kicked off with the heel of the foot, leaving a 2 inch hole in your boat. A bit of heavy gear shifting can do the same. A fire on board will melt plastic thru hulls quickly. Bronze is a far better choice.
Black Marlon is a far better version of a plastic thru hull, as it is soft, like polyethylene, and cant crack. Being black makes it far more immune to UV degradation.
On my steel hulls, I use stainless type 316 , sch 40 pipe nipples, welded in, with a type 316 ball valve, screwed on with teflon tape. There is no tougher, more reliable thru hull available anywhere. In over 40 years of use, they have given me and my clients zero problems.
