What is standing boat storage?
Standing boat storage is the practice of holding a boat upright on land, supported on stands, keel supports or a cradle, so it can spend the off-season or a maintenance period out of the water. The aim is simple: keep the hull in its designed shape, spread the boat's weight across stable supports, and make sure nothing can shift or topple.
A boat standing on land behaves differently from one afloat. In the water the hull is supported evenly by buoyancy; on land the weight is carried at a few points, so those points have to be chosen and rated carefully. Poor support concentrates load where the hull was never designed to take it, which can cause deformation that often goes unnoticed until the boat is back in the water.
Standing storage applies whether the boat is in a marina compound, a commercial boatyard or a private hardstanding. The principles are the same; only the scale and the responsibility differ.
KIPAC is a CE-documented European manufacturer of boat stands, keel supports and cradles, with capacities typically from 1 to 40 tonnes in structural steel (S355) and aluminium. For the wider UK context, see [Boat storage guide UK](https://kipacboatstands.com/resources/boat-storage-guide-uk/).

Types of support: keel supports, adjustable stands and cradles
Standing storage uses a few distinct types of support, often in combination.
Keel supports: Placed directly under the keel, these carry the principal weight of a keelboat and spread it over a larger area than side stands alone. For a sailing yacht with an external keel, the keel often carries a large share of the total weight, so the keel support is central to a stable setup.
Adjustable boat stands (side stands): The most common support for motorboats and sailing yachts. They adjust in height and, on some models, angle, so the rubber pad follows the curve of the hull and steadies it on each side. They are used in opposing pairs.
Cradles: Purpose-built frames that cradle the hull at several points. Used for heavier craft and vessels where standard stands are not sufficient, with capacity typically ranging from around 8 to 40 tonnes.
Ground protection: Steel plates or timber pads under the feet spread the load on soft ground.
Which combination suits a given boat depends on hull form, keel type and weight. For how this looks in a commercial setting, see [Boat park UK: how boatyards store boats and what to ask](https://kipacboatstands.com/resources/boat-park-uk/).

How to position boat stands correctly
Correct positioning is what makes standing storage safe. The principle is to balance the load and let the strong parts of the hull carry it.
Use opposing pairs: Side stands should be placed directly opposite each other so their loads balance across the hull. A stand on one side without its partner opposite pushes the hull sideways.
Let the keel carry the weight: On a keelboat, the keel or a keel support should carry the principal weight, with side stands steadying rather than lifting the hull.
Spacing and number: Spread the stands along the hull at the stronger points, typically near bulkheads or frames where the hull resists point loads best. As a guide, use at least 2 pairs under 6 m, 3 pairs for 6–9 m and 4 pairs for 9–12 m, with advice from a yard for larger boats.
Angle and pads: Set each stand so the pad sits flat against the hull and the load runs down the stand's axis. Rubber pads on every contact point protect the surface and spread the load.
Ground: Place stands on firm, level hardstanding, with plates or timber pads under the feet on soft ground.

Load capacity: matching stand ratings to boat weight
Every stand, keel support and cradle has a rated capacity, which is the maximum load it is built for under normal storage conditions. Matching that rating to the boat's weight is fundamental.
Know the weight: Start from the boat's displacement or all-up weight, not just its length. Two boats of the same length can differ significantly in weight.
Spread across supports: The weight is shared between the supports, but it is not shared evenly. The keel or keel support carries the principal weight on a keelboat, whilst side stands take a smaller, steadying share. Size the supports for the load each one actually carries, with a margin.
Never exceed the rating: A stand should never be loaded beyond its rated capacity. Documented load ratings, as on CE-documented products, give a clear basis for this judgement.
Margin and condition: Allow a sensible margin, and remember that corrosion or damage reduces the effective capacity of any support below its original rating.
For heavier craft, a cradle rated to the boat's weight may be more appropriate than side stands. KIPAC's range covers capacities typically from 1 to 40 tonnes. For budgeting the equipment, see [Boat storage cost UK](https://kipacboatstands.com/resources/boat-storage-cost-uk/).

CE documentation and what it means for commercial boatyards
For commercial boatyards and marinas that store other people's vessels, the choice of support equipment is not only about price and availability. Documentation, traceability and a clear statement of load capacity are central to the professional assessment.
CE documentation means a product has been assessed and documented against its nominal load ratings. In a professional setting – including a yard storing customers' boats – this documentation may be relevant to insurance, liability and the yard's own quality procedures. Local rules, insurance terms and a yard's own requirements vary, so it is worth verifying what applies in each case. CE documentation may be required by an insurer or by the yard's procedures rather than by a single universal rule.
For private owners CE documentation is not a legal requirement, but it is a quality signal: a stand without a documented capacity and construction specification gives little basis for judging whether it suits the actual load.
KIPAC manufactures CE-documented boat stands, keel supports and cradles in structural steel (S355) and aluminium, with corrosion protection by hot-dip galvanising or powder coating, capacity typically 1–40 tonnes, manufactured in Croatia (EU).

Common mistakes in standing boat storage
A few recurring mistakes account for most standing-storage problems.
Too few stands, or stands not in opposing pairs: An unbalanced setup pushes the hull sideways and concentrates load. Always use opposing pairs and enough of them for the boat's length and weight.
Leaving a keelboat on side stands alone: Without a keel support carrying the principal weight, the hull can twist over the winter. The keel should do the work; side stands steady it.
Ignoring the ground: Stands on soft ground without plates or timber pads can sink and shift, especially after rain or frost. Firm, level hardstanding is the starting point.
Missing or hardened rubber pads: Bare or perished pads concentrate load on the hull surface and risk gelcoat damage. Replace them.
Overloading or using damaged supports: Exceeding the rated capacity, or using corroded or bent stands, removes the safety margin. Inspect supports and never exceed the rating.
No winter inspection: Supports can settle or shift over months. Check them through the winter and again before launch.

Checklist
Checklist: safe standing boat storage
Adjustable side stands for the hull, a keel support to carry the principal weight on a keelboat, and a cradle for heavier craft where standard stands are not sufficient.
Place side stands directly opposite each other so loads balance across the hull. At least 2 pairs under 6 m, 3 pairs for 6–9 m, 4 pairs for 9–12 m.
On a keelboat the keel or keel support carries the principal weight; side stands steady rather than lift the hull. Never rely on side stands alone for a keelboat.
Size every support for the load it actually carries, with a margin, and never exceed the rated capacity. Documented load ratings make this judgement clear.
Firm, level hardstanding, with steel plates or timber pads under the feet on soft ground. Rubber pads, in good condition, on every contact point.
Check that nothing has settled or shifted through the winter, and again before launch, especially after storms or heavy frost.

FAQ
Standing boat storage means holding a boat upright on land, supported on stands, keel supports or a cradle, so it can spend the off-season or a maintenance period out of the water. The aim is to keep the hull in its designed shape, spread the weight across stable supports and make sure nothing can shift or topple.
Most boats use adjustable side stands in opposing pairs to steady the hull. A sailing yacht with an external keel also needs a keel support under the keel to carry the principal weight. Heavier craft may use a cradle. Steel plates or timber pads under the feet spread the load on soft ground.
Place side stands in opposing pairs so loads balance across the hull, spread along the stronger points near bulkheads or frames. On a keelboat let the keel or keel support carry the principal weight. Set each stand so the rubber pad sits flat against the hull, on firm level ground with plates or timber pads under the feet on soft surfaces.
Start from the boat's displacement or all-up weight, not just its length. The weight is shared unevenly between supports, with the keel or keel support carrying the principal load. Size each support for the load it actually carries, allow a margin, and never exceed the rated capacity. Documented load ratings make this judgement clear.
For commercial boatyards and marinas storing customers' vessels, CE documentation means the load ratings have been assessed and documented, which may be relevant to insurance, liability and the yard's own quality procedures. It may be required by an insurer or the yard's procedures, so it is worth verifying what applies. For private owners it is not a legal requirement but is a clear quality signal.
The most common mistakes are too few stands or stands not in opposing pairs, leaving a keelboat on side stands without a keel support, ignoring soft ground, missing or hardened rubber pads, overloading or using damaged supports, and skipping winter inspections. Each one removes part of the safety margin and risks hull damage or a toppled boat.
