Raw Water Supply and Distribution

This is the plumbing to manage seawater input from the thru-hull to sea-water consuming devices such as:
  • Propulsion engine (cooling)
  • domestic plumbing fittings
  • Water maker
  • Generator (cooling)
I like the concept of a "sea chest" glassed into the hull, and have seen such installations on similar boats. But I determined there is no practical place for one with the current layout. The following is the next best thing I could devise.

This is a cast bronze multi-port strainer from Marine Hardware. It has one 1 1/4-inch inlet, two 3/4-inch outlets, and one 1-inch outlet. The inlet will be fed from a 1 1/2-inch seacock/thru-hull.

The inspection dome (lid) is made from heavy duty plastic with a large plastic nut. Loosening the nut allows the lid and mesh strainer to be removed for cleaning.

 The outlets are plumbed with ball valves with easy access allowing quick shutoff.
