01 Pre-sail checks
Inspect rig, seacocks, bilge, and weather; brief crew on roles and MOB plan.

Quick answers
Which local authority or corridor rules matter for this type?
Start with the local lens: type approval, operator licences and the hubs named on this page — not a single global checklist.
Is this a buying guide?
No. Tool-Lifes /vehicles is an educational atlas. It explains history, systems and culture without affiliate rankings.
Are the scores official?
No. The six scores are relative editorial 0–100 marks across the twenty-four types on this site.
Where do the photos come from?
Lead images resolve from Wikimedia Commons via Wikipedia titles on the English masters, with licences recorded on the credits page.
Why metric units?
Metric is the default. Regional notes (US customary, local brand culture) appear in culture and market chapters.
How is this different from a wiki article?
Each type gets seven fixed-depth chapters, comparable scores and cross-type labs — structured for browsing, not a single freeform page.
Operating a Sailboat is a closed loop: sense, decide, actuate, and stay inside certified envelopes.
Principles and steps here are physics-first; brand procedures differ, but the envelopes are shared.
Principles
Apparent wind
Boat speed shifts wind angle—upwind VMG depends on pointing and sea state.
Righting moment
Heel increases until buoyancy and ballast restore equilibrium or capsize occurs.
Polar curves
Speed vs wind speed guides reef timing and sail selection.
Drag trade-offs
Clean hull and prop feathering beat fouling when sailing in light air.
Tidal strategy
Current with or against the hull changes SOG more than sail trim alone.

Operating steps
02 Cast off & motor
Use auxiliary to clear dock; hoist sails when channel opens.
03 Beat or reach
Trim sheets and traveler; watch gusts and adjust reef early.
04 Navigate & log
Plot fixes, monitor AIS traffic, and record hourly progress.
05 Harbor approach
Furl or douse early; motor final leg if congestion demands.
06 Secure & inspect
Cover sails, flush salt, and check chafe points after docking.
Hard limits
Wind & sea state
Crew skill and boat rating cap safe offshore days more than hull length alone.
Draft & clearance
Keel depth limits anchorages and canal routes.
Right-of-way rules
COLREGS govern encounters; sail does not always have stand-on status.
