Designed around the glance

Readable before the next wave hits.

HullSpeed keeps the primary number dominant and pushes everything else into quiet supporting positions, so a wrist check stays a wrist check.

Watch first

Start a voyage from Apple Watch and keep speed, course, elapsed time, distance, and heart rate close to hand.

Trend aware

See whether a trim change, gust, or course adjustment is helping without digging through a dashboard.

Phone ready

Live Activity support keeps speed visible on iPhone when your wrist is not the easiest place to look.
