115L Manta, 7.5 Koncept, 42cm Spitfire

Sailed with 42cm tectonics fin and even though it works fine and shows better speeds than Select 39cm it's so much harder physically to sail with, wears out upper body and thighs much quicker. 

Put both GT-31 and GW-60 in a waterproof bag on my arm this time. Started both at the same time, deleted previous logs and after the first run watch was showing 42.99 kts max without getting under the water. When uploaded to the latest version GPS Results the numbers were really close even a bit lower (0.1 kt on 2 sec and 10 sec max) on the watch, although while sailing the watch was always about 0.4 kt higher for both 2 and 10 sec max. And I couldn't find that 42.99 spike anywhere. KA72 also showed pretty close numbers this time, similar to GPS Results.
