I'm not sure of the NM stats as it's my first time using the GPS and software.
Times set in a small bay (100m) which is formed by a headland, at the end of the headland is wrap around swell/chop, and on the inside the wind get dirty as the headland rises.
So not idea for speed runs, but at least enough for shot bursts of speed in the flat area before the wind dies.
40+ knots should be possible here in stronger wind, but not for long distances.
