I agree with you. Brent doesn't much care how the boats look. If he did he would provide design drawings that enabled the builder to replicate his design ideas. Most of Brents boats could be greatly improved aesthetically with just better choice of paint schemes and colors.
But I see one boat in that group that is very good looking. In the second photo there is a pilot house boat off to the right, on the next dock. Now that is a good looking boat. And, they built 600 of them!
I know which one I would prefer to do the maintenance on, or be in on a dark, foggy, moonless night with Fukashima debris, or broken up log booms around, and it certainly wouldn't be the plastic one with all the dead vegetation bolted to it . It definitely wouldn't be the one with fragile, trip wire lifelines.
My boats rarely come up for sale. Owners tend to hang on to them. So for most people, simply buying one is a rare option, and the number of people who would build their own is much smaller than the number of people who would simply buy a boat. There is simply not a big enough market for mass produced, stock production steel boats . Never has been . It appears that market for mass produced stock plastic boats is rapidly declining as well.
As Bob mentioned in his earlier post, there is something attractive about the rugged beauty of a work boat. The more experience a cruiser has, the greater the attraction of a work boat look, and the less interest they have in the flimsy, dainty , fragile, boat show look. Mine are aimed at those who appreciate toughness and reliability , more than a good bondo job. my clients don't go to a lot of trouble to make their boats or gear look dainty and fragile, in a way that the naïve, production boat market demands.
