Smaller boats enter the roof-system spotlight
Webasto is preparing a marine equipment presentation at Metstrade 2026 in Amsterdam, with the market introduction of two compact roof systems named SoLite 12 and SoLite 20. The German supplier's announcement, dated 21 October, places open and enclosed smaller craft at the centre of a launch that also includes cabin cooling and heating products.
Roof equipment can have a disproportionate effect on the usability of a modest-sized boat. Ventilation, shade and the ability to close up in poor weather are closely tied to whether a cockpit remains pleasant throughout the day. Webasto's announcement addresses those practical considerations rather than introducing a complete new boat.
SoLite 12 replaces an established design
The SoLite 12 is positioned as a successor to Webasto's BlueSky Glass roof. According to the manufacturer, it combines a refreshed appearance with improved ultraviolet filtering. The idea is to retain natural light and an open connection with the water while giving designers a compact roof module intended for integration into a smaller vessel.
An improved UV filter is relevant to the comfort of those seated below the glazing, although it should not be confused with a guarantee that an enclosed cabin will stay cool in all climates. Installation geometry, ventilation, nearby reflective surfaces and how the boat is used still influence the overall experience.
SoLite 20 targets T-tops and cabin craft
The SoLite 20 broadens the concept to applications including T-top-equipped boats and small cabin craft. Webasto describes the two systems as compact counterparts to its larger roof range, aimed at giving boat manufacturers more choice when allocating limited overhead space. This is particularly relevant where structural supports and electrical equipment compete for room.
Boat owners evaluating a factory option or a later installation should confirm compatibility with the exact deckhouse or hardtop structure. The announcement describes a new range, but it does not establish that every existing roof can accept the module without engineering changes. Weather sealing and drainage also remain critical to any marine roof installation.
Glazing, light and optional solar generation
Webasto says dark specialist glass is designed to reduce heat buildup under sunlight. Its package can incorporate blinds, ambient LED lighting and optional integrated solar cells. The proposed combination seeks to make a roof useful across several functions: bringing daylight inside, controlling glare and potentially contributing electrical generation.
The solar option deserves careful sizing rather than assuming it can replace the boat's ordinary charging system. Available roof area, angle to the sun, shadow from antennas and demand from refrigeration or electronics all affect the real contribution. Owners should ask for electrical output specifications for their selected installation.
BlueCool SX gains gentler compressor starts
A revised BlueCool SX line is another part of Webasto's marine announcement. These self-contained systems offer cooling capacities ranging from 6,000 to 27,000 BTU per hour and reverse-cycle heating. The company highlights Intelligent Compressor Control, which it says can reduce the starting current peak by up to 95 per cent.
That improvement could be helpful where a boat relies on restricted shore supply or limited generator capacity, because compressors can demand considerably more current at startup than during steady running. The figure is a manufacturer claim for the control technology; an owner still needs an installer to calculate total power use, circuit protection and battery or generator suitability.
A rooftop air conditioner for compact cabins
Webasto's Cool Top Marine adapts a rooftop cooling approach for small vessels, houseboats and commercial wheelhouses. Its stated cooling capacity is 5 kilowatts, approximately 17,000 BTU per hour. By placing the unit above the occupied compartment, the design can preserve interior lockers or machinery spaces that a conventional installation might consume.
The manufacturer also notes that the air-cooled system does not require a seawater cooling circuit. That could simplify some retrofits, particularly on boats where installing a through-hull intake would be inconvenient. Owners should still check roof loading, noise, condensate handling and whether the available electrical supply matches the product.
Air Top Pro 25 adds controlled cabin heat
For cooler conditions, the new Air Top Pro 25 air heater offers a stated output range from 0.7 to 2.5 kilowatts. Webasto describes quick initial warm-up followed by quieter, lower-output operation for temperature maintenance. Control options include integration with its ThermoConnect app, according to the company's release.
A compact heater can make a meaningful difference to spring and autumn boating, but the installation is safety-critical. Combustion-air supply, exhaust routing, fuel connections and carbon-monoxide precautions should be handled to the manufacturer's standards. An app interface adds convenience but does not replace correct installation and routine inspection.
Why the Metstrade introduction matters
Webasto says it is marking 20 years of marine-industry activity at the 2026 exhibition. The product group illustrates a continuing move to bring equipment once associated with larger cruisers into more compact recreational craft. Roof shading, digital control and better-managed starting loads can all matter in boats with constrained space and power.
The useful next step for boatbuilders and customers will be detailed product drawings, installation guidance and local availability from authorised suppliers. Webasto's announcement establishes the direction and headline capabilities; it does not disclose a universal fitted price. Comparing these options against the boat's dimensions and operating profile remains essential.
