Propeller Sizing Seminar

Spring in Virginia! Join us for a two-day propeller sizing seminar in Virginia Beach, Virginia on April 23-24. The seminar - Fundamentals of Propeller Sizing (with PropExpert) - is for everyone who sizes and analyzes inboard propellers for all boat types, from large work boats to smaller "go-fast" boats. The seminar is being hosted and sponsored in part by Wildcat Propellers of Chesapeake, Virginia (www.wildcatprops.com).

Course description
The seminar will be in two parts, and is suitable for all levels of experience in propeller sizing. Although HydroComp's PropExpert software is used to illustrate each topic, you do not need PropExpert to benefit from the seminar. All participants will receive a course packet with the seminar curriculum, as well as a variety of reports and resources.

We begin with a general discussion of fundamental propulsion relationships, then build an understanding of the propeller sizing objectives and processes, and finish with actual case studies where participants will be challenged to solve some problems. At the conclusion of the seminar, there will be ample time for participants to present and discuss some of their current projects.

Continental breakfast and lunch are provided each day.

Why attend?
Conducted by Don MacPherson, HydroComp's Technical Director, our training seminars are an outstanding value. You will leave with a new understanding of propeller performance and be better able to size successful applications for your clients and customers. As customers become more assertive in seeking quality answers to their problems, you will need to be able to provide these answers in a reliable and professional manner. These two days will help you not only minimize the risk of sizing poor installations, but you will learn how to analyze an application and be in a position to provide just the right solution - one that is quick, reliable and cost-effective.
