Engines and Systems

Deep Blue: a bigger electric outboard

In early 2012, SAIL gave a Pittman Innovation Award to Torqeedo for its continuing efforts to refine its electric outboard motors over the years.

Gear: Grey-Beard Pumps

Oil changes are vital to keeping your engine running its best but oil transfer pumps can be tough to use. Grey Beard Pumps utilizes medical device technology to create a pump that claims to be trouble-free

Portable Nav Lights

Norway’s Navisafe offers a number of portable battery-powered U.S. Coast Guard-approved running lights, including a white standard navigation light, a Navi TriColor light and, most recently, the Navi rescue light.

Flexible Solar Panels

Maintenance-free and weatherproof, Ganz Eco-energy semi-flexible solar panels provide clean, quiet, reliable power offshore

Gear: Quality Impellers Increase Engine Efficiency

High-quality, long-lasting impellers from JMP are manufactured from a mix of different rubbers and include a surface coating that decreases wear and tear for longer use.Tested by the U.S. Navy, the impellers help keep marine engines working at their highest efficiency, even in harsh operating conditions, by ensuring that their pumps are operating correctly.JMP offers flexible

Electric Outboard Motors

This past summer I tested the latest generation of electric outboard motors from Torqeedo. These are much more efficient than traditional electric outboards, but with this advance comes a quantum leap in sophistication and electronic complexity.I find it intriguing that these outboards have been designed by landlubbers. One of the owners of Torqeedo, Dr. Christoph Balin, bought a house on

Condensation Conundrum

Clyde Collins of Seneca Falls, New York, asks:”I’ve moved up from a Catalina 22 to a Bayfield 29 with a 20-gallon diesel fuel tank. I sail on the Finger Lakes of New York and only use about 5 gallons of fuel a summer. My understanding has always been that I should store the boat over winter with a full tank to minimize condensation. But that means I have 15 gallons that

Propellers 101 Page 3

A propeller converts the rotary output of a boat’s engine into an accelerated stream of water. This acceleration creates thrust that pushes the boat through the water. To work efficiently, propellers must be properly matched to their engines and transmissions. Other important factors include the boat’s displacement and waterline length and the clearance between the propeller shaft and the bottom
