Laying up for the summer

How to lay up a boat in Malta for the summer when you’re abroad — the checklist, what heat and UV do to an idle boat, and how to cover it properly.

What is a summer lay-up?

A summer lay-up is preparing a boat to sit unused through the hot months — typically because the owner is abroad — rather than through winter. In Malta it is as much of a risk as a winter lay-up: the boat faces months of strong sun, heat, dust and humidity with nobody aboard. The aim is the same as in winter: leave her secure, dry, clean and covered, and come back to a boat that’s ready to use.

Why summer is the harder lay-up here

Most lay-up advice is written for northern Europe, where boats come out of the water to escape winter. In Malta a lot of owners divide their year between the islands and somewhere else, and plenty of boats sit idle in July and August — the hottest, brightest, dustiest months of the year.

An idle boat in a Maltese summer bakes. The interior heats up with the hatches shut, upholstery and headliners suffer, varnish and teak dry out, and any damp left aboard turns to mould in the warm, humid air. Batteries discharge faster in heat. And nobody is there to rinse off the dust or spot a problem.

Afloat or ashore?

Many boats in Malta stay on their berth through the summer. That keeps the hull in the water and the boat in a marina with security and someone nearby, but it means marine growth continues and the boat is exposed to swell and to anything that goes wrong with mooring lines.

Lifting out removes the growth and swell issues, but puts the boat on a hot, dusty hard standing. Either can work. What matters is that the boat is prepared and covered for the conditions where she’ll actually be.

Who keeps an eye on her?

An idle boat should still be checked. That might be the marina, a yacht management company, a skipper or a friend with the keys. Agree who it is before you leave, how often they’ll look, and what they’ll do if they find a problem. A cover with a zipped door lets them get aboard without having to remove and refit it.

Step by step

Summer lay-up checklist

  1. Empty and clean

    Food, drink and anything that can spoil out. Fridge off and propped open. Clean and dry the interior thoroughly.

  2. Dry the bilges

    Pump and dry the bilge. Damp left aboard is what turns into mould in the summer heat.

  3. Power and batteries

    Leave batteries charged and on shore power or solar if possible; disconnect what isn’t needed.

  4. Lines and fenders

    Afloat, double up and check lines and chafe protection; ashore, check the cradle or stands.

  5. Water, fuel and engines

    Follow the engine maker’s lay-up advice; fresh-water systems drained or treated.

  6. Cover and ventilate

    A light-coloured, framed and vented cover over the whole boat, with a door for whoever checks her.

Before we quote

We scan it first. Then the price doesn't move.

For lay-ups we survey once the boat is settled — on the hard or on her berth. We measure the vessel, work out the frame, the film area, the vents and the doors — and the number you get back is the number you pay. No provisional sums, no “subject to access”.

Can you send a quote before I go?

Start from your phone

Send a photo. Get a straight answer.

Not every job needs a visit to get going. Send a couple of photos and tell us where she’s laid up, ashore or afloat, and when she goes back in, and an installer will tell you what’s involved — including when shrink wrap isn’t the right call.

  1. Photograph it

    Whole item in frame, plus one close-up of the access side.

  2. Send it over

    WhatsApp or email, with where she’s laid up, ashore or afloat, and when she goes back in.

  3. We come back to you

    Approach, timescale and a price, in plain English.

Questions

Common questions

Should I cover my boat for the summer in Malta?

If she won’t be used for more than a few weeks, yes. The summer sun and dust do more damage to an idle boat in Malta than almost anything else.

Will a cover trap heat inside the boat?

A properly built one reduces it. White film reflects the sun, the frame keeps the cover off the deck, and vents let hot air rise out.

How do I stop mould in a laid-up boat?

Leave the boat dry, ventilate it, and avoid sealing damp inside. Vents in the cover and moisture absorbers inside help in the humid months.

Can someone check the boat with the cover on?

Yes — ask for a zipped door. Whoever is checking can get aboard without disturbing the cover.
