Which Earth River SUP Board Should I Buy? (2024 Update)

Which Earth River SUP Board Should I Buy? (2024 Update)

An intense focus on quality and design has made Earth River SUP (ERS) stand up paddle boards the best and most versatile inflatables on the market.  Pumped Up SUP has worked very closely alongside ERS with both entities starting around the same period and evolving together as a part of the Maryland / Virginia / DC paddling communities. We’re very proud to represent ERS and see it grow from a dedicated project in 2012 to make a better and more rugged inflatable SUP for rental and paddling schools, into a leader in inflatable technology and manufacturer of world class paddling equipment.

ERS boards excel in stability, tracking, and agility and include performance enhancements such as configurable fin systems and ergonomic kick tails, allowing the rider to perform at the highest level in varied conditions.

ERS riders were running rapids and surfing inflatable river surfers when it was just a bad idea. Forming concepts when no one knew what was possible in the inflatable sphere, the design teams river experience and some with 40+ year surfing backgrounds helped lead to the ERS design philosophy of Lake - River - Coast. Each board series has specific advantages to ensure you are riding the best performing inflatable SUPs in its size and shape category.

The 10-7 S3 (10’7”x32’x5”) board outline is the default “go-to” shape in the ERS collection, as it strikes a perfect balance between length, width, and thickness, crosses over adeptly between flat water cruising, surfing, whitewater, yoga and fitness paddling and works for all but the lightest or heaviest riders.

The 10-7 S3 is a perfect board shape for all types of paddlers as it provides an extremely versatile SUP that excels in all water.

The 10-9 S3 (10'9”x34”x5”) DECK shape meets the needs of riders who want some extra stability to gain confidence while learning or to more easily handle choppy water conditions. It's fast across the water, easy to pack up and can be even used for surfing small waves and lower whitewater 

The DECK series features the lightest weight construction and a full deck pad to excel as a Yoga or Casual outing SUP board.  The center handle wrap is removable so you can lay completely flat on the board while not giving up the attributes that make it a great all round SUP for casual paddling. 

ERS 10-9 Deck

The 9-6 S3 (9’6”x31”x5”) shape provides a more compact and agile option that is very fun to ride in surf and lower whitewater and takes less energy to carry and inflate.

This board suits people of smaller stature as an all round board, but allows a great deal of flexibility for riders of all sizes who want to get a little more adventurous with their paddling pursuits. A lightweight versatile shape that can be used in any type of water available in DECK, SKYLAKE and DUAL configurations. 

ERS Deck

S3R - All-Around River SUP Shape 

The 9-6 S3R (9'6"x36"x6") shape is the perfect 36" width board for paddlers who want the confidence to run all grades of whitewater and have a board that is still actually fun to paddle on the flats. Upstream, down rapids, and play time on waves. 

Higher tuned rocker and LRC 4+1 fin set up give the ultimate in flexibility while the XL deck pad and front bumper gives scope for different uses. 


GT - Touring SUP Shape 

The 12-6 GT (12’6"x32”x6”) is a touring shape designed for covering distances with enhanced glide, but wide enough that you can paddle leisurely without much concern for your balance. It brings something different to the touring board class in that it has been designed as a fun multipurpose board that isn't confined to the typical touring class board design parameters. 

It's a touring board that allows a much wider range of paddling than most on the market, and is the choice for those who want a long board with all-around features. 

ERS GT Touring

X3 - Crossover SUP Shape 

The 10-0 ERS DUAL (10’x33”x6") is a crossover board designed for dynamic performance in whitewater and ocean surfing, while having increased volume for heavier riders and plenty of speed for flatwater paddling.

It's a short, fun board that provides a unique entry into the ERS lineup for paddler who wants a great river centric board that crosses over to other disciplines without bringing the bulk and flat water sluggishness associated with large whitewater specific boards. Perfect for the adventurous paddler looking for something different as a additional board in their quiver.

What Do Earth River SUP Boards Come With?

All ERS SUP boards come with a convertible backpack/rolling bag and dual action manual pump. DECK, SKYLAKE COLOR and ERS DUAL boards also come with an assortment of fins with mounting hardware. The rolling backpack is sturdy, has oversized wheels to facilitate travel through airports, and is generously sized to leave extra room for additional gear and clothing while traveling.

The included manual pump is a compact and lightweight dual-action design, which makes the inflation task as efficient as it can be with a non-electric pump.

Other accessories that you shouldn’t be without can be added at a discount at the time of board purchase, including an ERS 12VDC electric pump and a choice of personal flotation devices.
