Q&A – Frequently Asked Questions
What is the deep cockpit for?
It lowers the center of gravity and increases control in gybes and tacks . At full speed, it helps balance and reduces the sail's leverage, allowing for more precise support.
How do cutouts help with foil starts?
Deep cutouts reduce wetted surface area and drag on takeoff; the secondary step keeps friction low on touchdowns, promoting immediate relaunch.
What fin box do you use?
All sizes feature a Deep Tuttle
Which size do I choose based on my weight?
As a general rule: 73 cm up to ~105 kg, 79 cm up to ~95 kg, 85/91 cm up to ~85 kg. Also consider sail, foil, and spot: for choppy water and larger foils, a wider width helps.
