Larry Wieber's Aluminum Chambered Boats Inc. (ACB) has maintained a low profile during its first four years of operation. With a growing demand for security craft, and ACB's stellar performances in front of government buyers, his company's success is now Bellingham, Washington's worst kept secret. Personal sacrifice and pain often accompany success. Larry Wieber never knew the pain part would be literal, not figurative. In the process of helping a television production company prepare a story on his unique craft before bad weather stopped filming, Wieber badly crushed one of his fingers while rolling one of his boats off its trailer.
