Brett's Trailcraft group of companies manufactures aluminium trailer boats, boast trailers and caravans and sells them through five of his own retail stores and 27 independently owner retail outlets across Australia. With no experience in manufacturing, Mr Martin purchased a small, fledging aluminium boat company called Trailcraft five years ago. At the time, business’s two staff produced 10 boats a year. This manufacturing operation has into what Mr Martin says is the biggest producer of plate aluminium trailer boats in the world, with more than 200 staff producing 1,200 boats a year. And his Saltwater Marine sales outlet in Fremantle has been the biggest Mercury Outboard dealer in WA for the past five years. And the business has recently moved into caravans. Mr Martin spent 18 months and around $1 million on research and development, with Trailcraft now producing five caravans a week.
