 The result was production of low-quality boats backed by a short warranty and poor customer service, leading to trouble with dealers and unhappy owners.Luhrs was forced to suspend his racing career and return to directly run the company, carrying out a restructuring, creating new work teams, extending the warranty from one year to five years and hiring Canadian designer Rob Mazza in 1991 to take over design and coordinate the production process.Mazza designed the Hunter 29.5 and its larger follow-up, the 336.
