Route & legs

Cast off prepared.

Everything before you cast off
One plan. The whole crew. Nothing forgotten.
Crew coordination
Invite your crew into the voyage. Dates, route and duties live in one place — not scattered across a group chat.
Checklists that gate readiness
Documents, safety, boat handover — checklists unlock step by step, so “ready” actually means ready.
Shared packing lists
Packing opens automatically once planning is done. Everyone sees what to bring — and what is already covered.
VHF briefing
The radio calls for your cruising area, prepared before you need them — from marina contact to routine traffic.
Logbook
Record legs, weather and moments as they happen. The voyage stays with you long after the lines are ashore.
