Have performed power boat and sailing training over the years. Have been an ASA instructor, US Sailing instructor, and currently a full fledged sailing instructor with nauticed.org.
I have written many letters of proficiency for owners that they provide to their insurance company. Some times instruction can just be an hour or two, or a weekend cruising to some destination.
Concepts in training can fall into these categories:
- Close quarter maneuverying
- use of spring lines and fenders
- navigation
- fuel ups and pump outs
- anchoring
- deploying, retrieving, and operating dinghy
- machinery space
