Boats run on more than gasoline or diesel fuel. You can’t buy one without reading the fine print, and you can’t keep its systems running without some basic knowledge. That’s why the people that bring you TrawlerFest are offering four free seminars at the Yachts Miami Beach Show next week.

The Care & Upkeep Of Your Marine Generator Set

Your boat’s generator does a lot, but how well do you understand it? Northern Lights factory trainer Joe Maas will present a 45-minute seminar to explain generator service and maintenance. He will also discuss proper genset sizing and reasons for using the right coolant and lubricating oil. Attendees should learn everything they need to know to maximize their enjoyment of life aboard by ensuring that they always have the power they need. 11:30 a.m. – 12:15 p.m.

Marine Financing & Insurance

Phil Hawkins of Sterling Associates & Total Dollar Finance explains the basics of obtaining a loan to buy a boat and what you need to know about marine insurance. 1:30 p.m. – 2:15 p.m.

Keep Your Cool: Sizing, Service & Upkeep of Your Vessel’s Air Conditioning System

For many boaters, particularly in tropical climes, the biggest challenge is keeping cool. Shaun Hall, technical global sales director for Technicold Marine HVAC, will spend an hour explaining how to size a boat’s AC system, its basic operation and what you need to know about how to keep it running properly and effectively. 2:30 p.m. – 3:15 p.m.

Introduction to PC Navigation

PC-based marine navigation has revolutionized the way boaters plan and navigate voyages. PC-based navigation systems are easier to use and offer a more comprehensive user experience and sophisticated tools than what is available on a dedicated plotter, according to Rose Point Navigation Systems. Jeff Hummel of Rose Point, an electronics contributor to PassageMaker magazine, will cover all the basics, including software, choosing a program, charts and satellite and aerial imagery. 3:30 p.m. – 4:15 p.m.
