Key Features

• Massive Capacity for 2–4 Passengers – At 157.4 inches (400 cm) in total length with a max load of 800 kg, the SD400 comfortably accommodates the whole crew for fishing trips, water sports, and outdoor expeditions.
• 3+1 Independent Air Chamber Safety System – Four separate air chambers mean that even if one is damaged, the boat maintains buoyancy and keeps everyone safe – a critical safety feature for offshore use.
• 30HP Motor Compatible – Reinforced transom supports outboard motors up to 30HP for powerful, reliable propulsion. Includes 2 aluminum bench seats for a stable, comfortable ride.
• Drop-Stitch Air Floor with EVA Decking – The rigid drop-stitch inflatable floor combined with EVA material on the deck plates delivers a firm, comfortable standing and seating surface – closer to a rigid hull feel.
• Portable Yet Sturdy – Gross weight of 59 kg with a compact packed size of 49.2 × 26.7 × 17.7 inches makes transport and storage straightforward despite its large on-water footprint.
• Complete Accessories Included – Comes ready to launch with 2 oars, repair kit, inflation pump, carry bag, and floor storage bag – everything you need right out of the box.

The SD400 is the go-to choice for serious boaters who want inflatable convenience without compromising on performance or safety.
