Fun session that got faster as I tuned my  in 6.6 again (its been a couple of months from last use).

Nelson Haven - low tide. Wind N 15 to 25knots, then NNE of same strength, then NE and was too gusty to really use. 

Ka Koncept 6.6, IS87, Tribal27, GW52

PB for me on the 6.6. Harness lines now 28 (down from 30) and felt good. Set 4.5 and 8 marks on the boom which was 192 long. Extention 16cm and 1.5 fingers space pulley to pulley. Boom height 0.5cm down from middle. Mast base at rear so plate was covering the slot/hole.
