Board breakdown

01 December, 2021

Everything you need to know about our two hull technologies.

The launch of Radinn’s XDL construction—the latest in our growing line of hull technologies—means more ways to build the perfect jetboard for every surf setup. But how do you know which hull style is right for you?

We sat down with Radinn’s Chief Product Officer, Martin Malmqvist, to chat about the differences between our XDL and LTD constructions. Read on to learn about the breakdown of each board.

XDL Hull Tech

Our newly-developed XDL Hull Tech stands for Extremely Durable and Lightweight. Martin describes the construction, which consists of high-impact thermoforming around an airy polystyrene core, as feeling like a "pure plastic material."

"The very outer layer of the hull is a plastic sheet formed through heat and vacuum around the board," he explains. "It has the extreme ability to withstand scratches, scuff marks, and those kinds of blemishes."

In addition to cosmetic durability, Martin also notes that the XDL Hull has high impact durability thanks to additional fiberglass layers lined throughout.


"It’s quite difficult to punch a hole through this board if you hit something or drop it," he says. "There are layers of glass fiber in different places to achieve the optimum durability in those specific parts of the board. In certain parts of the board there are even strips of carbon fiber in addition to the glass fiber. So we are further creating strength just where it’s needed."

LTD Hull Tech

For those familiar with Radinn jetboards, LTD Hull Tech is what you already know and love. LTD Hulls are comprised of several layers of glass and carbon fiber, resin, paint, and varnish and provide the jetboards with a more elevated feel.

"Compared to our XDL Hulls, LTD Hulls should be considered higher-end," Martin says. "They’re actually handcrafted. The core of the board is precision molded in an industrial fashion, and then the various layers are added by hand according to years of board-building experience."

Martin adds that the final layer is fixed and formed into shape by a vacuum, before the paint and graphics are added on manually.

"The result is a board that feels more premium," he reiterates.
