IMPULSE is a rare, special edition Knysna 500SE that bridges the gap between luxury cruising and sailing performance. She has been exclusively owner-operated, used only three months each summer since 2020, and kept in dry storage every winter.

Key Highlights:

• Upgraded Sail Plan: Featuring a high-performance square-top mainsail (New 2024) and an electric screecher furler for effortless, short-handed power.
• New 2024/2025 Rigging: Equipped with NorthSails Norlam Xi11/09 sails and a new Profurl NDE2 electric genoa furler (2025).
• Robust Energy Systems: 760Ah Mastervolt bank supported by dual high-output alternators and a 7kW Kohler generator for off-grid autonomy.

• Full Bluewater Kit: Includes a 100L/h water maker, Iridium-GO, and a 3.6m Infanta semi-rigid tender with a 20hp Mercury.

Turnkey and SA VAT paid, IMPULSE represents a unique opportunity to acquire a modern, highly-upgraded bluewater catamaran in exceptional mechanical condition.
