My question is...who is them? Your young ladies? If it is then be sure they can swim good. That way they will be at ease on the water
I guess it would depend on where you are located when you ask how can you get out with them more. Also their ages would be a factor, and what do you consider economical?
You could always buy a 20ft, or so boat for very inexpensive, and sail when ever, and where ever you want. Most likely it will be trailerable, and that opens up a lot of territory for the price
of gas. In your mind's eye what would you like to see happen? A family
that plays together stays together most of the time.........
There are no dumb questions!
