Head Office Located in Australia




NAUTYCAL is a privately owned technology company founded at the Queensland’s Sunshine Coast in Australia. What does the name mean you may wonder? It’s simple, NAUTYCAL is ‘nautical’ spelled with a ‘Y’ so we can use the name uniquely for our enterprise and have a registered trademark.


Because we can!  Because we care!  Because we connect!


The origin of NAUYTCAL started with the launch of Find a Crew™ in 2004. With the global success of findacrew.net,
NAUTYCAL was incorporated in 2009 to become the flagship for all our online maritime applications.


NAUTYCAL is a global online enterprise based in the small sea town of Mooloolaba at Australia’s Queensland Sunshine Coast. Its worldwide network is hosted from web servers in Australia, Germany, United Kingdom, and two servers in the United States.


NAUTYCAL has two directors; Find a Crew’s founder, and Find a Crew’s chief software engineer. NAUTYCAL has no investors, no debts, and operates with a  strong commercial business model, which is not selling any advertising, member information or statistics to third parties.

Many competing online crew websites have tried to copy what findacrew.net does, but the many privacy settings, security features, and the powerfull matching and search capapilites is what made Find a Crew the largest online marine crew and boat website in the World.
