What you get - Situational checklists for real boating moments: departure, docking, anchoring, sailing, night navigation, fueling, and more - Recurring maintenance routines that help you stay ahead of service and seasonal tasks - Compliance-ready activity log: automatically track completed checklists and key actions for better reporting - Document storage for manuals, certificates, receipts, and boat paperwork — ready when you need it - Fast sharing: keep essential boat info in one place and send it when checking into a marina/harbour (or when asked by insurance/authorities) - Designed for all boaters: recreational day trips to serious passages, power or sail MarinMaster is free. A Pro version is coming with advanced features for professional workflows and deeper customization. Safety note: MarinMaster supports good seamanship — it does not replace training, local regulations, or the captain’s judgment.
