Volvo Ocean Race Yacht Drawings
By Francois Chevalier
François Chevalier's remarkable article provides the lines drawings of the Volvo Ocean Race boats, including those racing the final leg of the 2011-2012 race underway as this is written!
To create these lines plans of the Volvo Ocean Race boats, which I drew on tracing paper, I examined the hulls in build or ex-works, using their cradles as a source at times, and all the while keeping in mind the personalities and intentions of the yacht designers who had created them, and especially in strict observation of the relevant rating rules. Thus I was able to draw them fairly accurately. As soon as the sailing boats received their keels, rudders and centerboards, I was able to finalize the plans for the 2001, 2005 and 2011 editions of the Volvo Ocean Race.
Post-Capsize Safety Lessons
By Jonathan Seymour
On February 17, 2010, at approximately 14:23 local time, the sail training barquentine Concordia was knocked down and rapidly capsized after encountering a squall off the coast of Brazil. All 64 crew, faculty and students successfully abandoned the vessel into life rafts and were rescued two days later by two merchant vessels and taken to Rio de Janeiro.
But the evidence available to the TSB, which included video and photographs, along with statements from those on deck at the time, suggested that the winds never exceeded Beaufort force 7-weather conditions that Concordia had encountered many times in its twenty years of ocean voyaging. Satellite imagery was obtained and weather experts were consulted. In comparison to thunderstorms known to have produced microbursts, it was clear that this one was not sufficiently formed to do so.
So what happened?
What Constitutes Ignition Protection?
By Ed Sherman
I received a query the other day asking about a really important issue related to marine electrical system component ratings for ignition protection. This is a common question and it's important because you don't want your boat to end up looking like the one in the photo below.
