Excess 12

2022 Excess 12 | 2023 Pulse Line


Delivered in 2022 and built to 2023 Pulse Line standards, this Excess 12 catamaran blends lively performance with refined comfort. Designed for sailors who value responsive handling and sleek styling, she stands out with upgraded rigging, twin 45HP Yanmar engines, and a contemporary lightweight interior.


The vacuum-infused hull features a raised sheer line and sharp chines, combining stability with speed. The Pulse Line package enhances her sailing edge with a 0.9m taller rig, square-top mainsail, Code-0 with bowsprit, electric winches, and Dyneema steering cables for precise helm feedback.


Below deck, the layout offers four double cabins, two bright heads with showers, and a convertible saloon berth. The open galley is equipped with a gas oven, 90L fridge, and 12V freezer, complemented by generous natural light and modern finishes. Interior headroom reaches 2.10m, while the “Fast and Curious” personalization package brings distinctive style throughout.


Her specification includes Raymarine navigation, AIS, autopilot, inverter, davits, and upgraded lounging features, making her ready for both coastal cruising and longer passages. Maintained in excellent condition, she is available now through Williams & Smithells International Ltd.
