Keeldragger Sailing Offshore Toolkit gets you and your boat ready for blue water.
OFFSHORE READINESS — Work through a comprehensive 355-item passage checklist covering 26 systems: standing and running rigging, engine and drivetrain, watertight integrity, safety and survival gear, medical, provisioning, paperwork, weather planning, and more. Every item has a unique reference number, priority, disposition (To Do, In Progress, Blocked, Deferred, Complete, N/A), and room for your own notes. Every change is timestamped.
READINESS DASHBOARD — A heatmap shows readiness by category at a glance, weighted by priority, so open high-risk items stand out. Tap any tile to jump straight to that section. Export a color-coded Readiness Report PDF to share with your insurer, surveyor, or crew.
VESSEL DETAILS — Keep your vessel's registration, dimensions, appearance, engine, and tankage details in one place. They flow automatically into your reports.
FLOAT PLAN — Build a proper offshore float plan: crew list, leg-by-leg itinerary with dates and distances, communications and tracking, safety equipment, shore team contacts, photos of boat and crew, and clear "if overdue" instructions. Export a polished PDF for whoever holds your plan ashore.
Everything is stored locally on your device — nothing is uploaded.
