Support for your inflatable

A pair of 1.4m carpeted bunks and two keel pad supports provide the trailer's hull support. We can help check the setup against your boat's tube spacing, transom position and loaded weight.

A 10ft inflatable is approximately 3.05m long, within the manufacturer's stated length range. Send us your boat's make and model so we can confirm the support arrangement before ordering.
