I don't know much about AYC, but we did have our boat in charter with a different company in Anacortes for several years. We live 4 hours from Anacortes and originally planned to have our boat in charter for a couple of years as we thought our business commitments would slow down as we approached retirement. Instead, we became busier and had less boat time instead of more. Because of our schedule our boat was in charter for 6 years.
Like most things in life, there are positives and negatives to chartering. I was told by some that chartering would pay most of my expenses, and by others that chartering would destroy my boat. The reality in the Northwest is that a boat will probably be in charter for only 6-12 weeks. Most people want to charter in July or August, with some the first part of September. Our average was about 8 weeks a year. So you are not going to get enough business to pay all expenses, but you don't get the wear and tear on your boat like you do on boats chartered in warmer climates.
The busiest time for our business was June through August, so we used the boat in May and September, leaving July and August open for charter. If you want to use your boat in the prime months, you won't get many charters. We found that most of the folks that chartered our boat were older with a lot of boating experience, so we didn't have much damage to our boat. However, it did drive us a little crazy to come back and find that things were set up and stowed differently than we had left them.
One of the advantages of charter if you live at a distance is that the boat is always clean and ready to leave the dock when you arrive. If your schedule is tight, you can just walk off the boat and let the clean up crew deal with it. Most of the charter boats that I see in our marina are cleaner and in better shape than the average. Let me know if you have specific questions and I'll do what I can to help.
