Lot of data based on one regatta here, that was sailed in mostly light airs and the single-wire in-between conditions where the deep boards have proven to be most effective. It's hard to justify $2400 for a pair of long boards when the existing boards are already 5 long. I would have an easier time with it if I could still use the short boards but on the Infusion they went narrower chord on the long boards so its not much of an option. West River is awful shallow and we touch bottom once a week usually with the short N20 boards...digging a $1200 board in the muck isn't my idea of fun.
