I am a big fan of Polar watches due to their accuracy in heart rate monitoring and GPS technology. Training sailors with Polar watches has advantages and disadvantages. I would like to start a petition to Polar to improve their watches and build the ultimate seaman watch. So far I have come up with these;
1) Must be able to use GPS to show boat speed in knots in real time.
2) Must be able to select Speed Over Ground for marine navigational purposes.
3) Must have compass function.
4) Must have sailing timer which countdown and beeps from 5mins, 4mins, 1min, 0min.
5) Must have depth gauge for divers.
6) Must have tide graph and moon phase.
7) Must withstand the harsh elements of the sea.
Anything else I am missing from the list? Polar already has the technology and just need to tweak their products to make this work.
I believe there’s also a way to link a Garmin watch with a Garmin chart plotter and get data from the boat’s instruments, but I’m not sure how many apps can leverage that. I think most racing apps just rely on the watch’s GPS, which means you only get COG/SOG and the app has to calculate TWD based on tacking angles or something.
so, ideally I'd like a watch with 150-200hrs battery life to suit long offshore races
