Definitely happy to explain the numbers and thanks 🙏 for asking it’s a great question and an important one!

I’m sorry as a sailor all my life I forget that most people have no idea what all this means. And sailing without instruments is a good skill to have 👍

AWS - apparent wind speed

TWD - true wind direction

AWA - apparent wind angle

BSPD - boat speed through the water

TWD - true wind direction

TWS - true wind speed

TWA - true wind angle

It’s important to understand the difference between true/apparent as it’s the difference between the true and the apparent wind. The apparent is what you feel once you start moving the true is what the wind would be if you weren’t moving and stood still.

The faster the boat is the larger the difference between the true and apparent wind angles and speeds will be.

We live onboard and sail a performance trimaran, which is why you see big differences and why our SOG - speed over ground is higher than you’ll likely see on other vessels.

Hope this makes sense, happy sailing ⛵️ 👍
