Which wheel for a boat launching trolley?

Choosing the right wheels for your launching trolley is essential to make handling easier, protect your boat, and ensure effortless launching. Below are the key points to help you understand, assess your needs, and choose the most suitable wheels.

Understanding the importance of the wheels

Launching trolley wheels must :

• Support the weight of the boat + the maximum load
• Roll easily over different surfaces (sand, gravel, grass, hard ground)
• Resist water, salt, and abrasion
• Provide good stability and maneuverability

1. Assessing your needs

Before choosing wheels, identify :

Total weight to be supported

• Weight of the boat + equipment
• Weight of the trolleys itself

Each wheel must be able to support part of this load without deforming

Type of surface used

Soft sand/beach

Gravel/uneven ground

Asphalt/hard surface

Grass/soft terrain

Frequency of use

• Occasional
• Frequent
• Intensive

2. Types of wheels and their uses

Solid wheels (polyurethane/rubber)

• Advantages : robust, puncture-proof, minimal maintenance
• Disadvantages : less comfortable on very uneven terrain
• Ideal for : beaches with a slight slope, hard surfaces

Wide solid wheels provide better load distribution on soft sand.

Balloon wheels (inflatable tires)

• Advantages : excellent grip, smooth rolling, good load distribution
• Disadvantages : maintenance required (pressure checks), risk of punctures
• Ideal for : soft sand, grass, uneven terrain

Tip : slighty under-inflate for better flotation on sand.

Wide « all-terrain » wheels

• Treaded profile, wide section
• Good compromise for mixed terrain
• Ideal if you use both beach and uneven spaths

Prefer stainless or aluminium rims to resist marine corrosion.

3. Wheel size and width

The wider the wheel, the better the weight distribution-especially useful on beaches, soft sand, or mud.

• Small wheels (< 200 mm) : limited mobility on sand
• Medium wheels (200-300 mm) : good compromise
• Large wheels (> 300 mm) : excellent on beaches and soft terrain

4. Load capacity

Each wheel must be able to support :

• The total weight of the trolley and boat divided by the number of wheels, with a safety margin

5. Usage tips

• Regularly check tire pressure (if inflatble)
• Rinse with fresh water after use in a marine environment
• Grease or lubricate axles and bearings
• Store wheels out of direct sunlight to extend their lifespan

6. Common problems and solutions

Hard to push on sand ?

Tires too hard or wheels too narrow  switch to wider or inflatable wheels

Wheels slipping or sinking ?

Surface too soft  use balloon or ATV wheels

Oxidized or seized wheels ?

Rinse after each use and lubricate the bearings
