- 🔹 Steel frames They are suitable for boats up to 1.5 tons, corrosion resistant (when handled correctly), but 30-40% heavier than aluminum, ideal for permanent operation.
- 🔹 Aluminum frames - 40% lighter steel, non-rust, but more expensive and less resistant to mechanical damage, optimal for boats up to 1 ton and those who often remove / install trailers.
- 🔹 Combined frames (steel + aluminum) is a rare but promising option, such as a steel base with aluminum crossbars, which reduces weight without losing strength.
It is important to consider and frame-frame:
- U-shaped They are universal and suitable for most boats.

- 📐 Width It depends on the shape of the boat, and 1.2-1.5 m is enough for PVC boats, and 2.2 m for boats with a wide hull.
- ⚖️ Load capacity Consider the weight of the boat + engine + equipment + margin of 20%, for example, if the boat weighs 800 kg, the frame must withstand a minimum of 1 ton.
| Type of boat | Recommended frame length | Minimum load capacity | Optimal material |
|---|---|---|---|
| PVC boats (up to 3.5 m) | 3.7–4.0 m | 500-700 kg | aluminum or steel |
| Aluminum boats (3.5-5 m) | 4.0–5.5 m | 1–1.5 t | Steel |
| Glass-plastic boats (5-7 m) | 5.5–7.5 m | 1.5–2.5 t | Anti-corrosion steel |
