The R-31 CB (Command Bridge) offers many notable features to make her ideal for extended cruising while still being a trailerable trawler. The R-31 was the first Ranger Tug to feature a flybridge equipped with electronic controls at both the upper and lower helm. The flybridge also retracts to allow for trailering the 31'. The builders at Ranger Tugs also equipped the foredeck with seating and a table that can be raised or lowered depending on whether the boat is under way or at anchor or dock for entertaining. In addition to the extra seating now available on the flybridge and foredeck the R-31 allows for a larger cockpit area with wraparound seating and extra seating that folds out of the gunwale. When not entertaining, seats are folded leaving the cockpit unencumbered.

The interior layout of the R-31 features two staterooms-one large island berth forward with en suite head and a midship berth and day head. Those who are familiar with Ranger Tugs models will recognize the galley layout and lower helm station that maximize interior space. A starboard side door provides easy access from the lower helm to the side decks so crew can get to the bow for line handling.

Like all Ranger Tugs, the R-31 comes essentially turnkey with standard features and equipment intended to make her owner's experience hassle-free and allow for ease of handling and comfort under way. Standard equipment includes bow and stern thrusters and a Volvo D4 300hp engine that achieves a 16 knot cruise speed.
