Electrical Tools and Supply Recommendations

Having a good set of electrical tools and supplies on board is essential. Saltwater, dampness, and constant vibration wreck havoc on electrical connectors and wiring. Being able to quickly test, diagnose, and fix a problem while at the dock or underway is important and being able to preventative maintain the wiring and connectors is even better.

Many of us had or have basic tools on our ‘first boat’ and gradually built on those tools as the boats got bigger and more complex. So, the tool recommendations are separated into 2 categories: “Basic” (DC only) and “Advanced” (AC and DC power):

  • Basic Tools (DC only, smaller boat)

  • Advanced Tools (AC/shore power, inverters, larger boat, etc.)

  • Basic Supplies (DC only, smaller boat)

  • Advanced Supplies (AC/shore power, inverters, larger boat, etc.)

Note: most of the tools and supplies below have links to Amazon.com. This gives you an opportunity to gain further information about the tool, read reviews and optionally purchase the items and gives us a small percentage of earnings for our Development and Cruising Kitty, which we thank you in advance for.

Cordless Drill/Driver is essential for pre-drilling screw holes, installing screw/bolts and cutting hole (cables, deck fittings, etc.). We started with an 18v set but have downsized to the 12v with exception to our Makita angle grinder, jigsaw and vacuum (REALLY NICE). The 12v tools do the trick and cut with smaller precision, such as 12v circular saw or recipro saw.

Tip: For large projects, consider purchasing connectors in bags of 25 or 100 and wire by the spool, especially Safety duplex.

Note: Split Tubing and Spiral Wrap must be Self-extinguishing in accordance with UL 94 v.2 and ABYC.

Optional Items:

  • Replacement LED bulbs no.58

  • Replacement LED bulbs no.1004/1156

  • Replacement LED bulbs no.90

  • Replacement LED bulbs G4 Warm

  • Replacement LED bulbs B15D Dbl

  • Replacement LED bulbs B15D Cool

  • Led Dome Light SeaSense

  • Led Reading Light SeaSense

  • 12v test battery (old power tool battery or two 6v in series) with a fused alligator clip for pre-testing or isolated testing of devices

Tip: Consider using marine grade Nylon connections which will better resist corrosion, cracking and falling apart in a marine environment. And if not using heat shrink connectors, always use heat shrink adhesive lined tubing to help protect the wire against corrosion from moisture and strain on the connector.
