Re: Trailer Sailer Performance
Give up nothing, go wtih a lifting keel instead of swing.
S2 6.9 (22 foot boat).
S2 7.9 (26 foot boat).
Trailer sail and launch like a motorboat (even better than swing keel).
Performance is stellar.
Think its a slow design?
Look at: Left Coast Dart, B25, J70, Melges 24, U20, and dozens other that I can't think of.
Swing keel is slow(er) than fixed, or wing for sure.. but there are better more trailerable designs out there than swing.
But directly answering the question, it can make a huge performance difference, look at ratings for the Catalina 22 swinger versus fin. These are Portsmouth derived ratings.
Catalina 22 (FK, No Spi) 97.1
Catalina 22 (SK/WK, N/Spi) CAT22 96.3
So there would appear to be a significant difference. The Catalina 22 has a fairly large sampling for ratings (due to numbers made).
