Sounds like you'll be okay. If you talk to Grant he will give you a good idea of what the charter companies will say and may even have some pull with them if you are borderline. I doubt the charter companies will give you much information. By that I mean they probably won't give you a list of what they require. Most likely each one will tell you send us your resume. Put down all of the skills you mentioned. Description of the boat you owned, what conditions you sailed in, including weather, over nights, were you in charge, docking, coastal areas with any challenges you were able to manage and navigate, etc. There is one company that has older power boats, mind is blank. They are pretty lenient but their boats are pretty big. I think you're choice will be Marine Max or Moorings. I don't see a problem getting their smaller power cat, 2 cabin. Worst case they might make you do the first day with a captain.
