Our story

Our journey — the Sea Paddleboard story

While studying at Brno University of Technology, I used to kayak on the Svratka river, and that passion stuck with me. After graduating I had nowhere to store a kayak, so I picked up a paddleboard instead — but it never gave me the comfort I was used to.

One summer by the sea, it hit me: why couldn't I sit right in the water while paddling, comfortably leaning against the board itself? That idea became the first prototype, then a Hithit crowdfunding campaign, and round after round of refinement.

Today, that idea has become Sea Paddleboard — the freedom of a paddleboard combined with the comfort of a kayak.

Key features

A versatile craft for the whole family

High stability and safety

A wider base and a low center of gravity deliver outstanding stability even in choppy conditions. Enjoy the water stress-free, without worrying about tipping over.

Comfortable seating right on the water

Thanks to a seat clipped in from underneath, you sit right at water level — a refreshing feeling on hot days and a relaxing way to spend time on the water.

Multi-functional use

Stand and paddle like a paddleboard, sit in the attached seat, or kneel. The choice is yours, depending on your mood and the conditions.

Lightweight and easy to carry

The inflatable construction is compact, folds down easily, and fits into a backpack — ideal for travel and day trips alike.

Built for the whole family

Designed with the safety and comfort of the entire family in mind. Kids can safely enjoy a ride with an adult, or on their own in shallow water.

Who is Sea Paddleboard ideal for?

  • For anyone who feels unsteady on a regular paddleboard and wants more confidence on the water.
  • For parents with kids who want a safer, more comfortable alternative to a paddleboard.
  • For anyone looking to relax and enjoy the water without wearing themselves out.
