Well, design is subjective just like music. What I think sucks someone else may think is great. I think wannabe windows are the very definition of ugly but i can fully appreciate their function on vessels that require that function. Toy boats don't need the function, therefore they are simply ugly in my opinion. I would never buy a Selene, for example, because i have no interest in running what to me is an very ugly boat.
The people who buy Selenes obviously feel differently.
Grand Banks are okay in my opinion but there are far better looking designs. Most production boats, particularly those from the past twenty years or so I find pretty ugly. I understand the reason why, as interior space takes precedence over exterior aesthetics, at least my definition of exterior aesthetics.
A few production boats I find very good looking. Eastbays, for example, the ones without flying bridges. Nordic Tugs and Victory Tugs are very nice, again the ones without flying bridges in the case of the Nordic Tugs. The pilothouse de Fever design used on American Marine Alaskans, Flemings, and boats like the de Fever 46 are the best looking production boats around in my opinion.
But when it comes to the aesthetics of design, be it cars, boats or shoes, there's no wrong or right, there's just different. Someone may feel that a design element is very "wrong," but that opinion is only valid for that person. Others may agree, others may not, but it doesn't really matter to that one individual. What he or she thinks is what he or she thinks.
