Used the 5.1m tr-4 yesterday in choppy and gusty conditions. Wind was 15 - 23 knots and the sail was great. Gps max 36 knots. Heaps of power, fast and looked real nice. Used on isonic 94 with select 31cm sl7 and sail was awesome. Can't wait to get this sail on isonic 50 in some real speed conditions.
With the 15 -23 knots wind I'm interested in at what point you can get the board up and planing freely with just 5.1 sqm. I'm 90kg and seem to need 20knots with a 6m to get going or 7.5m at 15kn tho thats using non cam sails Cheers Phil
As Nebbian said you need to bag them out. I wouldn't have usually chosen to ride the 5.1 and would have been on 5.8 but because the sail is new i gave it a go. I was very impressed with the early planing of a 5.1m sail too.
