Coastal Navigation

Coastal Navigation meets at The Riverboat on Tuesday evenings from 6 to about 8 pm. At the first class, we'll hand out the training chart, parallel rules, and dividers that you'll use for the homework each week, along with the textbook. At the third class, we'll hand out copies of the Eldridge Tide and Pilot Book that we'll use for tide and current problems both in class and in the homework.

We'll begin classes 2 through 6 by going over the homework from the previous week and reviewing the most important concepts and skills. So if you have to miss a class, you can download the Problem Set, read through the class slides and textbook, and be confident of catching up the next week.
