Baycoastal,

I'm awaiting delivery on a 170 with a 60 yammi (should be ready this week) and 90% of the time I'll be fishing alone or with one other person but occasionally I'll use it for tubing/skiing and I still wonder if I should have gotten the 190 with a 115. The main reasons I ended up going with the 170 was I felt it would be a whole lot easier launching it by myself as opposed to launching the 190 and the amount of fuel the 190 burns (approximately 10 gallons per hour at cruising speed vs. approximately 4 ghp at cruising speed for the 170).

You didn't say how old the kids are but they will grow if they aren't big already. For the difference in the price I would lean toward the 190 but regardless of which boat you end up purchasing get the swim platfrom.

Regardless of which boat you end up getting, enjoy it and the time spent on it with family and friends because it passes too quickly.
