I don't think it has to be completely ugly without the "house".. Here is an inspiration I found today..

The day I took off the windshield off my 1959 17' Lyman was the best boat ride I had with that boat.. Incidentally it never went back on.. Another thing I'm looking for is the ability to grab the dock when solo boating.. With the house you would have to run around or have an assistant..
