The makers of the semiSUBMARINE

Agena Marin grew out of a passion for boats and the explorer spirit of our founder Mladen Peharda, who made the first DIY prototype with his wife, in their back yard.
Fast forward a decade, and his passion turned into a successful company, private, fully-equipped shipyard employing 15 professionals, and with over 35 sold boat business solutions sold across the globe.
