Author Topic:   Wiring Navigation Lamps for 13-foot Boat

The wiring on my 13-foot boat finally [failed], so I am taking the plunge to rewire. I have a 3-position push pull switch, a 4-gang terminal block at the stern, a [combined sidelights lamp] at the bow and [a white all-round] light. Jimh--I have followed your reference: http://continuouswave.com/whaler/reference/navLightSwitch.html

And here is my proposed wiring diagram. Does it look right? What gauge wire do folks typical run? Thanks. --Mike

All boat wiring should be no less than 16-AWG, and larger if the circuit needs to carry more current or have a lower voltage drop than 16-AWG can provide.

Thanks Jim - I was thinking of using 14-AWG, so that's good. What do you think of the diagram - will that work correctly?

For a 13-foot boat, I would use a SPST switch that connects the battery positive to the lamps. How many times do you plan to be at anchor in a non-anchorage area at night with your 13-footer? That's the only time you would need to show different navigation lights. Otherwise they're either on or off.

Your wiring as diagramed should work. You might want a fuse in the lead from the battery to protect the circuit.

Those who fish or SCUBA dive for lobsters at night may fall into that category. In the latter case, the all-around white light is very helpful to locate your boat when you surface.

If you are diving at night, I would think you would want to show more lights than just a white all-round. Diving activity is usually indicated with a signal for RESTRICTED ABILITY TO MANEUVER, which is RED over WHITE over RED, spaced at least 1-meter apart, the lowest light 2-meters above the gunwale.

Here are the pics of the finalized wiring diagram and the completed install. This was a fun project!
