The Promise 13'

Our Latest Model

Biel Tunnel Boats is pleased to announce the launch of our newly redesigned and updated 13' Promise model.

This new model includes a modern low profile built in deck windshield, flat floor space, increased storage, and an extended sponson running surface for enhanced stability, while still maintaining the great quality and style of the previous model.   

Our compact, fuel efficient 13' Promise model offers you high performance sports car-like handling even in 2-3' chop conditions. In addition, its small size makes both transportation and clean up a breeze.

The unique tunnel hull design of our boats is based upon principles developed in the hydroplane industry. The dual-sponson tunnel hull traps air coming in from the bow and compresses it towards the stern, causing you to ride on a cushion of air. As a result, the total wet planing surface area is next to nothing, creating a smooth, stable and fuel efficient ride. Sharp turns are no problem in these surface effect boats. They have tremendous maneuverability and turn as if on rails-flat and stable. The 13’ Promise can achieve speeds of over 50 mph with it’s Coast Guard rated 70hp engine.
