Our Heritage

Our company was founded in 1984 by Simon Johnson, who has synergistically combined his experience as a former competitive oarsman and professional rowing coach with his engineering expertise to design and manufacture the most innovative, ultimate coaching, umpiring and rescue catamaran on the market.



Solar power: Research and development is ongoing on a solar battery-charging system for the Rowing Solutions RS eCAT16.


Global: Our RS CAT16 Catamarans are sold in 23 countries around the world.


Eco-friendly: Our first electric RS eCAT16 is sold to the Slovenian National Rowing Federation.


Prestige: Henley Royal Regatta uses our RS CAT16 TV Catamaran to film 660 races for worldwide TV coverage.


Sustainable: We launch the new RS CAT16 with unique dreadnought reverse-bows & new formula roto-moulded tri-laminate polyethylene.


Cutting-edge: We are rebranded Rowing Solutions Ltd, specialising in the design, development and manufacture of catamarans.


State-of-the-art: SJI reconceives its catamarans of roto-moulded trilaminate polypropylene. Quality, durability, reliability, strong & lightweight.


Specialist: SJI focuses on building catamarans only, no longer boat parts, whilst also coaching professionally.


New beginnings: The first catamaran is built in our workshop near Henley-on-Thames. The hulls are built of Kevlar® sheet material. 


Firm foundations: Rowing coach/engineer/former competitive oarsman sets up Simon Johnson International, designing & manufacturing rowing boat parts & accessories.
