I run a Lund 1875 Crossover with a 150 and 9.9 kicker. I feel 100% comfortable in anything less than 3 footers. As the wind picks up above that it’s not that I don’t feel safe but your ability to run around is limited due to taking a beating in the lighter aluminum boat. As the waves pick up you will have to learn to ride the waves. I still love my boat and when it get that bad I don’t want my family out there anyway.
