Core Material

DECK boards start with an internal core of advanced fusion drop stitch, in which the outer PVC coating is directly applied to the base fabric layers. The overall layup consists of two layers of fabric which are oriented at an angular offset to minimize elasticity and permanently bonded in a glue-free process before coating with PVC.

Shape & Thickness

ERS DECK S3 boards are shaped to cover to cover all-around shapes that perform for paddlers of all sizes and uses. The use of advanced design and materials allows us to make a high performing board in 5” thickness, which lowers your center of gravity for increased stability and “grounded” feel, makes it easier to get back on the board from the water, and is easier to carry and faster to inflate.

Deck Pad & Handle

DECK boards feature a reptile grip surface. The main deck area is 40% thicker than the industry average and utilizes the highest density EVA foam on the market. The result is a deck pad that feels great on the feet, provides superior cushioning, and lasts longer than typical deck pads. The tail section has a raised foot bar which provides tactile feedback of foot positions and a raised back to keep the foot from sliding back when doing maneuvers that involve applying pressure to the tail of the board. The handle is designed to conveniently lay flat when not in use and has a removable neoprene grip wrap for carrying comfort. Removing the grip provides a flat surface in the center of the board for lying down for yoga or stretching, and keeps the surface free of obstacles for surfing.


Fin System

DECK S3 boards feature three removable click fins of equal size arranged in a classic “thruster” configuration. This setup distributes the fin surface area equally among the three fins, which keeps the total fin height of the board  lower than boards with a large center fin and allowing good control of the board.  This setup allows easy setup and pack down while still being ready for any challenges that require a skill step up from casual paddling.



ERS SKYLAKE boards include a host of hardware component upgrades, including stainless steel D-ring for leash and cargo bungee attachment and a genuine Halkey-Roberts inflation valve for reliable inflation and air seal.  Earth River SUP has a simple approach to component selection - We always use the best available component for every purpose, regardless of its impact on manufacturing cost.

ERS Compact Pump

ERS SKYLAKE boards come with an ERS Compact dual-action manual pump, which is designed and tested to provide the most efficient inflation performance in the most compact form factor. The internal valve configuration allows the single cylinder to deliver air on both the downstroke and upstroke, resulting in almost doubling the speed of inflation. The dual action is selectable and can be disabled when the board reaches pressures that make it easier to finish inflation in single-action mode.  The extra weight and bulk of a two-barrel solution does not significantly speed inflation when compared with the more elegant and compact single barrel dual action pump provided with ERS boards.

DECK boards come with the ERS Rolling Backpack, which is made of ultra-durable 1600 denier canvas and is sized to fit the board, pump, paddle, and accessories while leaving room for personal belongings. The bag is equipped with a convertible backpack strap system, strap covering for airline travel, two internal straps, 4 external cinch straps, three inside mesh pockets, generously padded handles, a paddle pocket, and smooth-rolling wheels.
