AquaStar K-310 is a professional high-speed inflatable boat with increased safety.
It consists of four hermetic compartments (sealed cylinders). Three of these compartments make up the inflatable boat's frame. The fourth compartment is the keelson cylinder. Between the hermetic compartments of the frame, the bulkheads are of a bag-like design. If one of the boat's compartments is punctured, the bag-shaped bulkheads are activated in the direction of the puncture. This maintains the pressure in the damaged compartment, and the boat remains afloat. A motor with a maximum power rating of 15 hp can be installed. The boat is made of 5-layer reinforced PVC fabric with a material density of 1100 grams per square meter.
The boat has a minimum load capacity of 450 kg. Load capacity is always measured with one deflated cylinder, simulating a breach in the pressurized compartment.
The boat's design includes a fixed transom for the motor with a standard 38 cm foot. The wooden bottom (what the boat's feet stand on) is rigid and solid. It consists of four wooden segments (floors) fastened with aluminum fasteners and, when the boat is inflated, forming a single rigid deck.
The boat bottom is made of PVC fabric with a density of 950 g/m2.
The keelson is an inflatable structure. It looks like a tube expanding from stern to bow. It is located between the fabric bottom and the wooden deck. When the keelson is inflated, the space between the bottom and deck expands, creating significant tension on the fabric deck. Due to the deadrise, boats of this type are much more maneuverable than flat-bottomed boats. The keelson also improves load-carrying capacity, unsinkability, stability, and, most importantly, safety.
Along the bottom, the keelson is protected from mechanical damage by a thick protective beam. A special wide rib with a protruding rib is also installed around the perimeter to protect the sides from mechanical damage. The protruding rib cuts off spray while the boat is underway.
Along the boat's sides, aluminum reinforcements—stringers—are installed internally. These stringers serve several functions: they rigidly support the bottom and strengthen the boat's frame against buckling and bending in waves.
The two benches (also known as seats or stools) are movable. They are attached to special rails (guides) at the top, along the boat's buoyancy tubes. This feature of the boat offers several advantages (for example, if you place all the benches together, you can create a wonderful table). It's especially convenient for people of different heights.
Three handles are attached to the bow cones for easy transportation. The boat is equipped with spray gussets at the corners between the rudder tube and the transom at the rear. The gussets help to deflect splashing water that occurs when the boat is in reverse or when the throttle is released after planing.
A drain valve is mounted at the bottom of the transom, allowing water to be drained without capsizing the boat. The transom's end and sides are protected by pads. These pads prevent mechanical damage caused by motor operation.
All wooden elements are made from moisture-resistant marine-grade plywood. Hardwoods are used throughout, including oak, acacia, and birch.
