Overview

The Interboat Intender 850 builds on the success of the popular Intender 820, offering increased space, comfort, and flexibility for owners looking to enjoy both inland and sheltered coastal waters.

The layout is designed for relaxed days on the water, with a large aft sun pad, a practical port-side walk-through, and deep, comfortable cockpit seating. The engine is neatly mounted beneath the cockpit floor, maximising usable space on deck and allowing for a well-proportioned forward toilet compartment.

For coastal use, the Intender 850 can be specified with engine options up to 250hp, providing performance of up to 25 knots when conditions allow. The combination of a keel and shaft drive delivers predictable handling and excellent low-speed control, making the boat easy to manage in harbours and marinas while still offering confidence on open stretches of water.

Rated RCD Category C and accommodating up to 10 passengers, the Intender 850 Coastal is well suited to exploring areas such as Chichester Harbour or enjoying the Solent on a calm day, while remaining equally at home on rivers and estuaries.

10 year hull warranty
