8" ALL ROUND CENTER FIN*

The 8" all round fin provides a great balance between tracking, turning, and speed. This fin should be your go to for most forms of paddling.

9" DISTANCE CENTER FIN

The 9" distance fin is great on when you just want to glide longer distances. It excels at keeping the SUP straight, and enhancing stroke efficiency.

4.5" SPEED CENTER FIN*

The 4.5" fin provides great speed across the water and fast turning. Great for fast or slow water of any depth.

3" SHALLOW CENTER FIN

The 3" centre fin is prefect for shallow water when there is possibility of contact. Combine this with the 2" clicks you can paddle almost anywhere.

4.5" STANDARD SIDE FINS*

Great for hold and stability. A SUP staple that gives you excellent grip and tracking assistance in any type of water.

2" SHALLOW RIVER SIDE FINS

In extreme shallows, rocks, or unknown switch up to the 2" 'low profile setup or for a looser grip on a longer single fin setup.

FIN SCREWS*

Included is two centre fin thumb screws with plates - eight grub screws - and a customized fin screw key.

ERS PADDED FIN BAG*

We custom designed the bag to be an easy way to carry your fins, fin key, screws and anything else you need to set off on your adventures.

US Standard Center Fin Box

Our standard US Fin box has enough space to slide your centre fin up and down, to control how tight or loose your ride responds when turning. It will take any standard US centre fin and we include four distinct sizes in our DUAL range, and two centre fin screws in the in the pack to give you an instantly configurable package straight out of the box.

1. INSERT SCREW + PLATE

Place the screw + plate end of the fin into the box rail and push a forward or backward depending on the fin.

2. UNSCREW AND LEAVE PLATE

Undo the thumbscrew screw - leaving the plate in the box and put the screw in the fin again.

3. SLIDE TAB END

Slide the tabbed end of the fin in the box and slide up towards the opposite end to the plate

4. POSITION SCREW AND FIN OVER PLATE

Alight the fin screw over the screw plate and latch. Slide the fin back and forth from the tab end to help with lining it up.

5. LATCH AND TIGHTEN

Tighten until it has a nice firm hold but the fin can still be moved a little.

6. SLIDE UP AND DOWN BOX

Customize the feel of your ride by sliding the entire fin forward or backwards - and tighten the screw.

FCS Side Click Fin Box

Our side click fins are designed for ultimate performance. Unlike many cheaper or poorly designed systems, our click fins are completely removable. Our boxes will take included flex 4.5" clicks or 2” side bites, as well as allowing you to remove them completely and just use your centre fin. Our fin boxes are standard FCS compatible allowing near unlimited customization of your ERS board and like our standard US center fin box does not lock you into a proprietary system. Click fins simply click into place and we recommend using the included grub screws (one on each side in alternate corners) the help keep the fin in secure.

Performance and Flexibility

The Lake River Coast™ fin pack is specifically designed to compliment our performance inflatable board designs. Their flexible nature adds a little padding to the boards lateral movement, but remain stiff in the water for strong tracking and maneuvering. Much of the assumed knowledge of fin systems comes from surf board development, however all that knowledge doesn’t directly transfer to an inflatable SUP.

Inflatable SUPs can and will be used in different water such as rapids, rocky areas, or extremely shallow places. It is for this reason that a fin developed with optimal flex is preferred, and our fin system allows the use of most standard US centre fins and FCS compatible click fins should you prefer a harder fin in some water.

The board will turn quicker and feel looser, with the fin moved up front. With the fin pushed back towards the tail, the board will generally track straighter and have a stiffer turning feel to it. We recommend if in shallow water or if there is any chance of contact with your fin, that your should place the fin a little forward in the fin box so that upon contact, the fin has room to slide back preventing fin box damage. The universal US standard box allows further customization and a phenomenal range of fins - you are not locked into a proprietary system.
