The ISO 12215 standard gives designers and builders a detailed baseline for scantlings and specific guidance regarding material selection, workshop practices and structural details pertaining to hulls, decks, rudders and rigging for mono and multihulls. These scantling guidelines relate to specific skin pressures on the hull and stresses and strains that if not appropriately addressed can affect delamination and lead to structural failures. The codes are a complex amalgamation of data, but the University of Southamptons Wolfson Unit has recently developed a software program called HullScant that makes ISO compliance for builders and designers easier to work with.
There are VHFs on the market that use Bluetooth to pair with compatible headsets, but we don't know whether they use the same Bluetooth protocol as the Oticon streaming device that you have. A call to Oticon likely would confirm. The only Bluetooth-ready VHFs weve come across are the Standard Horizons fixed-mount Quantum GX5500S (PS Best Choice, October 2009) and its HX760S handheld (PS July 2009), which has been discontinued.
There is magic in sailing. What is sometimes harder to grasp is the magic in boats. But it is there. It is undeniably there. It is there when first you step aboard and feel the boat come alive underfoot. It is there when the sails fill and quiet as you come out of the eye of the wind. And it is there when you take the tiller under a dome of stars and realize youre connected to something much, much bigger than a rudder. There IT is, as persistent as a heartbeat: a pulse, a throb, a jolt of I-cannot-explain-this magic.
This fast and handsome cruiser/racer from the 1970s is an excellent example of what made C&C Yachts such a successful company. C&C stands for George Cuthbertson & George Cassian, the design team that, in 1969, joined in partnership with Belleville Marine Yard, Hinterhoeller Ltd. and Bruckmann Manufacturing to form C&C Yachts. The company had a tumultuous history, from growing to capture an estimated 20 percent of the U.S. market during the 1970s, to suffering a devastating fire in 1994 while owned by Hong Kong businessmen Anthony Koo and Frank Chow of Wa Kwang Shipping. Along the way, they built a tremendous number of boats, not only in the racer/cruiser genre that was their mtier, but also the Landfall cruiser line, and a few oddballs such as the 1977 Mega 30 with a retractable fin keel; the Mega 30 and a handful of others simply bombed.
Following graduation from California State Polytechnic University, naval architect Carl Schumacher spent four years working as an apprentice with Gary Mull before opening his own shop in Alameda, California, in 1977. He has since designed 37 boats ranging in size from one tonners to 50-foot world cruisers, participated in the design of the front-ruddered Americas Cup boat skippered by Tom Blackaller in the 1987 trials, and most recently designed the Alerion Express boats, which are being constructed at TPI Composites, Inc.
The Norseboat 21.5 is designed for the small-boat adventurer who likes to travel with as few mechanical encumbrances as possible. Its light weight makes it easy to tow with a mid-size car, and its shallow draft (less than 18 inches) opens up remote coastal cruising areas that bigger boats can’t reach. For those who like to explore by backpacking, bicycle, or canoe, the boat is a logical upgrade. But you don’t need a $35,000 Norseboat 21.5 to poke around the many outstanding small-boat cruising areas. Some sailors might be happier to have a renovated 38-year-old Venture 21, like the one we reviewed in the April 2011 issue, and put the $30,000 they’d save toward the next adventure. However, several important features—a contemporary, sea-kindly underbody, high-quality construction, good fit and finish, and a sensible centerboard arrangement—put the Norseboat head and shoulders above vintage trailer-sailers.
Practical Sailor tested a field of 10 tubs of paste waxes for ease of application, gloss, texture, finish, and price. Most of the products did a fairly good job of producing initial shine. The two waxes with the most glossy fiberglass test patch were not the easiest to apply nor were they the least expensive. The boat wax test included marine paste waxes and car waxes-some with carnauba-from Meguiars, Turtle Wax, 3M, Collinite, Kit, Mothers, Nu-Finish, and Star brite. You need only dip a toe into this topic to realize that there are almost as many recipes for a glossy hull as there are sailors whod rather do anything than wax their hull. As long as marketeers keep alive our hopes for a glossy finish that will last forever, there will be people who will plunk down hard-earned money for the latest and greatest gelcoat elixir. We generally define gloss as being the surface ability to reflect light. Gloss, along with ease of application and the ability to repel dirt and water, are the features that Practical Sailor focused on for this report (see "How We Tested," page 32).
