Whatever boat you decide on........ eventually you will be reciting those infamous words from the "Jaws " movies .....
"We need a bigger boat ".
As Regulo says .... "don't rush into taking second best" think long and hard about what you want to do with the boat, where you want to take it and with how many people, what facilities you require and how long you are going to stay on it.(these points will dictate how much room you need........
But most importantly see and go on as many boats as you can..........
Good Luck...................
