Customer reviews

"I first tried it out myself at the trade fair in Werder in late summer. As a committed canoeist, I was initially a bit skeptical, but I was completely convinced. The SUP loses absolutely nothing in terms of its sportiness, but gains so much more comfort, allowing you to simply relax and spend time on the water."

Tobias Illmann

"Innovation and creativity are reflected in Supfix products. Impressive workmanship with attention to detail."

Dr. Canio Germano

"I was lucky enough to try out this great innovation at a trade fair. It was great fun and I highly recommend it to anyone who enjoys water sports!"

Hauke ​​Naujok

"Initially I was skeptical about ordering online without seeing the products beforehand, but the experience was flawless. The box is very elegant, the delivery was fast, and the quality of the products is excellent. I am happy to recommend Supfix!"

Daniel Rodriguez

"Why hasn't anyone done this before? Awesome product! I'm very surprised how long the motor lasts and it's brought my SUP out of retirement. I'm looking forward to next year when it can really be put to good use."
A CLEAR BUY RECOMMENDATION! 10/10"

Frequently Asked Questions

In this section, we answer the most important questions about our products, shipping processes, payment methods, and return policies. Our answers are clearly structured, easy to understand, and provide you with reliable guidance throughout your entire purchasing process.

  • - Yes, Supfix is ​​designed to be mounted on any standard SUP board (from 75-85).

    - If you have a board of a different size, straps in other lengths are available in our online shop; these can be quickly replaced with two screws.

  • Don't worry, you don't have to choose one of the options right now! The basic structure is a Supfix-One for a SUP board. If you want to connect two SUP boards (they don't have to be the same SUPs) to form a catamaran, either now or later, you'll need each of your two SUP boards with a Supfix-One. The two Supfix-Ones can then be easily connected in just a few steps and without tools using the included flexible fiberglass rods. It doesn't matter whether the boards are floating in the water or lying on land when connecting or separating them.

    You can connect any number of Supfix-One units together; one trimaran isn't the limit. Any number of Supfix-One units can be coupled on the right and left sides using the included fiberglass rods.

  • - No, our Supfix is intended as an add-on for an existing SUP board.

  • No! With Supfix, you're completely flexible. You can paddle standing up as normal, with the chair folded down at the back of the board. The chair is securely attached to the rear base, the system's main body, so it can't fall into the water. When you want to take a break or continue paddling comfortably seated, simply fold the chair forward and lock it securely to the front base using the fasteners – no tools required.

  • No, we designed the two base sections (main body) to fit easily into the carrying bag of your SUP board, one on each side. The fiberglass connecting rods are stored inside the base sections and securely locked in place until needed. You simply carry the chair under your arm, as it weighs only 3.3 kg.

  • The water doesn't need to be perfectly calm. The low center of gravity when sitting makes it easier to paddle even in small waves than if you were standing on the SUP board.

    - If you have one or more boards connected, small waves are no problem at all, as the fiberglass rods compensate for the wave movements.

  • No! Supfix can be mounted on your board without tools in just a few simple steps. With a little practice, you can do it in under 3 minutes!

  • Yes, it's currently in final production and will be available in the online shop shortly. The add-on will fit any previously purchased Supfix chair.

  • - Yes, it will soon be available in our online shop with two different motor variants for single or triple fin setups and two battery capacities.

  • - Yes, if your board can support the weight of the people, then it's not a problem.

    - On a catamaran, and especially on a trimaran, this is a popular way to, for example, put two children one after the other on one board.

  • - No! We designed our Supfix so that we can replace each component individually.
