Owner Experience Review

Owners who have run a Custom Tri-DeckfromTIMMERMAN YACHTStend to judge it by hard miles, not dockside shine. The best-documented example, Latitude, was used by owner Anil Thadani for repeated Arctic expeditions, including a Svalbard circumnavigation and a full Northwest Passage. The same platform doubled as a base for family cruising, wildlife photography and education, and it has also been set up successfully for guest entertaining and charter on extended voyages.

On the water, the Vripack-designed full-displacement steel hull favors range and seakeeping over headline speed. Published figures cite a cruising band around 12–13.5 knots, a top near 14 knots, and a quoted range of roughly 3,800–4,000 nautical miles. Examples fitted with kort nozzles around the propellers have shown notably steady tracking and added protection in debris-prone, remote waters; as one captain noted after the Svalbard loop, they were among only a handful of boats to have done it.

Life aboard reflects purpose-built expedition thinking: the sky lounge is often described as the yacht's true living room at sea, complemented by a large sun deck, a beach club and a full-beam owner's suite, with layouts on larger examples offering five cabins for about 10–12 guests. Outfitting that supports long trips—such as a dedicated aquatic sports center with Nitrox, a large swim platform and beach club—has been used heavily on owner voyages. Ownership, however, demands rigor: Latitude completed an owner-mandated 11-month refit of about €3.2M as part of a 15-Year Class Survey, renewing engines/generators, shafts, sea valves, piping, HVAC and electrical; the Caterpillar C3412 mains had high recorded hours and were opened, inspected and overhauled, and the engine room has been arranged for straightforward service.

Pros and Cons

• Proven high-latitude track record on an example yacht, including Svalbard circumnavigation and a Northwest Passage.
• Long-range, full-displacement Vripack steel hull with quoted 3,800–4,000 nm range and steady course-keeping.
• Guest-friendly living spaces with a sky lounge 'living room at sea', large sun deck, beach club and multi-cabin layout.
• Significant lifecycle and refit costs documented, including an 11-month ~€3.2M survey-driven rebuild scope.
• Expeditioned examples can carry high engine hours; Caterpillar C3412 mains required major inspection and overhaul.
• Modest speeds for the size class (about 12–13.5 kn cruise, ~14 kn max) as a trade-off for range and robustness.
