HTDS (High-Tech Dropstitch) Material
HTDS lets us build inflatables with flat surfaces that can be inflated to rock hard rigidity. You get hard shell performance along with ease of travelling, carrying and storage.
HTDS enables you to inflate the board to 15-20 psi, creating a very stiff structure which behaves almost as well as a stiff board.
Furthermore HTDS provides the following advantages:
Storage – When deflated the board can be stored in a compact place (closet in your home, trunk of your car).
Travel – When packed in the storage backpack it can be checked on an airplane as normal luggage, taken on a train, bus or in the trunk of your car.
Hiking – You can reach a body of water that’s is not accessible by car: lake in the mountains, river in a canyon, sea shore away from the road (you cannot take a large stiff board there).
White water – Our boards and kayaks are better suited to handle bumping against rocks or floating logs than a stiff solid board.
Also if some areas are not passable (rapids, waterfalls), you can pack the inflatable and hike around the obstacle before entering the water again.
Yoga – Even when inflated the board is still softer than a stiff board and will be more comfortable to lay on and on your knees, elbows, feet and hands for yoga poses.
What makes it possible? Tens of thousands of fine threads stitched between two layers of the highest quality PVC.
The extremely resistant outer skin layers consist of two airtight PVC sheets laminated on both sides of a 1000D polyester material. This stiffening outer layer is then machine laminated to the 500D polyester dropstitch fabric. This innovative pre-lamination without manual gluing creates the HTDS composite. Furthermore our paddleboards have "TOP and BOTTOM STINGERS" or all over the top and bottom high pressure resistant reinforcements, this gives an extra high-pressure resistant reinforcement. It delivers a unique balance of weight, stiffness and durability. The result is high quality durability and finish. ROI iSUPs and iKayaks are High-Tech and beautiful.
Choose your ROI-iSUP...
When choosing your SUP you should take under account several parameters:
The Hull:
Planing hulls: Flat and wide, designed to ride on the water. It makes them maneuverable so they are good for leisure paddling, SUP yoga and white water. But they are somewhat slower and do not track as well for efficient paddling.
Displacement hulls: Narrow pointed nose like a boat or canoe that is designed to push the water aside efficiently. It makes them track straight, fast and efficiently so you can paddle more vigorously while going straight. They are good for fitness paddling, racing and long distance touring on relatively flat water. They will not be as good when maneuverability is critical like white water rafting.
The Length:
Medium board (10’ to 12’) make great all round and yoga boards.
Long boards (12.6’ and above) are best for speed (racing) or long distance touring.
The Width:
Wide boards: (30” and up) are significantly more stable than narrow boards (30” and lower). So wider boards will be preferred for beginners, yoga and loaded touring
Narrow boards: will be chosen for speed by more experienced paddlers who will not have stability issues with narrower boards and may prefer them for speed and efficiency of paddling.
The Thickness:
The thickness increase the volume of the board and its load carrying capacity, but it will also increase its stiffness. In general, we recommend 6” thick boards that will always behave much more like a stiff board and rather play on the length and width to adapt the volume.
Fins:
Fins increase stability and tracking. There are three main fin configurations: A single central fin, three similar sized small fins (called thruster) or a central main fin with two smaller fins on the sides.
Single fin: Good tracking and minimal drag. Good for flat water paddling, preferred for racing boards.
3 fins: (thruster) or 2+1 fins: Straight tracking on flat water and better directional control. Commonly used on all-rounders and touring boards for stability.
