Quick answer: how the three differ
A keel support carries the boat's weight under the keel; a boat stand steadies the hull from the sides and stops it tipping; a cradle is a single framed structure that combines keel bearing and side support in one unit shaped to the hull. They are not really competitors — most boats ashore use a keel support (or cradle base) to carry the load plus side stands to steady the hull.
The simplest way to think about it: keel supports and cradles carry weight, side stands provide stability. A boat resting only on side stands with no keel bearing is wrong; so is a keel support alone with nothing steadying the hull. The decision is usually which combination, and in what capacity, rather than one versus the others.
This guide compares the three and how to choose. For the two-way cradle-vs-stand question see when to use a boat cradle, and for keel bearing in depth see the boat keel support guide — this article ties all three together rather than repeating them.

What each one does
Each support type has a distinct role, and understanding the role is the key to choosing.
A keel support sits under the keel and carries the major share of the boat's weight down through the strongest part of the hull. It is essential for keel boats and the foundation of safe blocking. A boat stand (side stand) bears against the hull sides on a padded top and is adjusted to steady the boat and prevent it tipping or rolling — it stabilises rather than primarily carrying weight. A cradle is a purpose-built frame, often shaped or adjustable to the hull, that combines keel bearing and side support in one transportable structure, useful for repeat storage of a known boat or for handling.
So keel supports and cradles are about load path; stands are about stability. A motorboat with a flatter run might rest on a cradle or on stands plus keel blocking; a sailing yacht needs dedicated keel support plus side stands. The right answer follows the hull, not a preference for one product.

Comparison table: stand vs cradle vs keel support
The table sets the three side by side on their role and best use. In practice they combine; the table shows what each contributes.
| Criterion | Boat stand (side) | Keel support | Cradle (combined frame) |
|---|---|---|---|
| Primary role | steady the hull, prevent tipping | carry weight under the keel | carry and steady in one frame |
| Load path | side of hull (padded) | through the keel | keel + sides combined |
| Best for | steadying most hulls | keel boats, main load bearing | repeat storage, handling, known boat |
| Used alone? | no — needs keel bearing too | needs side stands to steady | yes (self-contained) |
| Adjustability | height/angle per stand | height under keel | framed, sometimes adjustable |
| Typical pairing | with keel support/blocking | with side stands | standalone or with extra stands |
The pattern is clear: stands steady, keel supports carry, cradles do both in one unit. Most ashore setups are keel support plus side stands; a cradle replaces that pair with a single shaped frame where it suits the boat and operation. Capacity for whichever combination must match the boat's weight.

How to choose for your boat
The choice is driven by hull type, weight, how long and how often you store, and whether you also need to move the boat.
Start with the hull: a keel boat (most sailing yachts) needs dedicated keel support plus side stands, and a cradle is a strong option for repeat storage. A planing powerboat with a flatter bottom is often well served by stands with keel blocking or a cradle shaped to its hull. Next, weight sets the capacity of every element — supports must be rated comfortably above their share of the load. Then consider use: a boat stored in the same spot each winter and occasionally moved may justify a cradle; a yard storing varied boats may prefer the flexibility of stands plus keel supports.
Whatever the mix, the load must run through the keel, the sides must be steadied, the supports must be rated and set on firm ground, and contact points should be padded. KIPAC manufactures CE-documented boat stands, keel supports and cradles with traceable capacity, and configures the right combination to the boat during quotation — see the boat keel support guide for the load-bearing side.

Common mistakes choosing supports
Most support mistakes come from treating the three as interchangeable rather than complementary.
The first is relying on side stands alone with no keel bearing, so the hull is steadied but its weight is not properly carried — a classic cause of instability. The second is the reverse: keel support with too few or no side stands, leaving the boat liable to rock. The third is choosing by price or habit rather than hull type and weight, for example forcing a deep-keel yacht onto a setup meant for a flatter hull. The fourth is using any of them below the boat's weight, or on soft, uneven ground.
The fifth is ignoring pads, letting hard contact mark or stress the hull. The reliable approach is to match the combination to the boat — keel bearing to carry, side stands to steady, or a cradle that does both — all rated and correctly set. KIPAC supplies all three as CE-documented equipment sized to the boat during quotation. For the two-way cradle-vs-stand decision, see when to use a boat cradle.
Checklist
Choosing boat supports: decision checklist
Note whether it is a keel boat or a flatter planing hull, as this drives keel support and cradle choice.
Use the loaded weight including fuel, water and gear to size the capacity of every support element.
Plan keel support or a cradle base so the weight runs through the strongest part of the hull.
Include enough side stands to stabilise the hull and prevent tipping or rolling.
Choose a cradle for repeat storage or handling of a known boat, or stands plus keel supports for flexibility.
Ensure each element is rated above its share of the load and set on a firm, even surface.
Confirm padded contact points so supports do not mark or stress the hull.

FAQ
A keel support carries the boat's weight under the keel; a side boat stand steadies the hull and stops it tipping; a cradle is a single framed structure that combines keel bearing and side support shaped to the hull. Keel supports and cradles carry weight, stands provide stability. Most boats ashore use a keel support plus side stands, or a cradle that does both jobs in one unit.
For most boats, yes. The weight should run through the keel on keel support (or a cradle base), while side stands steady the hull and prevent it rocking or tipping. Side stands alone do not properly carry the load, and a keel support alone does not steady the boat. A cradle is the exception, as it combines both functions in one frame.
Neither is universally better — they suit different situations. A cradle is convenient for repeat storage or handling of a known boat because it combines keel bearing and side support in one transportable frame. Stands plus keel supports are more flexible for a yard storing varied boats. The right choice depends on hull type, weight, how you store and whether you also move the boat.
A keel boat such as most sailing yachts needs dedicated keel support plus side stands, with a cradle a strong option for repeat storage. A planing powerboat with a flatter bottom is often served by side stands with keel blocking or a cradle shaped to its hull. In both cases the load runs through the keel, the sides are steadied, and every element is rated to the boat's weight.
Yes. KIPAC manufactures CE-documented boat stands, keel supports and cradles with traceable load capacities and S355 structural steel. Because the three are usually combined rather than used alone, KIPAC configures the right combination — keel bearing to carry, side stands to steady, or a cradle that does both — to the specific boat's weight and hull during quotation.
