I'm a member of a thriving RC sailing group at Whitefriars SC in the Cotswolds. We have a fleet of 15 IOMs that race every Tuesday during the year as well as a similar sized fleet of DF95 that race on a Monday...
We are working on several fin designs. Parallel, tapered and wine glass forms. All use the same head fitting and will be available very shortly. As fins are critical to the performance of any boat we are now supplying Dave Creed fins and rudders as an option.
