RPM iWindsurf – Inflatable Windsurf Board for All Levels
From your first waterstart to full-planing gybes, the RPM iWindsurf is all about accessible, real-world freeride performance. Designed to deliver fun across the skill spectrum, this board combines generous volume, smooth control, and the travel-friendly advantages of inflatable construction—without compromising on performance.
Its compact shape planes early, carves beautifully, and feels remarkably responsive underfoot. Add the centre fin for upwind tracking as you learn, or ride free and loose as your confidence grows.

Two construction options:
- Single Layer (15 PSI) – Lightweight and great for casual performance

Easy to Store. Fun to Ride. Ready to Travel.
RPM iWindsurf – your all-round inflatable for freeride flow and effortless progression.
Our RPM boards are supplied with :
- High-quality double-action pump
- Ergonomic backpack
- Footstraps & fins
- Repair kit
The board do not come wiht Baseplate.
- Use a Cardan type baseplate for our Iwindsurf boards.
Board construction directly affects stiffness, weight, and durability. Stiffness is crucial as rigid boards generate significantly less drag than flexible ones.
Inflatable boards use "dropstitch" PVC—two layers of fiber-reinforced PVC connected by vertical threads of equal length, creating flat top and bottom surfaces. Board shape comes from sidewall design and slight top/bottom layer length differences.
Three main dropstitch technologies exist:
- Single layer (SL): Basic and affordable, ideal for light recreational use
- Double layer: Enhanced with extra PVC laminate—heavier but much stiffer and more durable
- Fusion Composite Dropstitch (FCD): Premium construction with more fibers and less PVC/glue, creating lighter, stiffer, and highly durable boards
Unifiber strives to offer a versatile and budget-friendly alternative to common hard-body beginner and freeride boards. The result – our iWindsurf range – combines fun, exciting, accessible windsurfing with a package that is compact and easy to carry around.
We maintain a extremely high standard of quality control. In addition to numerous checkpoints during manufacturing we do a final 72-hour test to check for any possible leakage. For every single board.
Fusion Composite Dropstitch technology is used in our boards to provide top-rated strength and stiffness, and minimal weight.
We build gear to last — and we back it up.
- Year 1 — Unconditional: Full coverage, no questions asked. Any issue, we make it right.
- Year 2 — Conditional: Continued coverage against manufacturing defects.

Single Layer vs. Fusion Composite Dropstitch Comparison
SL vs FCD
Single Layer (SL) offers basic construction with standard vertical dropstitch fibers (18PSI capacity), single PVC sealant, and simple rail reinforcement—making it lighter and more affordable but less rigid.
Fusion Composite Dropstitch (FCD) features advanced integrated construction with multiple fiber layers fused directly to the shell, high-density vertical fibers (25PSI capacity), and woven high-tensile strength materials—delivering superior stiffness, durability, and puncture resistance with a rock-solid core.
