For me I have an Exocet Windsup 11'8" which I've had for 6 years. It's designed by former PWA rider Patrice B (just Google) who designed the Kona One but wider and softer rails so early to plane, as fast( maybe lose a little upwind) and easy gybe as Kona.
With a 5 batton 7.5m EOL Freeride sail I've done 27 knots, picks up windswell.
As a SUP it has length to get reasonable flat water speed and in small waves picked up a bump. I've now got a smaller 10 foot lower volume, more rocker and softer rails for better waves

You will see a step tail which for windsurfing on reach in planning conditions just kick up center board and mast close to back of track it will go fast. Unlike old race board where you had to kick up board and move mast back you immediately accelerate into foot straps.
Where I live the predominant wind is offshore and I can launch 500m from home and slog out 300m to wind line or drive 45 minutes each way to sail short board ( which I do when its windy!)
