In the Netherlands, Kees Radius has developed a round rig - in keeping with his name - that holds the infamous patent (see surf 6/1978). A circular cloth is attached to a semi-circular aluminium mast, the leech is tensioned by several battens. The highlight of the whole thing is the spar-like handle, which is designed to stand out from the patent-protected boom. Ten Cate had secured the rights to the Radius rig and spent a year developing it further together with the inventor, including the creation of a teardrop-shaped offshoot. But now Ten Cate has jumped ship and Radius is looking for new partner companies that want to circumvent the patent. He admits that his development is more expensive due to numerous small parts and that the board is more difficult to control due to the low pressure point. The most important message of the whole story: "In any case, his rig shows that development in surfing is far from over!"
At the "Spoga" trade fair in Cologne, all manufacturers are in a frenzy following the confirmation of the patent. While many boards are becoming more expensive in anticipation of long lawsuits and uncertain future prospects, manufacturer Akutec, for example, is proudly displaying the last page of the contract with Hoyle Schweitzer on its stand to convince customers of its legality. Schweitzer's lawyers, meanwhile, are curiously looking around the trade fair to find new ideas for circumventing the patent. According to insiders, they "were particularly surprised by the replacement designs for the boom" in Cologne. Mistral and Solar-Star, both of which had developed unconventional handle solutions, were seen by the lawyers to be on the safe side. However, these solutions never caught on.
