Re: Information while racing around the buoys
1. Boat speed through the water
2. Mounted compass
3. GPS showing SOG and VMG
That's the minimum. Wind speed and direction (true, apparent) are the next step.
Edit: if you're looking for an explination of why you need these, that might be another topic all together...
