We are looking for a board for flat water work with 1 or 2 kids on as passengers. It will be used on the lake 99.9% of the time with maybe 1 or 2 ocean paddles a year. When on a family paddle my wife would use it with the kids on and I will ride a 12' board. Is a 14' board going to be big enough or should I be focusing on the longer boards.

What are my choices... DC's, Laguna bay, Lahui Kai? How do they all compare? I would prefer to buy second hand.
