With good results and particularly good downwind speed the Skinny one! was a success but in certain extreme conditions up wind and downwind the bow had a tendency to go down .Overall it was possible to get very good speed from this hull but it was always necessary for constant trimming and concentration to get maximum speed.
Lessons learned from this were invaluable in deciding the shape for 2002 and the new mould is essentially a cross between the Skinny One! and the previous standard hull. On the new shape we concentrated on symmetry and combining the best aspects of the two previous shapes to produce a shape that was fast but not temperamental.
Structural Improvements:
Lessons learned from other classes we are involved with have lead us to change the majority of hull ribs to a fully moulded rib. This is a change from foam strips glassed over.
On the 470 due to a much thinner hull laminate thickness foam ribs glassed over inevitably show through on the surface and although this is not such a problem on the Finns thicker laminate over time and in certain conditions the foam ribs do become apparent on the surface.
We have been extremely careful not to change the stiffness of the forward hull and foredeck and all forward ribs and laminate are unchanged.
Local laminate increases particularly around the gunwale of the main deck and under the hiking area give the main deck more stiffness and strength in these areas. |
