RE: Spray rails on Supercat 17
Posted: October 9th, 2017, 5:27 pm
Dear All,
After 3 years of happy sailing I am in the process of fairing and re-gelcoating of my 1983 Supercat 17. There is a pretty substantial amount of work as it has developed pretty big "waves" on the hull surfaces between bulkheads over the years (bought it this way). As the work will continue for a few months through the winter I was thinking that maybe it is the right time to add the spray rails (analogous to the ones used on Hobie Wild Cat) provided it is worth the effort.
So my question this:
Did anybody tried or thought about using such spray rails and if yes are there any recommendations or thoughts about the width , height and longitudinal position of such spray rails?
It seems that if they really work (the following reference claims they reduce the frictional resistance by ~12% at 20 knots based on tank testing of sailing cats: http://vm2330.sgvps.net/~syrftest/image ... 094246.pdf ) then the Supercat/ARC would benefit them most due to the hull shape.
Besides they look cool...
Best Regards,
Alex
