Gear

Viewed from astern, this propeller rotates counterclockwise with the engine in forward gear, making it a left-handed prop. The numbers stamped on the hub indicate that it has a diameter of 16 inches and a pitch of 11 inches.

Gate – a gate is a section in the lifeline that can be opened to facilitate boarding and is normally located between two closely spaced stanchions.

Ensure your first line of safety really is safe Issue 72 : May/Jun 2010 Lifelines are designed to reduce the chances of your going overboard. On many boats, however, these systems are poorly designed ...

Sigfrid’s new tiller is elegant and functional (at left). It replaced a shorter tiller that was used with an extension, at top below, when it was not connected by cables to a steering wheel. A supply of secondhand oak floorboards provided the ideal material for laminating into the desired shape, at bottom.

The aluminum and plastic oars outlived one dinghy. When they eventually succumbed to age, Richard made replacements, above. Using lumber from a building supply store he began by gluing nominal 1- x 2-inch “wings” to a 2- x 2-inch shaft, below.

With a couple of garden-hose fittings, Dan made a hose extension with a built-in valve to simplify filling his boat’s sundry water receptacles.

An in-line valve eliminates the on-dock sprint Issue 75 : Nov/Dec 2010 Upon coming into a marina, our first priority is what we like to call “watering the boat.” The procedure begins with filling her ...

Charts accumulate in great numbers on a cruising boat and storing them flat often presents a challenge. Connie turned the problem on its side and attached a “chart basket” to a bulkhead.

Flat, yes; horizontal, no Issue 76 : Jan/Feb 2011 Finding charts we’d stored on board our 34-foot Creekmore, Eurisko, used to be a constant game of hide and seek. When we put charts on the navigation ...

To get the dinghy on board, Richard and Beth first disconnect the lower lifeline, then pull the dinghy by its painter up and over the ship’s gunwale.

A little pram dinghy is a workhorse and a comfort Issue 76 : Jan/Feb 2011 We wouldn’t cast off without our 8-foot pram in tow. It’s convenient to have her in the water and ready to go when we finally ...

Solar panels will generate more juice when turned to face the sun directly.

Two-axis mounts make solar panels adjustable for greater gain Issue 77 : Mar/Apr 2011 Having cruised through the South Pacific twice, we knew the value of solar panels for keeping our batteries charge...

This schematic shows the basic components of a reverse-osmosis watermaker. In practice, the devices may be much more complex. Some models, for example, use the pressure of the exiting brine to assist the high-pressure pump, thus conserving energy.

Pressing pure water out of the sea Issue 77 : Mar/Apr 2011 Osmosis is a natural process in which molecules of a liquid spontaneously pass through a semi-permeable membrane. The direction of fl ow acro...

Jerry prods his jug bucket to perform in front of the camera.

Thinking beyond the pail Issue 78 : May/Jun 2011 Aboard Mystic the “ship’s bucket” is an important piece of gear. When it’s inactive, it holds the vacuum cleaner and is buried deep in the port cockpit...

Danny built Olo’s radar tower, at left, from readily available aluminum plate and tubing, below and illustration on facing page. He sets the angle of the radar manually by adjusting a turnbuckle, on facing page.

A home-built tower with manumatic leveler Issue 78 : May/Jun 2011 Several years ago, my wife, Kari, and I decided to venture beyond the relative safety of our normal cruising grounds in the Apostle Is...

Carl’s weighted halyard messenger begins with a figure-eight knot tied several inches from the end of the line, at top. He then threads steel nuts onto the messenger line to create a weight flexible enough to pass over a sheave, at middle and above. Another knot tied at the end of the messenger keeps the nuts from falling off.

A not-so-nutty way to send a messenger Issue 80 : Sept/Oct 2011 You say you lost an internal halyard? You’re scratching your head over how to reeve a messenger with which to pull through a replacement...
