The Sealine S335 is the German yard’s newest compact sport cruiser, a 33-footer that premiered in the refreshed S-series and brings Sealine’s reputation for clever use of space into its most attainable size. Built around a deep-vee hull and inboard power of up to 540 horsepower, she tops out at around 31 knots, pairing genuine sporting performance with the day-boat practicality the brand is known for. Topside she offers a large bathing platform, two generous sun lounges and a bow sun pad, with two opening roof sections to bring air and light into the cockpit. Below, up to two cabins and a choice of lobby and bow-cabin layouts let an owner tailor her for couples or weekend cruising, and the owner’s cabin can be converted into a living area with a U-shaped sofa. Sealine markets best-in-class headroom, window area and berth sizes for the class, making the S335 a rounded, versatile sport cruiser for owners who want pace and comfort in an easily handled package.

The S335 is built on a deep-vee hull matched to inboard power of up to 540 horsepower, giving a top speed of around 31 knots. That combination delivers the sporting drive the S-series name promises while keeping the boat composed and predictable in a seaway, the deep forefoot slicing chop rather than slamming through it. Inboard installation keeps weight low and central for balance and frees the transom for the broad bathing platform. For an owner the result is a genuinely fast day boat that remains easy and confidence-inspiring to handle, whether opening her up on passage or manoeuvring at low speed around the marina. German engineering and build precision are evident in how tightly the whole package is resolved.
Above deck the S335 is designed around sun and socialising. A large bathing platform makes swimming and water access easy and extends the usable space aft, while two generous sun lounges and a dedicated bow sun pad give guests room to spread out. Two opening roof sections flood the cockpit with light and air, so the boat feels open and connected to the water even at rest. The layout flows naturally from helm to cockpit to bathing platform, encouraging movement and conversation. It is a deck plan tuned for the Mediterranean day-boat life, where time at anchor in a quiet bay matters as much as the run to get there.
Below, the S335 offers up to two cabins with a choice of lobby arrangements and a new bow-cabin design, letting an owner match the interior to how they use the boat. Sealine markets best-in-class headroom, window area and berth sizes for the size, and the interior can be personalised with a range of colours and textures. The standout flexibility is the convertible owner’s cabin, which can be reconfigured into a living area with a U-shaped sofa, turning overnight accommodation into open daytime lounging. For a 33-footer the accommodation reads as unusually adaptable, suiting a couple after a sporty weekender or a small family wanting proper berths for occasional nights aboard.
Flexibility is the thread running through the S335. Beyond the convertible owner’s cabin, buyers select from multiple lobby layouts and the new bow-cabin design, so a single hull covers a wide range of uses. Interior finishes are customisable in colour and texture, letting owners put a personal stamp on the boat. The styling is unmistakably S-series, sporty and modern without chasing fashion, and the attention to window area keeps the interior bright and connected to the view. This modular approach is central to the S335’s appeal: rather than forcing a buyer into one configuration, Sealine lets the boat be specified as a performance day boat, a couples’ cruiser or a compact weekender.
The S335 premiered in the refreshed Sealine Sport range and is a current-production model, built in Germany with the brand’s hallmark engineering and finish. Power options run to 540 horsepower inboard for a 31-knot top speed, and the boat measures 10.31 metres overall on a 3.5-metre beam with a 0.98-metre draft, displacing around 6.1 tonnes. Indicative new pricing sits in the region of 310,000 to 460,000 euros depending on engine choice, specification and local VAT treatment, placing her competitively in the compact sport-cruiser class. As a factory-current model she comes with Sealine’s dealer and warranty support. For a buyer who wants a fast, flexible and well-built sub-35-foot day cruiser from an established German yard, the S335 is a strong and versatile choice.
