Every planing hull has two efficient operating modes — and a wasteful zone in between. BlinkYacht captures real consumption data underway and shows you exactly where on the curve you are, in real time.
Physics divides every planing hull's operating range into four distinct zones. Knowing which zone you're in at any moment changes how you run your vessel — and what it costs.
This chart is based on real logged data from a 15.9m planing motor yacht with twin 800hp engines. Move the speed slider to see exactly what each knot costs — and where the efficiency cliff begins.

The fuel logging system is designed to stay completely out of the way while you're helming, then prompt you only when the data is worth capturing.
Most captains know roughly where their hull gets inefficient — but not precisely. The curve tells you the exact speed where fuel consumption jumps. On Oscar Wilde, it's 9.5 knots. Never cruise at 11.
A fouled hull moves the efficiency curve upward on every data point. When spring and autumn curves diverge by more than 15%, it's time for antifouling — not because the calendar says so, but because the data does.
Cannes to Monaco at 8 knots costs €68. At 19 knots, €180 — but saves 52 minutes. At 30 knots, €210 and saves only 14 more minutes. The curve makes this calculation specific to your actual hull, not a generic estimate.
While underway, the app shows a live dot on your efficiency curve. Glance at it and know instantly whether you're in the sweet spot or burning fuel unnecessarily. No mental arithmetic required.
No extra hardware. The fuel efficiency system is part of every BlinkYacht system.
The system does require a subscription to the backend.
