I have completed a few long distance personal boat deliveries. The last one was from Lake Michigan to Ct. As others have said, take your time and enjoy the sites. 10 kts is very comfortable in almost any seas. An autopilot will be a great asset. A lot of the information would be based on your own comfort level. Plan for the worse, have paper charts, you can "rent" an Epirb thru BoatUS for the journey at a very reasonable rate. We traveled an average of 8 hrs per day for 5 weeks.
On your journey, most ports are off of the beaten path, so stops will ad to your travel time. A responsible and knowledgeable crew will be another plus. In the famous words of Captain Ron, "If stuff is going to happen, it will happen out there".
Have extra fuel filters, some belts, hoses, tools, load check all of the batteries and not with just a volt meter.
