Thinking Voyage is not on as firm financial footing as TMM and Moorings. That’s likely what the deal is. Will they survive and make good on keeping deposits on charters they cannot fulfil as scheduled? Possibly ..but who knows? My take..if they don’t have a boat available for a scheduled charter and you request a refund for a charter booked during that time..you are entitled to a full refund if you don’t choose to wait until later.
It would be wise for these companies to offer 10 days for 7 or a significant discount to book a charter later than scheduled. But not returning deposits on boats not available is unconciounsnable. ..or sign they are financially precarious.
The same company if indeed are forcing someone to take a different boat or a different time ..would in no way allow a chartered to change those items a few weeks out.
