The ButterCup is a performance Groveller surfboard, designed to put a smile in your surfing even when the waves are small.

The ButterCup is designed to make surfing easier and more fun on days when the surf is  less powerful and not overhead. This is done by elegantly placing a large amount of volume into a small package helping you paddle and allowing the board to easily glide and float over whatever section you come across. Paired with modern rails and contours the board will carry you through cut backs, whips and surf sharply like a high-performance surfboard.

It has a unique deck profile, with a regular curved deck contour at the tail moving into a flat deck at the nose. The flat deck will improve your chest comfort when you paddle and helps increase the surfboard volume and paddle power.

The rails are 60/40 rounded with a deck bevel at the nose and centre with a hard edge developing towards the tail. The design stops rail bogging but also allows you to cut into the face, helping hold your line in sucked up critical sections.
