Why a Pre-Sail Routine Matters

Most incidents afloat are not caused by spectacular failures. They come from a shackle that worked loose, a fuel filter half-clogged with diesel bug, or a seacock left closed after a winter lay-up. A short, disciplined walk-around before you slip the mooring picks up the vast majority of these problems while you are still alongside, where fixing them is straightforward rather than dramatic.

The routine below takes perhaps twenty minutes on a familiar boat and rather longer at the start of the season. Do it in the same order every time. Repetition is what turns a checklist into instinct, and instinct is what you rely on when you are tired, hurried, or keen to catch a tide.

Hull, Through-Hulls and Deck

Start at the stern and work forward, looking at the boat as if you had never seen her before. Check the hull-to-deck joint, stanchion bases and pushpit for cracks or movement. Look for rust streaks, which often betray a failing fitting beneath the gelcoat. On a drying mooring, use the walk down the pontoon or causeway to spot blisters, damage to the keel, or a rudder that has developed play.

• Confirm every seacock operates freely and is set correctly. Engine intake open, heads outlet closed where regulations require, sink drains as needed.
• Check hoses and double hose clips. A perished hose below the waterline is a serious matter; replace anything that feels hard, cracked or spongy.
• Inspect the propeller, shaft and anode. A wasted anode is cheap insurance and easy to swap alongside.
• Look at the deck for standing water, blocked scuppers and loose fittings. Clear the cockpit drains.
• Check guardrails, jackstays and lifelines. Tension the rigging screws, split pins taped, no sharp edges where a tether might chafe.

Rigging and Sails

Rigging checks are about looking up as well as pulling hard. Walk around the mast and sight up the spar. Anything that looks out of column, or a bend that was not there last time, deserves attention before you hoist.

• Run your hand along the shrouds and stays. Feel for meat hooks, broken strands or rust staining at the terminals.
• Check the split pins and rigging screws one by one. Tape them if you have not already. A lost split pin can cost you a mast.
• Inspect halyards, sheets and reefing lines for chafe where they pass through blocks or over the coachroof. Re-route or end-for-end anything suspect.
• Hoist the mainsail and headsail at the mooring if conditions allow, or at least flake them and check the luff and leech. Fit the reefing lines properly and mark them.
• Confirm the furling drum turns freely and the furling line is led cleanly. Check the topping lift and lazyjacks.

Engine and Fuel

Engine problems are the single most common reason a day sail ends early. Spend five minutes here and you will beat most of them.

• Lift the engine cover and look for leaks, loose belts and chafe. Check the alternator belt tension with a firm thumb; about 10mm of deflection is a reasonable guide.
• Check the oil level, coolant level and the raw-water strainer. Clean the strainer if there is weed or grit in it.
• Inspect the fuel filter for water or debris. If you have not changed it this season, change it. Carry spares and know how to bleed the system.
• Run the engine in neutral for several minutes. Listen for changes in note, watch for a steady exhaust and check that cooling water is discharging.
• Confirm the stern gland is not dripping excessively and that the shaft turns without binding.

Electrics, Navigation and Safety Kit

Electronics fail quietly, so test them rather than assuming. Switch on the plotter, the VHF, the depth sounder and the autopilot. Check that the GPS has a fix and that your waypoints for the day are loaded and sensible.

• Check the battery voltage and confirm the charging circuit works with the engine running.
• Test the VHF on low power and, if you can, arrange a radio check with a nearby station or another boat.
• Verify navigation lights, deck light and torch. Replace batteries in handhelds.
• Confirm lifejackets are serviceable, crotch straps fitted, and that you have a harness and tether for each crew member.
• Check flares are in date, the first-aid kit is stocked, and the fire extinguishers are in position with gauges in the green.
• Look at the weather forecast one more time and note the tidal stream for your passage. Write down the times of high and low water.

Briefing the Crew and Leaving the Mooring

Before you cast off, gather everyone for two minutes. Explain where you are going, roughly when you expect to arrive, and what each person will do. Show them where the lifejackets live, how the radio works, and how to stop the engine in an emergency. Keep it brief but make sure nobody is guessing.

Then run the departure sequence: start the engine, check the cooling water again, brief the mooring lines, confirm the depth and the wind, and agree who is doing what. Slip the lines, motor clear of the trots, and only then start setting sail.

None of this is clever, and that is exactly the point. A steady, unhurried routine before you leave the berth means the interesting parts of your day sail are the wind, the coastline and the company aboard, rather than the problem you could have found alongside.
