Two speed propeller

by Nigel Calder, Posted May 18, 2009
Black clouds bearing cold rain showers are racing across the sky. The VHF radio is broadcasting gale warnings. This is not the day to be testing propellers, but nevertheless we are headed out of a marina near Aarhus, in Denmark, on a Bavaria 42 equipped with a Gori three-bladed folding propeller.The three- and four-bladed Goris are unique in the propeller world. They look much like any

Wi-Fi for Sailors

by David W. Shaw, Posted May 8, 2009
The term Wi-Fi gets bandied about plenty these days. After all, you probably use it to obtain high-speed Internet access at work, in airports and hotels, or at home, and you’ve probably used it on your boat, likely with varying degrees of success. Built-in Wi-Fi hardware in laptops, or PC Wi-Fi-card adapters (802.11 cards), such as those from Linksys, work fine if you’re close

AIS for Sailors

by Peter Nielsen, Posted May 7, 2009
Any sailor who has made extended passages along coastlines or across oceans has had at least a few close callswith big ships whose course and intentions can be difficult to discern until the last minute. The introduction of AIS (Automatic Identification System) has taken a lot of the guesswork (not to mention terror) out of these close-quarters situations. For just a

    Let there be water

    by Peter Nielsen, Posted December 22, 2008
    Of all the upgrades you can lavish on an older boat, few will give you more bang for your buck than a complete overhaul of the fresh-water plumbing system. An improvement in water quality should be immediately apparent; any of the new breed of water pumps will be quieter and less power-hungry than their predecessors, and with a little planning, you can make your boat much more user-friendly both

    Quiet Connector

    My wife, Gail, and I recently installed a new radar antenna on the keel-stepped mast of our Bristol 38.8. The first part of the installation was easy. We mounted the receiver and then, using a weighted string as a messenger, pulled the cables through a small hole in the mast near the unit all the way down to the bottom, The difficult part—figuring out a way to keep the cables from slapping

    Smell. Pong. Effluvium. Whichever way you describe it, the airborne essence emanating from Ostara’s aged sanitation system was highly unpleasant. More than just an odor but thankfully short of a full-blown stench, it permeated the forepeak and almost caused a spousal mutiny during our first weekend aboard. No doubt about it – something had to be done.The sanitation system comprised a
    My brother was hanging upside down, peering through a 9-inch square cutout in a bulkhead at the raw-water pump housing on his 3-cylinder Yanmar marine diesel. “How the heck do you get the impeller out of there?” he asked me.This is a very good question. Removing an impeller is something that should be done on a regular basis; Yanmar recommends replacing the impeller on this particular
