Designed by Bruce Johnson and the Brooklin Boat Yard design office, SONNY III is a 91-foot custom cold-molded sloop built for a repeat customer. She’s a larger replacement for the owner’s current 70-foot yacht, also built by Brooklin Boat Yard. SONNY III is a high-performance cruising yacht designed for daysailing and blue-water passages. Construction on SONNY III took 18 months.

The owner is a retired senior with limited mobility who requested a yacht with more accessibility. SONNY III provides numerous solutions to the owner’s mobility concerns, including chair lifts at each companionway, a power reclining chair in the master cabin, a side-boarding ladder and a transom-boarding platform.

SONNY III has classic styling, including a completely flush deck. The yacht has an aggressively raked bow and reverse transom, a teak deck and a varnished teak toe rail. Her twin cockpit configuration keeps guests safe in the center cockpit while all sail handling is in the aft working cockpit. Low, varnished-teak cockpit coamings and canvas dodgers protect each companionway opening.

SONNY III has a double headsail rig operated by hydraulic furlers that were built by Harken. The non-overlapping headsail configuration with chainplates pushed outboard greatly reduces loads and allows for a smaller mast section, winches and hardware. The mainsail has hydraulic in-boom furling. The carbon mast is from Offshore Spars with 3Di sails by North Sails.

The interior layout includes a crew cabin forward with private head and stall shower, two guest staterooms forward of the mast, one with ensuite head and stall shower and the other with a day head, also with separate shower. The main salon has an elliptical dining area, a pair of reclining chairs and a navigation station. Access to the full beam master stateroom is either through the portside passageway or through the generous galley to starboard. The master stateroom features an ensuite head with stall shower. The interior is finished in Herreshoff style with white and cream paintwork offset by American cherry joinery, leather upholstery and a teak and maple cabin sole.

SONNY III’s cold-molded, laminated-wood hull used WEST SYSTEM epoxy resin and vacuum bagging. The hull and deck have carbon reinforcements in specific high load areas. The ballast keel is a steel foil with integral tanks and with a lead bulb. The rudder is a carbon spade design.
