Sailboat DIY And Repair Tips

Know Your Rudder

After hull integrity, rudder integrity is the most vital component of a seaworthy vessel, yet most sailors pay more attention to LED lighting or smartphone apps than they do to their boat’s rudder. Before you shrug off rudder failure as a remote concern, consider that the incidence of mid-ocean rudder failures is close to 1 percent.

Hard Charging: A New Way to Charge Batteries

When my flexible solar panel gave up the ghost early last summer, I was surprised at how much motoring it took to replenish our Norlin 34’s two Group 27 house batteries after they’d been run down by a week of sporadic bilge-pumping (caused by a slow leak around the keelbolts, ahem).

Ask Sail: Transducer Extraction

I have to replace my depthsounder. The plastic nut that holds the old transducer in place was set in the hull with adhesive. The new transducer will not fit the old nut, which has proven very difficult to remove.

Solve Electrical Problems with a Multimeter

Tutorials about electrical systems and multimeters often involve theoretical analogies to flowing water. In these primers, the authors test well-designed, functioning circuits, and everything behaves exactly as anticipated.

Ask Sail: Voltage Drop

When I turned on my recently installed chartplotter, I got a “low voltage” message. Using a digital voltmeter, I measured 9.7 volts at the circuit breaker on the load side. Voltage on the battery side was 12.5 volts.

Ask Sail: Dockside Interference

When I’m at sea and at anchor, my audio system plays great, and my new digital TV converter gives me great HD reception on my new HD LCD screen.  But at the dock I get a loud hum on my audio system, and my over-the-air reception “breaks apart” on most of my favorite TV stations. What gives?

How and Why to get your Prop Realigned

The original purchase survey for my Allied Seabreeze sloop Keewaydin included a note about the fixed three-bladed bronze propeller: “some cupping noticed on all blades.” One of the surveyor’s post-purchase recommendations was to have the prop reconditioned.

Ask Sail: Flying Jib

When sailing my Baltic 35 I usually fly a large 140 percent genoa on a roller furler. When the wind gets too strong, however, I find it is too big to roller-reef efficiently. The boat also came with an 80 percent working jib that I’ve never used.

Assemble Your Own Compression Terminals

Do-it-yourself sailors have long been attracted to the concept of swageless rigging terminals, also known as compression terminals. Unlike swaged terminals, which require expensive dedicated machinery to create, compression fittings can be assembled with simple hand tools.

Ask Sail: AIS Antenna

I’m ready to install AIS on my boat. I also need a new VHF radio with digital selective calling (DSC). Will this equipment work with my current Shakespeare masthead VHF antenna?

Gear: Vallon Malizia Glasses

It’s been a long time since I’ve thought much about my eyewear onboard, but Vallon changed all that this summer when I tested a pair
