Lately there have been some threads at different forums about aluminum boat cracks. I am sure it has some aluminum owners agonizing about their boat and what they fish from.
I did a search here related to boat hull cracks out of curiosity. There are a LOT more problems with fiberglass hulls than there are with metal boats if you look. I know there are probably more glass boat owners, but the ratio of hull problems is significant. They have spider cracks, stress cracks, transom cracks, scratches, blisters, and through the hull cracks. And they have a lot of examples.
I have had several boats. I had a scratch in the gel of a glass boat that went into three different colors of gel with sparkle in each. It was bad. With a metal boat, you can match the paint and get an airgun and paint it.
I had fiberglass blisters on the hulls twice. They won't warranty that anymore. Why?
I got on a stump and scratched the living heck out of the bottom.
I was at the ramp the other day and there was a guy with a glass boat crawling all under it. He said he hit a stump and the bilge was pumping out water steadily and he had a hole in the hull.
Yes, you can have a problem with a metal boat. A human being welds and mistakes can happen. Some manufacturers give the first owner a lifetime warranty and are good about replacing it with a new hull. Try getting a new replacement glass boat. Try getting a warranty for fiberglass blisters past one year. The new aluminums are great as far as ride, control, design and functionality. They are 100 times better than what was available 5-10 years ago.
Like most people here, I could drive a glass boat if I wanted to. They definitely have their place, like big water. But if you are a new guy or even an old guy like me considering a metal boat, I think you will find most owners here would buy metal again. All boats are susceptible to problems, but if metal boat fits your style, do it. I would buy mine again and most would.
