OWNER’S COMMENT:

Santosa was commissioned in 2017 to a high specification with both CAT 0 and CE Ocean A compliance in mind. Throughout her creation there was a clear focus on engineering quality, attention to detail and producing a yacht capable of serious passage making rather than simply occasional cruising. The emphasis throughout was on building the yacht, with engineering decisions driven by quality, functionality and long-term reliability rather than budget constraints.

Particular care was taken in marinizing systems and components, together with a bespoke high-latitude rig designed to make life easier offshore. The rig has proven efficient on ocean passages, allowing us to balance the helm effectively for comfortable hand steering and reducing the load on the autopilot when conditions allow. There is a real feel and connection at the helm, something we have always appreciated on long passages.

From our experience, SANTOSA has always felt safe and comfortable in heavy weather. Her skeg-hung rudder arrangement and substantial construction provide reassurance offshore, while the protected keel and reinforced forward sections reflect a philosophy of building strength and resilience into the yacht.

SANTOSA was successfully used for charter operations during 2018–2019 before Covid and has since been enjoyed privately, cruising extensively through the Caribbean and later in Norway and Svalbard. One of the qualities we particularly appreciated while cruising Norway was the combination of her 23m air draft and moderate 2.3m draft, which opened opportunities to navigate inland waterways and the archipelagos while still retaining the capability and confidence of a serious offshore yacht. This versatility allowed us to access areas that can often be less practical for yachts of a similar size.

Throughout ownership we have replaced and upgraded systems and components. Her ground tackle has always given us confidence at anchor and allowed us to enjoy remote locations with peace of mind.

Inside, the raised saloon has always been one of our favourite places onboard, providing panoramic views and an abundance of natural light that keeps you connected to your surroundings even in more challenging climates.

If circumstances were different and a sale were not being considered, our next ambition would likely have been preparing SANTOSA for the Northwest Passage.

SANTOSA takes her name from the Sanskrit word meaning contentment and acceptance — finding peace and satisfaction in what you have, even while facing challenges. We felt the name suited her from the beginning, because life aboard has always given us exactly that feeling: confidence, comfort and contentment wherever she has taken us.
