Hatteras for big family

[Smart555]

Hello everyone!

We’re family of 6: 42, 38, 12, 9, 3,5 and baby boy looking for a suitable boat for us to try living aboard.
Because our older kids go to school and we’re not ready for homeschooling yet our plans are going to make weekend passages , but the main aim is to travel the Bahamas and Caribbean for 2-3 mounts in summer vacations. Actually we don’t like just stay at Marina. We prefer to move from place to place exploring new!

Our budget is araund 200-220k and we consider Hatterras 58 , 54, 53 1983-1986Y
The best for options for us to have 3 staterooms, open or semi open aft desk , and possibly offshore passages.

We have some questions for happy Hatteras owners:

Which of this boat more suitable for us?
What do we need to pay attention for choosing the boat?
How match is maintainins cost in Year?
Is it possible for this boats to cruise blue water for 10 hours a day in houl speed around 9knots?What about fuel consumption?
Is it possible to make comfortable long offshore passage from Fort Lauderdale to Caribbean?

We also considering Hatteras LRC. But in our budget we can afford only the boat 10 years older and most likely not bigger then 48”LRC. We understand that probably it would be better for us but we’re not sure if 40 years old downsized boat it worth the money we could spend for newer more comfortable boat.

Thank you in advance for your opinions!
