According to a press release issued yesterday from Kannad Marine, the FCC has approved for sale in the U.S. Kannads SafeLink R10 SRS, the worlds first personal Automatic Identification System (AIS) device designed to be worn by individuals and activated to assist in man overboard recovery. Worn on a life jacket and activated by simply sliding off the safety tab and lifting an arming cap to deploy the antenna, this unique product sends structured alert messages, GPS position, and a special identity code directly to AIS receivers within (approximately) a four-mile radius.

It's just a few weeks until summer begins, and our hopes and prayers for a safe 2012 sailing season in North America have already been shattered. Five sailors were washed overboard and died in Saturdays Farallones Race, sponsored by the San Francisco Yacht Club. This was an experienced crew, which included several sailors with close ties to the San Francisco Yacht Clubthe home club to many longtime Practical Sailor readers.
According to news accounts, the Sydney 38 Low Speed Chase was struck by a breaking wave while rounding South Farallon Island, one of a group of islands outside San Francisco Bay that serves as a rounding mark in the 48-mile race.

Who can you trust? Youd think that the Internet explosion and the current boom in blogging and social media would make life easier for the wannabe cruising sailor looking for information on boats, equipment, and cruising in general. But when you start peeling back the layers of informationeverything from bulletin boards to blogs to e-zinesyou find that the Web is rife with contradictions, bad advice, and now, some contemptible stealth marketing.

Were just wrapping up our testing of the new e7 MFD from Raymarine, which we ran side-by-side with the Garmin 740s, one of our favorites in our recent comparison of small chartplotter-sounders. The e7 was the most interesting electronic gizmo we saw at this years Miami Boat Show, the annual debutante ball for manufacturers to unveil their newest creations to the public. The company calls it a hybrid display, using both a

The government already has a variety of ways to track our comings and goings, and I suppose I can learn to live with these. But my boat always has been a more sacred and personal space. As I reflected on a future when a person can no longer step aboard his sailboat and fall off the map, I began to wonder whether this new floating creation, forever held in the gaze of the state, will even qualify as a boat.

Has one of the world's most important suppliers of safety tethers for commercial, rescue, and military markets solved many of the problems faced by sailors today? PS Editor Darrell Nicholson talks about safety-tether release lanyards and how marine manufacturers and non-marine manufacturers approach the design challenges associated with this component.

Weve received some good suggestions from readers in response to my editorial in the March issue of Practical Sailor that described our tether and harness design project. Similar to what we did with toddler life jackets back in 2007, the plan is to solicit input from experts in the field, other sailors, and PS readers to try to come up with an improved design for inflatable PFD/harnesses. Because the tether is such an integral part of the PFD/harness when sailing offshore, we plan to work on improved tether designs as well.

I usually dont get too excited about the tricked-out space ships circling the globe in the Volvo Ocean Race, but when I heard the race fleet was split in half, with three of the Volvo 70s planning to weave through the Solomon Islands, my interest was piqued. While the images of these thoroughbred machines racing down the long swells of the bottom of the planet are impressive, the idea of threading through an area of poorly charted reefs, jungle islands, and notoriously squally weather in the darkness presented a tantalizing new twist.

While the ethanol problem has brought a mountain of headaches to boaters, it has ignited a booming trade in fuel additives. At the recent Miami boat show, I heard Gerald Nessenson, president of ValvTect Petroleum Products, talk about the state of the finished fuel-additive industry and what established companies such as his are trying to do to fend off what he feels are unsupportable claims by small upstart companies.

They say a photo is worth 1,000 words, and this one certainly says a lot. On our way to a very serious study of hose clamps at the Miami International Boat Show, the nice sales ladies at the booth of some nameless speedboat showed their appreciation for Capt. Frank Lanier, a retired Coast Guard officer and one of our contributors. It is a standard boat show ploy: Beautiful girls attract men (even those as high-minded as Capt. Lanier) and men buy boats. For many complex reasons (including the fact that Frank's incredibly supportive wife might one day stumble on this blog post), I hesitated to publish this photo. But it serves to illustrate a point that struck me at this years Miami show . . .

More affordable electronic man-overboard tracking technology is on the way. The US-based Radio Technical Commission for Maritime Services has just completed a new standard for man-overboard beacons using Digital Selective Calling (DSC) and/or Automatic Identification System (AIS). According to a news release from the RTCM, the standard requires MOB beacons using DSC and sending "open loop" messages (i.e. standard all-ships distress calls) to be fitted with a GPS and a DSC channel transceiver. The GPS automatically inserts a position in the DSC (and AIS) call, making it easier for boats to locate and recover a crew member who has fallen overboard.

Weve got so many tests in the air, Im afraid to open my inbox these days, for fear that one of our testers has again spiraled off into the deep end of data collection. This, you see, is the greatest challenge we face. So consumed by their mission, our testers like to pick up every detour and follow it to its end, wherever it may lead. Three-week tests drag on for years, with the final results forever lying tantalizingly out of reach. So where are the detours leading these days? Heres a sampling of whats ahead.

There are very few times when the door to my office is closed. Bottom paint rating tabulation time is one of them. For the past week, Ive been poring over bottom paint data collected earlier this month: three Excel tables representing more than 300 data points. Although mammoth data tables are not what drew me into this business, the bottom paint program is still one of my favorite projects. Ive spent enough time scrubbing, scraping, and painting to appreciate the importance of what we do.

Practical Sailor reader Duncan Hood wrote us last week, asking about engine room noise insulation and prompting me to dive into our files to find our last test. Its been over a decade, so were due for another round of testing, but much of the information in our last report is still helpful. Many of the players are the same, and one of the most prominent players in our last test, Soundown, is still regarded as a leader in the field.
For those like Hood who are contemplating ways to silence the engine, the following excerpt from that article offers some general guidance.

In the February 2012 issue, we tested two holding tanksone from Trionic and one from SeaLand. Both tanks slightly leaked water while under pressure. The leaks were very small and occurred at top-mounted fittings that were supplied separately with the tanks and were installed by our tester according to the manufacturers instructions. After the storys publication, SeaLand informed us that tank that we tested and recommended was not the most current model.
