Boat shows are great places to board a large variety of boats rather quickly. Trawlerfest in Washington is a good one but any boat show would not be a waste of time in my opinion. Bottom line, these are heavy cabin cruisers, trawler is a marketing term used to conjure images of heavy fishing boats.
Regardless of verbiage, spend the next couple years attending any show you can. Get aboard any boat you can(sailboats too)and make notes of what you like and dislike. Include make and model in your notes as it will help later.
Yachtworld is a good place to kill time looking, just don't fall in love because pictures lie and transporting these boats long distances ain't cheap. If the price is too good to be true, there's typically a good reason for it.
