Inside Practical Sailor

Last year, multi-national chemical company BASF decided it would not renew its U.S. license for the pesticide Irgarol. A common additive to copper-based paints, Irgarol helps prevent the growth of algae and other soft growth. Bottom paints containing Irgarol are priced around $30 higher than similar formulas without the additive. If you are interested in a slime-resistant ablative paint, be sure to confirm that Irgarol is still an ingredient before plunking down the extra cash.

The oceanic equivalent of implacable in-laws, the barnacles addled me to no end. Do they ever stop eating? Do they ever sleep? Why wont they leave my boat alone? Their unrelenting click, click, clicks on the hull kept me up at night. An obsession bordering on madness set in. My only comfort was that barnacles on the brain can have interesting side effects, like an idea that changes our view of the world.

In my own experience, Ive found that I rarely can match the manufacturers coverage estimates using a 3/8-inch nap roller cover, so for this project we decided to do a comparison. One section of the boat would be painted with a foam, solvent-resistant hot-dog or sausage roller cover, a technique that has worked for me in the past. The roller, more commonly used for topside finishes, soaks up far less paint than a conventional, 3/8-inch cover. An adjacent section would be painted using a conventional roller.

This summer, the once lovely Oyster 825 was hauled from the water with its keel missing and a large chunk of skin laminate peeled back. Another casualty in a disturbing trend. I wrote a lengthy post on the subject of keels last year, and technical editor Ralph Naranjo discussed the topic in his report Rethinking Hull Structure in the February 2015 issue of Practical Sailor.

Our recent report on synthetic-teak decking options (see PS December 2015) raised a bit of a ruckus among the contenders in what is an extremely competitive market. The main bone of contention was our reported temperatures of the various materials after they were left in the sun. Several manufacturers contended that the temperatures we listed in the table accompanying the article were not consistent with their own findings.

The freeze-thaw cycle can also break the bond between the fiberglass and the core, further weakening the deck structure and introducing new problems. In a worst-case scenario, you return to your boat in the spring and find bubbles, bulges, and cracked gelcoat or fiberglass where water has pooled and frozen, pushing your deck's outer skin upward.

In part one of our two-part test of five and six-horsepower engines in the upcoming January issue of Practical Sailor, we take a second look at portable electric motors. Our interest in modern portable electric propulsion dates back to 2004, when then editor Doug Logan began to lose faith in the two-stroke outboard on his Boston Whaler. While awaiting the prognosis on his unresponsive 15-horsepower Evinrude, he bought a Minn Kota Riptide 55 trolling motor.

Two stories in the upcoming December issue-installing a fireplace and sealing portlights and hatches-had me pondering the challenges of a winter afloat. But what literally raised goose bumps were images sent to us by Jimmy Cornell, whose popular cruising rallies and books have inspired countless dreams of sailing around the world.

The more controversial-in my mind-element of open-source software is how our navigation data is used. The success of open-source software depends on the willingness of sailors to share data via the cloud. Were told, of course, that this is anonymous meta-data (the sort of non-identifying data with that the National Security Administration scrapes from phone records), and that the user can control which data he shares. Most of us are already sharing all kinds of information with various smart-phone apps, so this is nothing new. Still, I worry.

I loathe thee for your lovely teak decks, prone to leaking, hot to touch in the tropics, and forever accumulating dirt. I loathe thee for thy alluring bowsprit, a precarious perch where no man with two hip replacements should ever be. I loathe thee for thy water tank sloshing in the bow, turning thee into a teeter-totter when the mildest swell rolls into the bay.
