Overview
The B/One is an exciting, new 7m (23ft) trailer-able, one-design sport boat by Bavaria Yachtbau in Giebelstadt, Germany. Bavaria asked Farr Yacht Design for an economical one-design that would impress advanced sailors with excellent performance, yet be easy to handle and operate for the weekend sailor and his/her family. Farr Yacht Design, the designers of the B/One, have met these requirements with a technologically advanced hull shape developed from the Volvo Open 70 and Farr 400, an easy to use sailplan, and interior features you would expect to find on a boat 3 feet longer. The B/One has the power to weight ratio to perform well both upwind and downwind. The 34m2 (377ft2) of upwind sail area is set on an aluminum mast. The 48m2 (517ft2) asymmetrical spinnaker flies on a 1.3m (4.3ft) retractable bow sprit providing plenty of downwind horsepower. The keel and rudder are retractable making docking or anchoring in shallow water possible. The retractable keel also makes slip launching a breeze and allows for very low trailering heights, so that the boat can be towed by a relatively small vehicle. The B/One promises to be an absolute delight to sail and operate with unique features from bow to stern.

Hull and Deck
The hull shape clearly shows the influence, and is a direct descendant, of the Farr 400 and Volvo Open 70 in its full bow shape, broad and powerful stern sections and chined aft topsides. These features combine to provide exceptional speed, optimal balance and solid, dependable handling in all conditions. The maximum beam limit for trailering (2.5m) is seamlessly integrated into the hull and deck detailing to conceal fittings, provide a smooth, rounded deck edge and maximize crew weight stability.
Inspired by the sleek look of larger, modern high-performance one designs such as the Farr 400, the deck is flush with only a slightly raised cabin top to create the necessary headroom down below and contain the required sailing functions on deck. The cockpit is wide and open providing plenty of room for crew maneuvers during racing or seating for friends and family on a weekend harbor cruise. Sail handling is performed without winches or excessive hardware, but still providing all the necessary sail controls demanded by advanced one-design sailors, including adjustable jib tracks and a powerful boomvang. The large, round foredeck hatch provides ample light and ventilation to the interior, and serves as the opening for launching and retrieving the spinnaker via string takedown system. The waterproof companionway cover hinges completely forward providing a large opening to the interior. The cover can also be partially opened to cover the horizontal surface of the companionway while still providing ventilation to the interior via the open vertical surface.
