2016 Knysna 500 SE boat for sale

Broker Remarks

Impulse 1 is a 2016 Knysna 500SE — a South African-built performance catamaran designed by Angelo Lavranos and offered for sale in very good overall condition. Built to the 500SE specification with an Owner Version layout, she has been exclusively owner-operated, used lightly each summer since 2020, and kept in dry storage over every winter — an ownership pattern that is reflected in the quality of her present condition.

The Knysna 500SE is a thoroughbred cruiser-racer in catamaran form: a long waterline, an efficient rig, and a hull form that rewards the active sailor while remaining comfortable on passage. Impulse 1 has been extensively upgraded in recent years, with a complete NorthSails Norlam sail wardrobe fitted in 2024, a new Profurl NDE2 electric genoa furler in 2025, a Kohler 7kW generator, a 760Ah Mastervolt house bank supported by dual high-output alternators, a 100-litre-per-hour watermaker, and a full Garmin electronics suite. She is ready for extended blue-water passages or extended Mediterranean cruising with very little to do.

BROKER'S REMARKS

Impulse 1 is a well-found performance catamaran that will appeal to a buyer who wants a capable, well-equipped bluewater yacht without a programme of work ahead of them. The Knysna 500SE is a respected design from the drawing office of Angelo Lavranos — a fractional sloop rig on a light, stiff hull form that gives genuine sailing performance without sacrificing the comfort that makes extended cruising enjoyable.

The ownership history speaks for itself: one careful owner from new, limited to three months of use each summer, with dry storage every winter. The evidence of this care is visible in the condition of the deck hardware, the quality of the canvas, and the freshness of the 2024 sail wardrobe. The new Profurl electric furler in 2025 rounds out a rig that is straightforward to manage short-handed.

Below, the Owner Version layout provides three en-suite cabins — a practical arrangement for a couple using the yacht as their own, with the flexibility to accommodate guests in genuine comfort. The twin Climma air conditioning units, the Kohler generator, and the comprehensive Garmin electronics suite mean that Impulse 1 is as well-equipped as any catamaran of her size in the Ionian. For the prospective buyer looking for a capable, thoroughly upgraded performance catamaran based in Preveza, she merits an early inspection.
