ERS DUAL 10-9 S3 | NEPTUNE


The ERS Dual S3 10-9 NEPTUNE is the tough and ready workhorse of the ERS line up that excels in stability, balance, and use in all conditions. We gave it 34 inches of width, a sweet spot for balancing stability, speed, and fun. There are wider boards out there, but the facts are that 34 inches is the maximum width that maintains glide, correct body position (easy reach-over), and responsiveness.

THE MOST STABLE ALL-AROUND INFLATABLE SUP ON THE MARKET


The DUAL S3 NEPTUNE gets you out on the water on days when choppy conditions might deter you and gives you an incredibly stable platform for taking on rapids, serene flatwater or casual long distance paddling.  The NEPTUNE features an azure color and a deeper blue rail binding. The board is manufactured using our Dual Thermal Laminate and the ERS X9 construction method.

DESIGN AND SHAPE


LENGTH - 10'9" / WIDTH - 34" / THICKNESS - 5" / WEIGHT - 26LB / RIDER WEIGHT - Up to 225LB (245 for advanced riders)

PERFECT FOR: Riders who want stability in all conditions, learning and casual use SUP, big and tall paddlers, passengers and cargo, small wave surfing, fishing, yoga, acro, photography, choppy water, rapids up to Class II.

PERFORMANCE

The ERS Dual 10-9 S3 NEPTUNE design is an ideal fit for a medium build to larger / taller paddler, but thanks to its 5" thickness, it can be enjoyed by everyone who wants stability and performance.  Despite its larger dimensions, it's  fast across flatwater due to the tuned shape and carefully graded rocker. This can be further enhanced by running with a single long center fin such as the included 9" option. Shorter fins will allow you to explore shallow areas. Its volume makes it an incredibly fun family board for taking the kids or pets out with you on paddling adventures, while giving you the performance you need in more challenging water.

STABILITY! And convenience. Just got back from trip on the NC coast and had awesome time in ICW and ocean.

DUAL S3

The DUAL S3 NEPTUNE is NEW for 2021! Below are some insights from the V3 from previous years (previous length was the 11-0 in this series) but be sure to see our reviews and insights page for more info on the DUAL series

Like the ERS V3 10-7, I had the opportunity to use the ERS V3 11-0 throughout the spring and summer to lead various SUP classes, instructor workshops, and for my own paddling ventures.  I found the 11-0 to be a supremely stable platform to paddle in various conditions. While not quite as maneuverable as the 10-7, the 11-0 performed really well in the river environment, specifically making front ferries, eddy turns, and peel-outs.  The 11-0 became my go-to instructional board in calm or easy moving water due to its stability and relative speed.  With the 5” thick rails and the heel-pad, I found the board very easy to move around on and step back to submerge the tail for pivot turns.  Additionally, the size of the board allowed for easy storage for all the necessary equipment one may need on a full day on the water.  

Since I’ve got it in August I paddle pretty much every morning at sunrise at Riverbend Park and before that, a month on Cape Cod. The package you put together is just amazing and the contrast to my old 4” Waterman is amazing.  A completely different boat. I upgraded to the 11-0 earlier this year, use it almost daily, and I am still amazed and at how well it performs.  I do a lot of photography and video on the Potomac River and bring a tripod and three very expensive cameras onboard.  It may seem risky to carry so much sensitive and high-quality equipment on a board, but considering the stability and maneuverability and downright fun, I vastly prefer the 11-0 to kayaks or open boats.

Myself and several dads take our kids to a lake every summer. Think 30 dads and over 100 kids of all ages. A few years ago several friends started acquiring inflatable SUPs. I had tried a few brands and ended up liking the features and reviews of the ERS boards. I am 6' 5" and 200lbs so I needed a stable board that would track well. I was new at the sport but knew I wanted to make the investment and have one that lasted as I grew confident in my skills. I could not be more happy as are my kids. We love taking it out throughout the summer and taking it on long journeys. Now others are following my choice of ERS boards and we hope to be paddling with many more this summer. Thanks for a great product.

I wanted a board I could cruise on in lakes but also feel secure on in whitewater. This board is perfect! My pooch loves it too. I’ve taken it on Price Lake off the Blue Ridge Pkwy, including fir a full moon float, and several times on the New River in Todd NC. Most recently I floated sections of the Buffalo River in AK while on a several day float trip. I love that it is stable but still super responsive.

Ultragrip Deck Pad

Grip you can trust in the toughest conditions. We've worked at refining a rubber compound to produce a stronger, higher density and up to 40% thicker deck pad than other well known high end SUP brands. In addition to its traction advantages we have kept the compound light so as to avoid adding unnecessary weight to our boards.

The UltraGrip diamond structure works by channeling water to increase dry surface contact. It's incredibly comfortable to stand on even for hours on end and will perform every time, in any type of water.  Providing exceptional comfort and grip, partnered with a removable neoprene handle it creates a clutter free flat surface that is great for all SUP activities.

ENHANCED DYNAMIC RAIL (EDR™)

The next generation in advanced rail technology.  The Enhanced Dynamic Rail is built right into every Earth River SUP DUAL board. There are no unwieldy rail rods to fit and carry each session, no extra weight from excessive PVC layers or ineffective ‘carbon’ layered rail tape. The EDR is designed to enhance the ERS experience in active / moving water environments such as surf, rapids or rougher water to give you a better paddling experience. Riders apply force at a multiplier of their body weight when leveraging turns / making adjustments in rough water and the EDR provides resistance when you need it – without affecting the glide of the board on flat water or carrying weight when you are off it.

ERS X9 CONSTRUCTION

ERS is known for the best performance and reliability and in the industry, which starts with superior board construction. The X9 method using Thermal Fused Laminate creates a permanently sealed board outline that is fused during fabrication to create a rigid structure without requiring high inflation pressure or excessive volume.

ERS SUP boards are hand built one board at a time by skilled technicians under ISO9001 manufacturing certification to ensure consistent and repeatable processes and attention to detail in each individual board. The result is a board with better glide, unmatched rigidity, and proven longevity.
