Description

The Sunline 31 is a versatile, fun and sensible family cruiser. British-built by Discovery Marine, the Sunline 31 packs a genuinely surprising amount of boat into her 33 feet — and with a draft of under a metre, she's tailor-made for the inland water ways or coastal cruising. She will cruise comfortably at 20-22kts all day and will top out at 26-27kts. A massive benefit of the 1.7dti is consumption, she will use approximately 24 litres per hour at 20 kts.

Benefiting from a comprehensive mechanical overhaul and service in July 2026.
