Preparing Your Boat for Safe Bluewater Voyages
Alexandra
A transoceanic passage planning metric often used by passagemakers is to budget at least 40–60 amp-hours per person per day and to verify that two independent charging systems can each meet that demand; without redundant charging (alternator, solar or hydro) a long offshore trip becomes a logistics exercise rather than an adventure.
Maintenance and spares: the backbone of self-reliance
Start with a methodical inspection: seacocks, engine, sail controls, rigging, electrics and electronic navigation units. Replace consumables whose service dates are near expiry—fire extinguishers, flares, lifejackets and the life raft—and record the dates in a dedicated maintenance log.
Common spares and storage strategy
Spare parts should be catalogued and sealed individually to prevent corrosion. Use labelled vacuum bags or zip-locks, and keep a master inventory in both paper and electronic form so a shore contact can advise from photos in an emergency.

| Category | Recommended Spares | Storage / Notes |
|---|---|---|
| Engine | Belts, impellers, gaskets, oil filter, fuel filter, extra oil | Waterproof box near engine bay; list with expiry dates |
| Steering | Emergency tiller, hydraulic fluid, linkage pins | Quick-access locker |
| Autopilot & Nav | Spare fluxgate, drive parts, backup mechanical windvane | Separate from primary nav locker |
| Sails & Rigging | Reefing lines, spare halyard, sail tape, Dynema repair cords | Dry sail locker, repair kit in cockpit locker |
Checklist (short)
- Service engine and generator; test for diesel bug and carry treatment
- Inspect standing rigging; consider a professional rigger report for insurance
- Fit an inline water strainer for engine cooling to trap impeller fragments
- Prepare an autopilot redundancy plan (electrical spare or windvane)
- Inventory electrical charging: alternator upgrade, solar, hydro or generator
Electrical systems and energy budgeting
Multiple independent charging sources reduce operational risk: an alternator with increased output, solar panels sized to daily consumption, and a hydro generator for downwind legs form a practical mix. Carry spare regulator and a portable battery charger as contingency.
Practical battery rules
Design for the worst-case: ensure each charging method could individually support essential systems (navigation, comms, bilge, pumps, instruments). Monitor battery health with a battery management system and carry a wiring diagram on board.
Sails, running rigging and chafe control
Long downwind legs demand a different sail inventory. Maintain redundancy for light-air and heavy-air sails and protect halyards and sheets from chafe. Daily rig surveys—move halyards a few centimetres and inspect chafe points with binoculars—are a simple habit that prevents failures.
Repair and mitigation
- Wide rolls of sail repair tape compatible with laminate and woven sails
- Manufacturer repair kits for lightweight aero sails
- Additional flip-flop block at masthead to reduce halyard chafe
Safety systems, protocols and drills
Safety preparation should be visual and procedural. Create clear yacht safety diagrams that show through-hulls, pumps, fire extinguishers, first-aid and MOB equipment. Colour-code diagrams for rapid reference: red for fire, blue for hull/pumps, green for first aid and MOB.
Lifejackets, life raft and MOB
Lifejackets should be self-inflating, at least 170N, with crotch strap, three-point tether points, a spray hood, light, reflective tape and a PLB or AIS beacon. The life raft must be ISO 9650 Type 1 Group A (or equivalent) with current inspection certificate and an over-24-hour service pack. Practice MOB drills regularly and ensure recovery methods are rehearsed and have the necessary clips, carabiners and blocks ready for quick deployment.
Communications and emergency use
Crew must know how to operate the VHF (including DSC), use satellite comms and access login details for services. Designate alternate operators and rehearse making a mayday and pan-pan call so that anyone can act when the skipper is incapacitated.
Medical, provisioning and crew management
At least one crew member should have advanced first-aid training and the medical inventory should include broad-spectrum antibiotics and robust analgesics. Telemedical support services are highly recommended for long passages.
- Provision staples: rice, pasta, pulses, tinned goods and long-life proteins
- Batch-cook and vac-pack meals to reduce galley time on rough passages
- Stock nightwatch treats and a variety of entertainment to maintain morale
Human factors
Agree watch systems in advance, respect circadian differences and deal promptly with interpersonal issues. Celebrate milestones at sea to keep morale high and use night watches for stargazing or celestial navigation training.
Who benefits: owners, charterers and renters
Whether an owner preparing their yacht or a charterer renting a boat, the same principles apply: verify service records, confirm safety equipment certificates, and ask for an inventory of spares and recovery gear. A well-prepared vessel reduces charter risk and increases the chances of a memorable, safe trip.
Forecast and call to action
The emphasis on practical, checklist-led preparation for bluewater passages is unlikely to change the global tourism map dramatically, but it does strengthen the niche market for experienced cruising holidays and offshore charters. For individual travelers and local marinas, better-prepared vessels reduce rescue callouts and create more reliable sailing itineraries.
