2001 Crowther Osborn 42 Super Shockwave13m

The Osborn 42 Catamaran is a collaborative project between Bruce Osborne and Dave Calvert (Calvert Sail-loft).  The hulls are based on the fast and proven Super Shockwave 42 by legendary multihull designer Lock Crowther of Australia.   Morelli and Melvin (Playstation maxi cat designers) did the structural engineering, and the underwater foils were designed by Bill Roberts (designer of the Supercat and RC27 and 30).

Osborn and Calvert set out to build a cat that could be ultra competitive in open water racing, and cruised in relative comfort.  The builders utilized carbon fiber, epoxy and Corecell construction to make her incredibly light and strong, weighing in around 7,500 lbs.  A 16:1 hull fineness ratio makes her incredibly fast and stable.  With her high-tech construction, deep daggerboards and spade rudders, this cat will outpoint any other cat of similar size to weather.

The vessel was built in Florida by Osborn, a short lived company to build these boats in production and this was the first catamaran built. The construction is epoxy, carbon fiber with close cell foam coring. 

'Green Flash' raced the Miami to Nassau race in '05 and '06, winning both in corrected time and first to finish. Her previous owner reports her top speed was 27 knots in race mode.

Her previous owner of 7 years had taken the boat one step further and had customized her into a true blue water fast cruiser.  Green flash safely cruised from the Gulf Coast of FL, through the South Pacific, Hawaii and now is in Seattle.

In 2017 and 2018 'Green Flash' made quite an impression on the Sound. 

First overall in the Sloop tavern Iceberg Regatta 2018. First in Multihull class  Corinthian Yacht Club Seattle Center Sound Series 2018. First in Multihull class Corinthian Yacht Club of Edmonds Foul Weather Bluff Race 2017 Third in Multihull class Sloop Tavern Blakely Rock Race 2017.

Green flash is a one of a kind catamaran that will appeal to go-fast sailors that prefer boat speed over extravagant interiors.
