A first correlation between Garmin Homeport and Google Earth for a Shark Point to Nest Key route went as expected: GE showed I had Garmin routed onto a mile long sandbar ! hahahahwhat ?
Birdseye GPS could be useful.
Go thru GE before paddling seeing the seascape in more totality than 1.5 feet up.
Another NW wind then E wind for this weekend, 15 knots with 1 foot seas and an outgoing tide from Nest Key.
The tide divisor may be the Shark Point area.
