Trawlers are usually designed with a round chine, or hull configuration with a curve near the waterline instead of a hard chine typically found on semi-displacement motor yachts. Trawlers typically have deeper drafts (with a skeg or keel deeper than the propellers so that the running gear and propellers aren't damaged if the hull touches the bottom).

Trawlers with full-displacement hulls are for yachtsmen that place a high value on distance, comfort, and safety over speed. With a caring owner, many of these trawlers are still in use today. Classic trawlers and motor yachts were typically built out of wood. However, many large trawlers, and expedition yachts over 75', are built with steel and aluminum hulls and superstructures. Trawler Construction & Hull Design: Beginning in the 1970's, most trawlers are fiberglass-construction. Trawlers Characteristics: Trawlers are generally defined as motor yachts that boast fuel efficiency, rugged lines, sea worthy hull designs for long-distance cruising, and interior layouts that are beneficial for liveaboard yacht owners.
