I once asked Rob Ball about that flat area of my 34R, because it would slam when crossing a wave. He said that feature was proven to be fast in IOR designs and even though the 1990 34/36R, 34/36+, 34/36XL series was designed for IMS, he incorporated it into this hull. He told me it wouldn't slam when sailing, or when heeled because the hull has a vee on either side of the flat, so it acts like a keel when heeled. I've learned to avoid the slam by sailing more, or motorsailing, or motoring thru chop or crossing waves at an angle. I've since seen that flat section on many other brand racers.
The newest racing sailboat designs (like C&C 30 and Redline 41) however have eliptical cross sections, like a canoe, bow to stern. Have you seen the chines on the Volvo Ocean 65's this year?

I don't ever recall getting this 34R to surf.....now we rarely wound this boat up to its full potential unless we had a John Roy on board for a race and even then I don't recall surfing.

The folklore says it's supposed to be a planing section to help support nose when running the Spin and keep the bow from "diggin'in" / surf the backside of bigger waves.. The waves on the lake are not big enough to surf / my spin is not quite ready yet. I can't speak from experience. Perhaps Chuck S can comment on his experience with his 34 R surfing waves off the coast of Atlantic City? I did miss an opportunity to test the fast stuff this saturday, winds were in excess of 30 knots and the weather was gorgeous. I did not have a crew so I watched-it from the dock as I was doing some needed topsides and decks cleaning / waxing.. -Francois Rivard 1990 34+ "Take Five" Lake Lanier, Georgia _______________________________________________ This List is provided by the C&C Photo Album Email address: CnC-List@cnc-list.com To change your list preferences, including unsubscribing -- go bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com _______________________________________________ This List is provided by the C&C Photo Album Email address: CnC-List@cnc-list.com To change your list preferences, including unsubscribing -- go bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com
