Every boat is beautiful to its owner, you won’t find anyone who will admit that their boat is a dog, but what is beautiful to one eye is not to another.
If you’re designing for yourself this little problem isn’t a problem, but if you’re designing for someone else, then it can be.
Phil Bolger designed some very square boats, I happen to think that they are beautiful because they meet the design purpose. Similarly, Jim Michalak designs squareish boats and I like the look of them too. Other people don’t.
