Range

What is yacht range?

Range is the distance a yacht can travel on one full tank of fuel at a stated cruising speed, expressed in nautical miles (nm). A figure without its paired speed is meaningless: the same yacht might cover 6,000nm at 10 knots and barely 1,500nm at 20 knots.

Range is normally quoted at the yacht's most efficient cruising speed, which sits well below maximum speed. For a displacement motor yacht, that economical speed is typically 10-14 knots; for a planing yacht, 22-26 knots. Moving from displacement to planing speed can multiply fuel consumption per nautical mile by three to five times.

Indicative figures:

• Classic 50m+ displacement motor yacht: 4,000-7,000nm at 12-14 knots. Comfortably crosses the Atlantic with reserve.
• 40-50m planing motor yacht: 1,500-3,000nm at 22-26 knots. Coastal and short-passage profile.
• Explorer / expedition yacht: 6,000-10,000nm or more at 9-11 knots. Designed for unsupported ocean crossings.

Range derives from fuel capacity, displacement, hull resistance and propulsion efficiency, typically with a 10% reserve built in.

Why it matters for yacht owners

Range, paired with cruising speed, is the single most honest indicator of where a yacht can actually go. A buyer comparing a 45m planing yacht with 2,500nm at 24 knots against a 45m displacement yacht with 5,500nm at 12 knots is choosing between two entirely different cruising profiles: Mediterranean coastal hopping versus genuine ocean capability.

For owners planning transatlantic crossings or remote itineraries, range determines whether the yacht crosses on her own bottom or is shipped on a heavy-lift vessel. Always read the figure with its stated speed.

Key facts

• Range is always expressed in nautical miles at a stated cruising speed; the speed pairing is non-negotiable.
• Classic 50m+ displacement motor yachts typically achieve 4,000-7,000nm at 12-14 knots.
• 40-50m planing motor yachts typically achieve 1,500-3,000nm at 22-26 knots.
• Explorer and expedition yachts are designed for 6,000-10,000nm or more at 9-11 knots.
• Fuel burn rises non-linearly with speed; planing speeds can increase consumption per nm by 300-500%.
• Range is calculated from fuel capacity, hull resistance, displacement and engine SFC, normally with a 10% reserve.
• The Atlantic Rally for Cruisers (ARC) route Las Palmas to Saint Lucia is approximately 2,700nm.
• Range degrades in head seas, strong currents and at full-load displacement.
