Can Diesel Damage Fuel Lines?

Given the tiny amount of fuel it takes to clear the jetty and hoist sail, our 50-gallon fuel supply can last, quite literally, for years. It certainly lasts through the winter, and all the while, we worry that sludge is growing.

Fuel Filtering Systems

I am the new owner of a 1979 Tayana Vancouver 42 with a Volvo D2-55B diesel engine installed in 2004. Fuel is held in two 80-gallon fiberglass tanks and filtered via a Racor 500 utilizing No. 2010 filters. I use 2-micron filters and Biobor JF Anti-Fungal additive. Despite fuel scrubbings, I continue to have to change primary fuel filters with each fueling. I have been told that I don't need as fine a filter as the 2-micron, but I don't want to risk increased maintenance of the diesel. What do you recommend?

Soundown and Hough Put a Lid on Engine Noise

Engines make noise. Crew-especially when theyre trying to hold a conversation, sleep, or just relax-don't like noise. The solution? Isolate the crew from the engine noise and vibration. In this update of our May 1, 1993 report, 10 sound-attenuating products are tested and ranked.

Marine Fuel Filter Test

Diesel engines have evolved into incredibly reliable power sources. Change the oil, mind the charging system and batteries, and most importantly, always give them clean fuel. First there is diesel bug. Bacteria and fungus (not algae-that is incorrect nomenclature) can infect the tank, feeding on the diesel and producing volumes of tank-, line-, and filter-clogging biomass with the consistency of snot. It can be prevented by the regular use of biocides (see PS August 2013), but…

Oil and Fuel Filters

One Practical Sailor contributor, the manager of a custom boatbuilding and repair/refit yard, had this reply: "Not all filters are created equally: There are differences from filter to filter. We see no problem using after-market filters whose reputations are proven: brand names such as Fram (makes filters for Honda, Chrysler, and others), NAPA, Wix (Wix actually manufactures NAPAs Silver and Gold series filters), Fleetguard (owned by Cummins Filtration), and Baldwin to name a few.

Prop and Shaft Check

A vessels drive train is typically defined as the components between the engine transmission coupling and the bitter end of the propeller shaft. For traditional drive trains, this includes the propeller, shaft, cutless bearing and packing gland, although the list could also be expanded to encompass ancillary items such as the rudder, engine mounts, and engine bedworks. Heres a look at two major drive train components you should know and what to look for when inspecting each. Next month well look at the components inside the boat-stuffing box, shaft, and coupler.

Reducing Engine Room Noise

If your sailing partner complains about a noise that doesn't really bother you, it might not necessarily something that they can just "get used to." You will have to address it through active sound reduction measures.

Rhumb Lines — Getting a Fix on Reality

It was mid-July 1990 on the Caicos Banks, a stretch of shallow, gin-clear water extending for about 70 miles east to west in the Turks and Caicos Islands. Along with a dozen other cruisers whod chosen to thumb our noses at hurricane season (ah, those were simpler times), we were pausing in Providenciales before heading south. …

The Ins and Outs of Aftermarket Bowsprits for Light-air Sails

A salty Kiwi named Ross Norgrove once said that the most important tool for the owner of a wooden yawl adorned with a bowsprit is a sharp ax. To some degree, his witty comment holds true for contemporary sailors contemplating a mini-bowsprit.
