well Andy...this is what the op WROTE:
My husband and I are dreaming about buying a boat.
We never had one and we don't know anything about the subject.
do you think they should jump right into the 50 foot twin motored boat club??
I have had driven all sizes up to about a 30 footer... and the bigger they get the harder they are to handle. just getting them out of the marina is difficult sometimes....it is hard to keep the boat from banging into things, because of all the momentum a big boat has.
take the tide and some current and some wind....and a big boat.....and a newbie.....in a narrow channel running out of the marina....
hey it is real life and a huge issue for a first time boater.....
but I have never sold boats( for a living) nor have I have driven 100 footers, so maybe I should shut up.....

all the best to the OP
