Saxdor 200 wins the BoB 2020 award

Summary of the award committee: “The Saxdor 200 Sport combines two features: convenience and ease of use, with the safety and comfort of a compact motorboat. It is easy and reliable to control, and maneuvering in the marina is extremely simple – an excellent choice for your first own motor yacht.”

Saxdor 200, the introductory boat of a new range combines the performance and fun of a jet ski with the comfort of a compact boat. The 200 also proves that affordable boating doesn’t mean compromising quality, seakeeping, versatility, performance or sexy styling. The hull geometry confirmed that a stepped hull can be safe on a small boat, without compromising performance or ease of handling. Saxdor 200 was introduced at the outbreak of Spring 2020 Covid-19 situation and hundred were sold worldwide within first month.

She represents a strong and new statement conceived by the Finnish boating legend Sakari Mattila. J&J Design was responsible for the naval architecture, design and engineering.

We congratulate the Saxdor team for this extraordinary achievement which opens the doors for success of the new range with the planned 320 and 400 models coming in near future.

The outboard-powered vessel platform S.A.F.E. was designed by J&J in
January 2017 and the legal protection process started in February 2017.
The US patents were granted in 2018 (US patents no. 10,370,067 and
10,150,537B2) and Eu patent (incl. Turkey) were awarded in August 2020
(EP5583023, in Germany DE60 20177021 705.0). Considered by the industry
as one of the major innovations improving the safety and convenience of
boats with outboard engines, S.A.F.E. was already applied on new J&J boat
designs like the Greenline NEO or Fairline F33 and several others. We
are looking forward to developing the S.A.F.E. as an unavoidable
solution for outboard-driven boats.



Saxdor 200 was presented by Hugo Andreas in the Motorboat & Yachting Magazine and Saxdor was described as the most exciting new brand of the last years. Citing the verdict : ‘It’s fast, stylish, fun to drive and much more practical than any jet-ski. It’s also unbelievably good value for money while managing to look, feel and behave like a much more expensive craft. I can’t think of another boat that gets anywhere close to offering that much fun for that kind of money.’
