Systems & Propulsion

In the article “Is All-Electric Propulsion Practical on Small Sailboats?” we explored the current state of technology for all-electric marine propulsion. We concluded that...

The 18th century was the age of sail. The 19th century saw the introduction of steam propulsion and the 20th century witnessed the introduction...

Reverse-osmosis, DC-powered watermakers have been available for use aboard mid-sized cruising sailboats for years, but thanks to new technology, they just keep getting better. Todays units are more efficient, reasonably compact, and in many cases, modular in design. Practical Sailor recently tested two popular models-new Ventura 200T from Spectra Watermakers Inc. and Racor Village Marines Little Wonder (LWM-145)-and rated them for water and construction quality, noise, power consumption, and ease of installation and maintenance. The review also discusses the pros/cons of installing a watermaker on a sailboat, installation and maintenance tips, and whether a watermaker is right for you.

Connecting two wires is simple; use a properly sized crimp butt connector with a ratchet crimper, and finish with adhesive-lined heat shrink in damp,...

A sailboat’s steering system also plays a vital role in safety at sea. The failure of any key component can jeopardize boat handling and...

Winter temperatures are challenging for year-round sailors. Appropriate clothing is vital, including waterproof socks, layering for the legs and midsection, finishing off with a...

Here's a combination that will give you a decided advantage the next time you need to change a waterpump impeller. In difficult circumstances, the time saved could mean a lot.

Only boats with inboard engines have stuffing boxes. To locate yours, trace the propeller shaft from the transmission to the point where it exits the hull. Thats where your stuffing box will be (unless you have a newer, dripless style shaft seal installed instead).

Sailors obsess over the health of their engine; it is the heart of the boat (other than the rig, sails, and through-hulls). Failure is inconvenient, expensive, and even dangerous. And sailors love their maintenance, or so it seems. Anything that promises to ease the mind for a few dollars merits investigation.
