Why wintering in Mallorca is different
Most winterizing advice is written for northern Europe: frost, antifreeze in every circuit, boats under shrink wrap from October to April. Mallorca is not like that. Winters are mild, frost on the coast is practically unheard of and plenty of owners keep sailing on sunny days in January.
That doesn't mean you can lock the boat and forget about it. The real risks in the Balearics are different:
- Winter wind and swell. From late autumn the Tramuntana (north) and Mistral (northwest) blow more often, alternating with southerly and easterly spells. The north coast, including the bays of Pollença and Alcúdia, is exposed to northerlies and easterlies, while other harbours suffer more from southerly or easterly swell.
- Real storms do happen. During Storm Gloria in January 2020, around twenty boats in Port de Pollença were torn loose and ended up on the beach. In March 2017, two yachts sank in Port d'Andratx after wind and swell repeatedly pushed them against the dock.
- Sudden changes in water level. Balearic harbours can be hit by rissagas (meteotsunamis), sharp sea-level oscillations of tens of centimetres. In August 2026 they were recorded in Port d'Alcúdia, Port d'Andratx, Port de Sóller and Port Adriano. Lines that are too tight or fenders in the wrong place won't cope.
- Fouling that never stops. In warm Mediterranean water weed and barnacles keep growing through the winter, more slowly but steadily.
- Damp, sun and neglect. Condensation, mould, flat batteries, blocked cockpit drains and UV damage are what usually ruin a boat left alone for five months.
If you want the general, step-by-step winterizing routine (engine, freshwater system, batteries, interior), read our guide to preparing your boat for winter. This article focuses on the Mallorca-specific decisions and on how to organise things when you are not on the island.
Option 1: stay afloat in a marina
Many boats in Mallorca spend the winter in the water. It works well if your berth is in a well-protected marina and someone checks the boat regularly.
Pros
- You can use the boat on good days and during short trips to the island.
- No crane or travel lift, no storage fee on the hard, no blocking and propping.
- If you already pay for an annual berth, winter costs little extra.
Cons
- The hull keeps fouling, so you'll need a hull clean by a diver or a haul-out in spring anyway.
- The boat is exposed to storms, surge and chafe. Someone has to check the lines after every serious blow.
- Shore power left connected for months can feed galvanic corrosion if the installation isn't right (see galvanic corrosion on boats).
What to set up before you leave
- Double the mooring lines, add chafe protection where they pass through fairleads and use snubbers or line dampers.
- Leave enough slack for changes in water level and place fenders so they still protect the hull if the boat moves.
- Remove or tightly lash anything with windage: sprayhood, bimini, furling headsail (or at least add extra wraps and tie the sheets), dinghy on davits.
- Make sure the bilge pump works automatically and that its battery stays charged, through shore power or a small solar panel.
Winter berth prices vary a lot between Palma, Port Adriano, Andratx and the smaller harbours. Check our boat mooring cost guide for indicative ranges and look for berths and moorings in Mallorca.
Option 2: haul out and store on the hard
Hauling out for the winter is the classic choice for owners who won't use the boat until spring, and it's the natural moment for antifouling, anodes and underwater work.
Pros
- No fouling, no chafe, no risk of sinking at the berth.
- The underwater hull can be inspected, the hull and gelcoat can dry out, and spring jobs (antifouling, anodes, stern gear, seacocks) are done in the same yard visit.
- Easier for a mechanic or painter to work on the boat while you're away.
Cons
- Yard fees plus lift-out and relaunch. Look at the haul-out cost guide and the winter storage cost guide before you ask for quotes.
- A boat on stands in a windy yard still needs to be well propped and tied down.
- Some yards have rules about owner DIY work, outside contractors or working hours.
Where. The biggest concentration of yards and marine trades is in and around Palma, but there are also yards with travel lifts in the north (Alcúdia) and on the east coast, for example at Cala d'Or. If your boat is based far from Palma, a local yard can save you a delivery trip in autumn weather. You can compare boatyards and haul-out in Mallorca on Nautify.
Option 3: dry stack or indoor storage for small boats
For RIBs, tenders and small motorboats there are dry stack (rack) systems and covered warehouses on the island. Indoor storage protects against sun and salt, and in a warehouse without racks it's easier for technicians to work on the boat over the winter. Ask whether the price includes launching on demand if you want to use the boat on a visit.
When to book
October is haul-out and refit season. The best spots on the hard, slots for antifouling and the good mechanics' diaries fill up from early autumn, and owners who arrive in late November often get whatever is left.
- Book the haul-out date and the winter work list in September or October.
- Agree a relaunch date at the same time. Spring is just as busy, since everyone wants to be in the water by Easter or May.
- Ask for written quotes for each job before you leave. If something extra comes up (a seized seacock, a worn cutlass bearing), the rule should be: photos and a price first, work after your approval.
Antifouling and underwater work
If you haul out, winter is the time to deal with the underwater hull. In the Mediterranean most boats repaint every one or two seasons, depending on use and the product. Our antifouling paint guide explains the types (hard, ablative, silicone), and the antifouling cost guide gives indicative prices per metre. Ask the yard to:
- Pressure-wash the hull on lift-out, before the fouling dries hard.
- Photograph the hull, keel, rudder, propeller, shaft and anodes so you can see the condition from home.
- Check for blisters if your boat is GRP (see fibreglass hull osmosis).
- Replace anodes and service seacocks while the boat is out of the water.
If you stay afloat, arrange a hull and propeller clean by a diver before you plan to use the boat again.
What a local yacht manager does while you're away
For foreign owners, the most important person over the winter is often not the mechanic but the yacht manager (also called boat-sitter, caretaker or guardiennage service). A good one is your eyes on the island. Typical services:
- Regular visits to check lines, fenders, bilge, batteries, covers and ventilation.
- Extra checks after storms and weather warnings.
- Airing the boat, running the engine or generator if agreed, flushing systems.
- Coordinating trades: getting quotes, letting the mechanic or painter on board, checking the work.
- Organising haul-out, relaunch and spring commissioning so the boat is ready when you land.
What to agree in writing
- Visit frequency (weekly, fortnightly) and what happens after a storm warning.
- Photo or video report after each visit, sent by email or messaging.
- A spending limit above which no work is done without your written approval.
- Language you'll communicate in. Many professionals in Mallorca work in English or German, but don't assume it.
- Keys and access: who holds them, and whether the marina or yard has been told who is allowed on board.
- Invoices: itemised, with the trades' original invoices attached.

Mechanic, electrician and the rest of the winter work list
Winter is when the engine service, rigging check and electrical jobs get done without eating into the season. A sensible list to hand over:
- Engine service: oil and filters, impeller, fuel filters, belts, a look at the exhaust elbow and heat exchanger. See marine engine mechanics in Mallorca and the engine service cost guide.
- Batteries and charging: test capacity, check the charger and any solar regulator (batteries and electrical system guide).
- Standing rigging inspection if it hasn't been done in a few years.
- Deep clean and teak care before spring (boat cleaning cost guide).

Pre-departure checklist
Before you fly home, go through this list with the boat and, ideally, with your yacht manager:
- Lines doubled, chafe protection fitted, fenders checked (afloat) or boat properly propped and tied down (ashore).
- Sails, sprayhood and bimini removed or securely lashed. Halyards tied off the mast so they don't slap.
- Bilge dry, automatic bilge pump tested, cockpit drains clear.
- Seacocks closed (except those needed for cockpit drains), noted on a list for the yacht manager.
- Fuel tank topped up to reduce condensation, freshwater system drained or treated.
- Fridge emptied and left open, food and anything perishable removed.
- Cushions and textiles dry, raised or taken off, ventilation open and moisture absorbers in place.
- Batteries charged, unnecessary loads off, shore power or solar setup confirmed.
- Valuables, portable electronics and documents taken home (keep copies on board if the marina requires them).
- Insurance checked: does it cover the boat afloat or ashore in Mallorca for this period, and are there conditions about storms or visits? See our marine insurance guide.
- Contact list left with the marina or yard: your phone, your yacht manager, your insurer.
- Photos of the boat as you left it, inside and out.
FAQ
Does a boat in Mallorca need antifreeze for the winter?
Usually not on the coast, where frost is very rare. Many owners still protect the raw-water circuit if the boat will stand ashore for months, mainly against corrosion and stagnation. Follow your engine manufacturer's advice and ask your mechanic.
Is it safer to leave my boat afloat or on the hard?
Ashore removes the risks of fouling, chafe and sinking at the berth, but the boat must be well propped. Afloat is fine in a well-protected marina if someone checks the lines regularly and after every storm. Exposed harbours and swing moorings are the riskiest options for an unattended winter.
When should I book a haul-out in Mallorca?
As early as you can, ideally in September or October. Book the relaunch date at the same time, because spring is just as busy.
How often should a yacht manager check my boat?
Weekly or fortnightly is common, plus a visit after every storm warning. What matters most is that each visit ends with photos and a short report.
Can I do my own work in the yard?
It depends on the yard. Some allow owner work, others limit it or require approved contractors. Ask before you book.
