I did a brief search of these forums and did not find wide selection of ideas and vessels built as trawlers in a catamaran fashion...... So somewhat regrettably I need to make this link to a trawler forum that presents quite a variety of those types,.. https://www.trawlerforum.com/threads/powercat-trawlers.11299/ Perhaps some readers will find a particular one of interest, and bring a posting and discussion over here. The very first one in the discussions, the 62 foot Humminbyrd, was owned by a good friend of mine. I would have loved to have afforded to buy her when he decided to sell her.
