Essential tools for rewriting (left to right): fish tape, RJ45 crimping toolelectrician's tape, 10 pound mason's line (pull string), 1 insulated terminal crimping pliers, long-jawed hemostat, and wire cutters.

A Smart, Easy Way to Rewire

Running the wires for new electronics requires your best cursing vocabulary, lots of sweat, twisting body contortions, luck, and the occasional bandage. For tips on how to make this job easier, we turned to PS contributor Bill Bishop. A professional marine-electronics installer, Bishop has many ingenious ways to thread a wire from point A to point B.

Small Wire Connections: Best Methods

Connecting two standard-size wires is pretty straightforward: Grab a ratchet crimper, adjust it to fit the crimp connector, strip the two wires to fit into the butt connector, slide the wires into the connector, and squeeze the crimper. The required materials are readily available: butt connectors for inline splices, ring connectors for terminal blocks, and a dab of anti-corrosive grease for the bolts and rings. Done right, these connections can survive some extremely tough conditions. In a recent test of anti-corrosion greases and connections, we demonstrated how these connections can last up to five years in the worst bilge conditions.

The batteries pictured are Rolls S6 250 flooded cells, nominally 281 a/hr. They came with the boat and are of unknown age but currently seem to work OK. They are not the cell I would pick as they are a lightweight battery. The clue is that the spec sheet gives a CCA number. True deep cycle cells don't have that. The taller L16-EX is rated at three times the cycle life, about 3,750 cycles to 50% DoD compared to these at 2,000. You really do need to look at the full spec to know what you are getting! In Canada these are currently around $320 com-pared to the L16 at $590. The black battery is the starter battery which is a simple H/D car battery that starts the engine and supplies the windlass.

O’Day 30 Used Boat Review

Over 350 O'Day 30s were built between 1977 and 1984. During 1984, the 30 was modified by changing the keel and rudder, and the stern was lengthened to accommodate a European-style boarding platform. This "new boat" was called the O'Day 31, and it stayed in production until 1986.
