Proper storage of small vessels is not just a matter of convenience, but a critical factor in the longevity of the hull. boat-board avoids deformation of the bottom, prevents the formation of "bubbles" on fiberglass and protects aluminum seams from constant stress.
Owners often underestimate the role of a quality slipper, relying on random stops or simply leaving the boat on wheels, an approach that can be expensive to repair as early as next season, especially if it is heavy fiberglass, which, when uneven load, is prone to irreversible changes in geometry.
In this article, we will discuss in detail what types of supports are, how to calculate load points and whether it is worth spending time on independent construction or better to purchase a ready-made factory version.
Why you need a professional storage store
The main function of the slip is to distribute the weight of the boat evenly, and when the boat is standing on a flat bottom or on an uneven surface, high pressure points arise. PVC This is fraught with rubbing the fabric about the micro-squamousness of the floor, and for FRP (glassplastic) - the occurrence of internal microcracks in the matrix.
Metal boats, especially from lambLong-term storage on uneven surfaces can lead to the bottom "leading" and, when launched, the seams will be impaired. The stand excludes contact of the bottom with aggressive environments such as concrete, asphalt or damp earth.
Using a dedicated support makes it easier to preserve and deconserve, so you don't have to look for bars, bricks or sandbags to fix your position, but you have a fixed or mobile structure that's always ready to take the boat on board.
Design features of different types of slips
The market offers many solutions, from simple frames to complex engineering systems, depending on the type of boat you have and the conditions in which it will be most of the year. loading capacity and the material for making supports.
Wooden structures are popular among DIY enthusiasts, cheap and easy to assemble, but require regular antiseptic treatment, and metal frames are stronger but corrosion-prone unless high-quality powder paint or galvanizing is used.
⚠️ Warning: When choosing a metal stand, make sure all welds are cleaned and painted. Sharp edges of metal can damage the sides of an inflatable boat if handled carelessly.
There are also modular systems made of plastic or composites that don't rust, rot, and clean easily, but they often cost several times more than homemade systems, making them the lot of professional clubs or owners of expensive equipment.
Comparison of materials
The advantages of wood are: cheapness, affordability, ease of processing. Cons: rotting, deformation from moisture, fire hazard. The advantages of metal: high strength, durability, weldability. Cons: weight, risk of corrosion, complexity of fabrication without welding skills.
Calculation of support points and loads on the shell
The most critical mistake in building or choosing a stand is the wrong location of the reference points. The boat body is not a monolithic beam, it has a complex geometry. The center of gravity will shift and the boat will flip over. along with the equipment stored inside.
For keel boats, the main footholds should be the areas of the frames, and it is in these places that the hull is most rigid, and leaning on flat areas between the frames will lead to a deflection of the skin under its own weight.
- 📏 Forehead: The support should be immediately behind the forehead, supporting the keelson.
- 📏 Aft portion: Support is needed under the transom, but not at the edge, so as not to create leverage.
- 📏 Middle part: For long boats (more than 4 meters) a third support is required in the midfield area.
When calculating the load, take into account not only the dry weight of the case, but also the weight of the installed equipment: outboardThe safety of the support shall be at least 30% of the calculated weight.
Use soft inserts made of rubber or thick foam in the contact areas of the metal of the support with the hull of the boat, this will prevent scratches and scuffs.
Instructions: how to make a stand for a boat yourself
Building a slip yourself is a great way to save money and get a design that fits perfectly the dimensions of your boat. You will need to work with a welding machine or power tool if you choose a wooden option.
And the process starts with design, and you measure the length, width and height of your boat, and you draw a sketch from that data, and you get the distances between the crossbars. geometry The frame will correspond to the shape of the bottom.
☑️ Tools for creating a slip
If you use a profile pipe, cut the workpieces according to the drawing. It is better to build on a flat area using magnetic charcoal to fix right angles. Welds must be solid, without burns, to withstand vibration during transportation, if the stand is mobile.
An approximate calculation of the length of the sidewall of the frame:
L_frames = L_boats + 20 cm (spare on each side)
H_supports = H_board + 15 cm (for ease of work)
Once you've assembled the frame, you need to put the top supports in the form of a "P" or a "T" with a soft material on the top bar, and the final step is painting, and use the metal soil and two layers of enamel to protect you from moisture.
Comparison of materials: wood, metal or plastic
The choice of material determines the durability and cost of your design, and each option has its advantages and disadvantages, which you need to weigh before starting work or buying.
| Materials | Strength | Structure weight | Term of service | Difficulty of manufacture |
|---|---|---|---|---|
| Tree (pine/spruce) | Medium | Light. | 3-5 years | Low. |
| Steel (profile) | High. | Heavy. | 10+ years | Medium (welding required) |
| aluminum | High. | Very light. | 15+ years | High (needs argon) |
| Plastic (ready) | Medium | Medium. | 10+ years | Not applicable (purchase) |
Wood is a great choice for temporary or seasonal solutions inside a dry garage. Metal is indispensable for outdoor storage, where resistance to wind and precipitation is important. Aluminum is ideal if the stand is often planned to be carried in a trailer with a boat.
⚠️ Warning: Never use materials containing copper or its alloys in direct contact with the aluminium hull of the boat to support the boat, which can trigger electrochemical corrosion.
Features of storage of boats of different types
Other materials of the housings require an individual approach. Inflatable boats PVC can't be stored in compressed condition on sharp corners of stands, and it's better to use wide lozenges or to hang in a pumped state if space allows.
Fiberglass boats are afraid of point loads, and they are optimal for pads with adjustable screw supports that allow you to accurately set the boat in levels, repeating the curves of the bottom, this is especially important for racing or high-speed models, where broken geometry affects driving performance.
The main rule of storage: the boat should stand so that water can flow freely from it, and so that there are no pockets for snow and rain inside.
Metal boats require condensation protection. There must be a vent between the metal of the hull and the support of the support. The use of rubber mats or wooden pad bars is a prerequisite here.
Frequently Asked Questions (FAQ)
Can I keep a boat in winter on wheels without a stand?
Wheel storage is only allowed for short periods of time, and long periods of narrow wheels cause transom and bottom to deform, and wheels can be lowered or dryed by frost, and the boat should be moved to a slipway.
What angle of inclination is needed for a stand?
The optimal is a slight tilt towards the stern (about 5-10 degrees), which provides flow of melt water and condensate through the drainage holes, preventing the water from freezing inside the enclosure in winter.
Do I need to remove the motor when stored on a stand?
Yes, the outboard motor has to be removed, and its weight creates a significant lever per transom, which can cause it to break off or crack, and the motor is stored separately in an upright position.
How to protect a wooden stand from rotting?
Use special impregnations for wood in contact with the ground and moisture. Regularly check the condition of the tree and update the coating if necessary. You can also use a ruberoid as a gasket between the tree and the ground.
