Pulse Raft

The Dropstitch-floor raft: rigidity and performance

On a raft, the floor matters as much as the tubes. The Pulse range is built around a high-pressure Dropstitch floor: instead of a soft deck, you get a flat, firm slab that transforms how the boat behaves. The Dropstitch principle is simple and proven — thousands of threads connect the top and bottom skins of the floor, so once inflated under pressure it keeps a constant thickness and turns very rigid. Born from stand up paddle and high-pressure kayaks, this technology gives the raft a hull stiffness close to a hard boat while keeping every inflatable advantage: light weight, small rolled size, quick rigging on the bank.

What a high-pressure floor delivers

A firm floor is not just about comfort: it changes how the raft glides, holds its line and reacts underfoot.

• Hull rigidity: the tensioned floor ties the tubes together and removes central flex. The raft carries load better and transmits paddle power.
• Glide and speed: the flat, smooth underside grips the water less, so the raft accelerates quickly and drains better on the flats between rapids.
• Tracking and responsiveness: the rigid hull answers more sharply to edging and line changes, a real plus for sporty descents and manoeuvring.
• A flat, firm platform underfoot: the crew braces, gets purchase and paddles with power without sinking into a soft floor; you can stand and move on board with stability.
• Drainage: combined with the raft's outlets, the high-pressure floor keeps the boat riding high and helps shed shipped water.

Dropstitch floor or soft self-bailing floor: which to choose

The soft self-bailing floor remains a safe bet: perforated, it drains water on its own in big rapids and is very forgiving, which makes it a reassuring standard for public rental and heavy whitewater. The Dropstitch floor favours performance: stiffer, it tracks better, glides more and offers a stable platform to stand and paddle hard. In return it needs high-pressure inflation and careful drying. In short: for passive safety and maximum simplicity in very pushy water, the soft floor does the job; for efficiency, glide and precise handling, Dropstitch takes the lead.

The Pulse models

The Pulse range has two thermowelded PVC rafts, both fitted with the high-pressure Dropstitch floor:

• The Pulse 415: Dropstitch-floor raft for 9 people, a compact, lively size at home on technical rivers and with mid-sized crews.
• The Pulse 470: Dropstitch-floor raft for 11 people, more volume and buoyancy for large groups and sustained flows.

To compare with our other constructions, see the versatile Avanti rafts (PVC, standard floor) and the Raptor rafts (long-life hypalon), or head back to our full rafting range to place the Dropstitch floor among every use.

What it is for

The Dropstitch floor targets sporty, committing descents first, where hull rigidity is felt at every stroke: quick acceleration, precise lines, a firm platform to paddle with power. It is also a favourite of guides and professionals who want a responsive raft and a stable platform to lead trips, and of crews seeking comfort — a floor that does not give way tires the legs less over a long day. Whitewater centres, clubs and performance-minded rental fleets get a boat that stands out on the water while staying transportable and fast to deploy.

Inflation and pressure

A Dropstitch floor is inflated much harder than the tubes: this high pressure is what creates the rigidity. Always respect the value shown on the boat's rating plate and manual, and check the pressure before every outing. Plan for a suitable high-volume pump: the tubes fill quickly by volume, then the floor is brought up to pressure at the end. Watch out for heat — full sun, roof racks, hot sand raise the pressure and can weaken the assembly; let a little air out if the boat stays exposed.
