We are planning our first long range cruise this summer. We have Viking 44 Aft cabin motor yacht with twin 6-71 Detroit Diesels. Our cruise plan is from New York to Miami. Would like your comments or suggestions. Will this be a fairly easy cruise along the coast? What should I plan on for time cruising about 5-6 hours per day? 8-10 kn. Is there an app or website I can use to determine or project the cost of this trip? Thanks for your input!
