Aluminum boats have there place. There alright for the 1 day a week calm water trips, Give them the Great lakes test 5,6,7 days a week, 8, 10 hour days, then tell me if you don't have leaks. If I had to do it over again, I would go with Harborcraft or Stanley, cost more, but are life time boats. Just ask yourself if you see big cruiser boats in aluminum. Most charter boats that fish the great lakes are glass. I had the head guy from Princecraft look at my boat and he told me my problem was wave action. I was in a company in Bradford that repaired aluminum boats, he had every make there getting fixed. A buddy of mine only had his boat 2 years and the bow folded up from waves on Lake O. If it gets rough, trolling speed only back to port.
