Carbon is a bit misleading since it is not a carbon boat but one where carbon is used or that or I don't understand what is "carbon fiber reinforced Vinylester" . I mean Vinylester is the resin and I don't know what is reinforced, certainly not the carbon, or the vinylester. Maybe glass fibers reinforced with carbon fibers? I have already posted about this Arcona here: http://interestingsailboats.blogspot.pt/2015/10/arcona-465-carbon-great-performance.html
And that's about what I have to say critically about this boat...off course the style as the interior are conservative but that is a personal taste. There is nothing of conservative regarding the sail performance and in what regards stability besides an obviously good one in what regards stiffness and sail power this boat will have a very good final stability due to a big B/D ratio (40%) on a keel with 2.5m of draft (even if not a better performance torpedo keel).
The Arcona 465 Carbon was tested recently by Pip Hare for the magazine Yachting world and she, that is a racing sailor, says only good things about the yacht. No doubt that she knows what she talks about in what regards sailing, but the way she says it, well, it could be better LOL.
