A sporty alternative to the fully enclosed cruiser
The Sealine S335 is included in Barcelona International Boat Show’s 2026 on-water line-up, measuring 10.31 metres overall with a 3.50-metre beam. The model applies the German builder’s emphasis on bright interiors and flexible living arrangements to a sportier, more open deck configuration. Compared with the Sealine C335, the S335 is designed to bring the sun and fresh air into the cockpit more directly.
The boat's dimensions allow it to sit within Leisure Boat Guide’s recreational-boat coverage while offering sufficient space for an occasional overnight family visit. Its inclusion in the October programme is a chance for buyers to view an existing model, not a claim that the design has only just been launched.
Two roof openings and a generous bathing area
Sealine lists two opening roof sections and a substantial swim platform among the S335’s exterior features. Its cockpit is arranged for informal meals and relaxation, with the foredeck offering another place to sit when stationary. The combination can be attractive in a Mediterranean summer, where owners regularly alternate short passages with long afternoons at anchor.
The mechanism and weather sealing of opening roofs deserve attention because these parts will be used frequently in changing conditions. Visitors should check how the covers can be closed in rain, where drainage runs and whether instruments remain visible with the roof in different positions.
Layout choice under the deck
The S335’s interior is not limited to a single fixed cabin plan. The manufacturer describes multiple below-deck arrangements with up to two cabins, a head and different saloon or galley choices. One option converts the forward sleeping space to a social area with a U-shaped sofa and table, allowing owners to favour either sleeping capacity or daytime accommodation.
Each arrangement has consequences for storage and privacy. The practical test is to imagine a rainy evening with everyone aboard, considering ventilation, headroom, bathroom access and the ease of preparing a meal. A configuration that makes sense for a couple may not be ideal for a family with children.
Handling and the operating budget
Sealine advertises propulsion choices reaching approximately 540 horsepower and speeds up to 31 knots depending on installation. Those figures should be treated as model options rather than promises about any specific exhibit. Buyers will benefit from measured fuel use, access to engine-room service points and clarity on local repair support.
At the Barcelona show, the S335 can be compared directly with hardtop weekend cruisers and open dayboats. Its strength is the combination of fresh-air living and flexible below-deck space. The deciding questions should include equipment costs, practical sea-trial comfort and the yacht's suitability for the home cruising area. The opening cockpit also benefits from a realistic assessment of winter or shoulder-season use, when a protective enclosure and reliable heating could be more important than sun-lounging capacity. Owners should check the exact specification rather than assume every option is standard.
