1997 – Sunseeker Hawk 31 – Completely refitted throughout – Stunning Boat

This Sunseeker Hawk 31 is exceptional. She is a 1997 model year boat but there is nothing 1997 about her aside from the hull and windows! She has spent 8 years undergoing the most comprehensive refit we have ever seen and the results are simply breathtaking. The owner has kindly supplied us with as comprehensive list as he is able to complete and we have pleasure in including this below.

There is a walkthrough tour and drone video that accompanies this listing. We cannot stress how special this boat is and know there is no finer refitted classic Sunseeker in existence… she is a very unique and collectable boat.

PERFORMANCE

Max speed: 42 knots

Key features of repower:

The modern 3.0 V6 Diesels offer uncompromised punchy power with unrivalled fuel efficiency.

Maintaining smooth and quiet control at low speeds via the flyby wire controls, with a subtle Vee engine burble from the drive exit exhausts when idling, it is hard to believe she is diesel powered, with the absence of the 1990’s diesel smoke, as seen with original KAD42 examples.

Accelerating without delay when throttled up the engines offer RIB-like performance, perfectly accompanying the Don Shead Deep-Vee hull beneath.

With plenty of background turbo/induction noises but still maintaining the smoothness on offer of the V6 common rail engines, the boat is an exciting mix of modern performance, efficiency and retro-nostalgic Sunseeker handling and ride experience.
