IMPORTANT NOTICE
ModulSea displays official S-57 and S-63 charts using its own Metal-based rendering engine, with Apple MapKit as the worldwide base map. Imported nautical charts provide detailed marine cartography but must not be used as a sole primary navigation aid. Always rely on certified instruments for safe navigation at sea.
 
Built by passionate sailors. Whether you own a sailboat, work as a skipper, or manage a fleet — ModulSea is your all-in-one navigation companion.
