The R-31 S shares many of the features and qualities of her smaller sisterships but some notable additions to this larger model make her ideal for extended cruising while still being a trailerable trawler. The builders at Ranger Tugs 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 foredeck seating, the R-31 boasts a larger cockpit area with wraparound seating utilizing seats that fold out of the gunwale. When not entertaining, seats are folded leaving the
cockpit unencumbered.

The interior layout of the R-31 S 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 helm station that maximize interior space. A starboard side door provides easy access from the helm to the side decks so crew can get to the bow for line handling.

Like all Ranger Tugs, the R-31 S 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 320 HP engine that achieves a 16 knot cruise speed.
