Quick answer: what 'laying up' means in the UK
Laying up is the traditional British term for taking a boat out of use for the winter and preparing it so it survives the off-season in good order. It covers protecting the hull, supporting the boat correctly if it is ashore, winterising the engine, and drying and securing the interior.
A boat can be laid up ashore (lifted out onto stands or a cradle at a yard) or afloat (left in a berth). Ashore is the thorough option for keel boats and larger craft, because it gets the hull out of the water; afloat is simpler but leaves the hull wet. This guide is the *procedure* — the tasks of laying up. For choosing *where* to store, and for the full storage overview, see the linked guides.

Lay-up ashore vs lay-up afloat
Laying up ashore means the boat is craned or hoisted out and supported on the hard for winter. It lets you scrub and inspect the underwater hull, renew antifouling, check the keel and skin fittings, and let the hull dry — the reason most keel-boat owners lay up ashore. The boat must then be supported correctly so months on the hard do not stress the hull.
Laying up afloat keeps the boat in its berth. It avoids the lift-out and keeps the boat accessible, but the hull stays wet, so antifouling and underwater checks wait until spring, and you depend on the boat staying sound and afloat unattended. Many UK owners choose ashore for a proper lay-up and afloat for convenience. Whichever you choose, the preparation tasks below still apply.

Step-by-step: preparing the boat
A typical UK lay-up runs in a logical order. First, the hull and deck: clean off growth soon after lift-out while it is still soft, inspect the gelcoat, keel and fittings, and plan any antifouling. Second, the engine: winterise it following the manufacturer's manual — this is the single most important mechanical job, and is covered in detail in the linked outboard winterisation guide.
Third, systems and interior: drain water systems to prevent frost damage, treat the fuel, remove or maintain the battery, and strip soft furnishings, lifejackets and electronics to dry storage. Fourth, ventilation: leave the interior able to breathe, because a sealed boat in the damp UK winter grows mould. Fifth, cover: a breathable cover or shrink-wrap with vents keeps rain out without trapping condensation. Work to a checklist so nothing is missed.
Guide
Supporting the boat ashore correctly
If you lay up ashore, how the boat is supported decides whether it comes through the winter unmarked. The principle is simple: spread the load and take the main weight in the right place. On a keel boat, a keel support (or the keel blocks of a cradle) carries the bulk of the weight under the keel, and side stands stabilise the hull without bearing the full load. On a motorboat, stands are placed around the hull to spread the weight.
Use enough stands of the correct, documented capacity, placed at strong points of the hull, and check them after the first weeks as the ground settles. A cradle can be a better choice for some boats, especially where storage is tight or the boat is restacked. KIPAC manufactures CE-documented stands, keel supports and cradles, EU-made and supplied to UK yards, with the configuration confirmed at quotation rather than assumed.

Common mistakes when laying up
Some lay-up mistakes show up every spring. Leaving the hull uncleaned after lift-out lets growth harden and makes spring work harder. Skipping or rushing the engine winterisation risks frost or corrosion damage to the most expensive part of the boat. Sealing the boat under a non-breathable cover traps moisture and grows mould throughout the interior.
Undersupporting the boat ashore — too few stands, the wrong height, or no proper keel support — concentrates load and can mark or stress the hull over months. Leaving E10 petrol untreated in the tank over winter risks ethanol-related fuel problems. A methodical lay-up — clean, support, winterise, dry, ventilate, cover — avoids nearly all of these. KIPAC can confirm suitable ashore-support equipment during quotation; the engine and chemical steps should follow the manufacturer's guidance.
Checklist
UK boat lay-up checklist
Scrub off growth after lift-out, inspect gelcoat, keel and skin fittings, plan antifouling.
Follow the manufacturer's manual; see the linked outboard winterisation guide for outboards.
Drain water systems against frost, treat fuel, maintain or remove the battery.
Keel support plus enough correctly rated side stands or a cradle; check after settling.
Remove soft furnishings and electronics; leave the interior able to breathe.
Breathable cover or vented shrink-wrap to keep rain out and condensation down.

FAQ
Laying up is the British term for preparing and storing a boat out of use for the winter. It covers cleaning and protecting the hull, supporting the boat correctly if ashore, winterising the engine, draining systems against frost, and drying and ventilating the interior. It can be done ashore at a yard or afloat in a berth.
Ashore gets the hull out of the water so you can inspect, antifoul and let it dry, which suits keel boats and a thorough lay-up. Afloat avoids the lift-out and keeps the boat accessible but leaves the hull wet. Many UK owners lay up ashore for hull care and afloat for convenience; the preparation tasks are similar either way.
Spread the load and take the main weight in the right place: on a keel boat, a keel support carries the weight under the keel and side stands stabilise; on a motorboat, stands are placed around the hull. Use enough stands of documented capacity and re-check after the ground settles. KIPAC confirms the configuration at quotation.
Leaving E10 petrol untreated over a UK winter can lead to ethanol-related fuel problems, so treating or managing the fuel is part of a careful lay-up. Follow the engine and fuel manufacturer's guidance for the right product and method. This guide gives general lay-up steps and does not recommend specific chemical brands or mixes.
Mould thrives in a sealed, damp boat, which is a real risk in the UK winter. Strip soft furnishings and store them dry, leave the interior able to breathe, and use a breathable cover or vented shrink-wrap rather than sealing the boat completely. Ventilation, not airtight covering, is the key to a dry interior.
