Designed around the glance
Readable even at sea.
HullSpeed keeps the primary GPS boat speed number dominant and pushes everything else into quiet supporting positions, for quick wrist checks.
A rolling 5-minute trend chart below the main speed helps you tell at a glance whether trim adjustments are increasing or decreasing your speed.
When using an Apple Watch, your heart rate stays visible at a glance.
Supporting data shows course, compass heading, voyage time, and direction.
HullSpeed works great as an Apple Watch sailing speedometer, and it works well with only an iPhone too. Use Apple Watch when you want to monitor your heart rate.
