Hi there,
while still trying to shape daggerboards, I "heard" that I could use the Nacra F18 daggerboards on my Sol Cat 18.

As I don't have any of those available near me, I would appreciate any expertise on this.

I made a "sample" for my Sol Cat out of foam, that at least fits into the pontoon slots.
Its a little less then 12.1/2 inches at the top, a little less then 11 1/2 on the bottom, 39 inches long (I looked at some pictures to get that length. The daggerboard at many cats seem to "stick out" on the bottom the same length as the rudders going down.) Its a little less than 3/4 inch at the thickest part, only 1/4 at the small end (back).

The sample fits in "snuggly", so could obviuosly be a little smaller in size.

How's that in comparison the Nacra F18 ?

I had the cat in the water today for the 1. time, but without daggerboards I was just drifting to leeward

Thanks and have a great holiday.

Michael
