Frozen Out

by Don Casey, Posted January 19, 2010

Roy Labonte of San Bernardino, California, asks:"The main and jib halyard sheaves on my Islander Freeport 36 are corroded and frozen at the masthead. I freed the pins on the sheaves by knocking them back and forth with a rubber mallet. But I have had no luck freeing the sheaves themselves.

Ralph Furman of Newport Beach, California, asks:"I use wireless sensors aboard my Hunter 45DS to monitor temperatures for my refrigerator, freezer, engine compartment, engine-cooling system and air conditioning.

Smoky Surfaces

S.J. Byrus of Auburn, New Hampshire, asks:"My Bristol 32 was built in 1980 and its hatches are molded fiberglass with gelcoat on the outer edges. The center of the hatch is translucent, so light can pass through.

AIS Anxiety

by Tim Bartlett, Posted December 20, 2009

William Solberg of Los Angeles, California, asks:"You have done a great job keeping us up to date on the new AIS technology, but I’m wondering whether it is better to use a masthead antenna with a splitter or a dedicated antenna mounted aft on the rail.

Robert Hall of Stuart, Florida, asks:"My stereo system works perfectly, but at a certain time in the afternoon, when the volume is set low, I can hear an annoying tic-tic-tic sound in the speakers when I’m listening to my classical-music station. When I turn the volume up a little the sound goes away. Someone told me it was because I had a cheap audio system so I went out

Scruffy Smells

by Don Casey, Posted November 20, 2009

Cat Fraser of Colchester, Vermont, asks:"How do I get rid of what I call 'boat smell?' I’ve tried baking soda, a dish of vinegar and many commercial products. Somebody told me that coffee grounds are the way to go. A friend of mine made her husband change to stainless steel water tanks, but that’s not an option here." Don Casey replies:To

In the Zincerator

by Nigel Calder, Posted November 20, 2009

Allen Judy of Whortonsville, North Carolina, asks:"My boatyard technician tells me that there is such a thing as being “over-zinc’d” and that there is an optimum amount of zinc anode to install on any a given boat. He says this has something to do with an electrical field imbalance and that it is best is to have just enough imbalance to sacrifice the zinc that is in place.

Luff Considerations

by Win Fowler, Posted November 15, 2009

Bob Boller of Benicia, Califonia, asks: "I have three headsails for my 1980 Catalina 30 and their LPs are 85, 110 and 150. As it does on many cruising boats, the bow pulpit interferes with the lower portion of the sails, especially the smaller two. What do you think about slightly raising the tacks of the sails up the forestay? What effect will that have on the performance

Janet Hartman of Beaufort, North Carolina, asks:"Recently I contacted the National Ocean Survey (NOS) to ask whether the authorized clearances for overhead cables shown on their charts include the extra distance needed to avoid arcing. I received an email from nautical.charting@noaa.gov stating 'The ‘authorized clearance’ for an overhead power cable does not include the

Clear Eyes

Robert Miller of Port Isabelle, Texas, asks:"If I don’t bother to clean my radome when it gets covered with dried salt spray, dirt and dust, will that have any effect on the efficiency of my marine radar antenna?" Gordon West replies:It could be significant, which is why you should always keep your radome as clean as possible. Soot, dust,
