The O2 Freerace enjoys direct response to trim.
At minimum trim the O2 Freerace powers from head to foot and is alive with easy, breathing power.
Tug its adjustable outhaul, and the forward-oriented shaping works with its seven battens (five tubed) to maintain incredible Freerace upper-end.
At maximum trim the O2 Freerace body is slim & stable with an open, harmonically twisting leech… top end speed easily comparable to full-on cammed racing sails.

The O2 Freerace Concept is planning power, handling ease and upper end stability with the broadest possible wind range, all in an easy to rig package... the progressive answer for light wind windsurfing performance.
