Sirius 35 DS Sailboat Review, Specs, and Listings

Design and Construction

The defining idea of the 35 DS is its split-level living arrangement, which the builder credits with creating the space of a 40-foot yacht in a 35-foot hull through an innovative split-level living arrangement. The hull and deck are hand-laid fiberglass, with vacuum-adhered sandwich construction above the waterline for stiffness and insulation, and parts of the deck are also built in sandwich. The hull-deck connection and bulkheads are laminated from all sides, and the keel—about 2.6 tonnes of cast iron, or optionally a hardened lead bulb—is glued and screwed to the hull with up to ten 20 mm stainless steel bolts through flat-rolled steel, its loads redistributed by massively laminated bottom floor sections. Writing in New Boat Preview, the reviewer noted that the hand-laid fiberglass reinforced with vacuum-adhered sandwich construction for stiffness and insulation marks the boat as built for offshore work, and the interior shows Sirius’s hallmark mahogany joinery. The boat carries CE Category A (Ocean) certification for worldwide travel.

Rig and Sail Plan

The 35 DS is rigged as a fractional sloop with a 2-spreader rig: forestay, shared backstay with cascade system, two upper, two middle, and two lower shrouds. The standard mainsail measures 33.5 m² and the self-tacking jib 23.2 m², while a Genoa I of 42 m² and Genoa II of 28 m² are listed, along with a 110 m² spinnaker, 86 m² furling gennaker, and 55 m² furling drifter. A performance rig with 23 percent more sail area is offered. The main boom carries two in-boom single-line reefing systems and a kicking strap, and mast and boom are aluminium. The self-tacking-jib system paired with the manageable standard sail plan makes short-handed sailing plausible, and the deep fin keel draws as much as 6 feet 10 inches while the lifting keel lifts to 2 feet 9 inches.

Accommodations

The raised salon gives true 360-degree views and abundant natural light, and by omitting a conventional aft cabin in favor of a sideways companionway and U-shaped seating, the whole low-level area is more spacious than on the Sirius 38 DS. Headroom is 1.95 m or more. Buyers could choose two, four, or six berths and one or two heads. In the two-berth version, the forecabin occupies all space forward of the main bulkhead, with a bed truly big for this size of boat and a cosy double sofa with extendable pull-out, plus a television and book shelf opposite. The four-berth layout places the owner’s cabin half under the seating area amidships, with a luxury double berth 2.04 m long and 1.60 m wide running the full width. The saloon table optionally converts to a 1.40 m by 2.20 m double berth. A standout feature is the dedicated workshop and storage area accessed by moving the saloon seat forward, which keeps tools and spares organized on a boat this size.

Engine and Systems

The standard power is a Volvo Penta D2-40, though the equipment list also cites a Volvo-Diesel D2 50 of 37.5 kW (51 hp) with a double cooling system, seawater filter, and saildrive with folding propeller. Diesel capacity starts at 150 liters with tank display and oil filter; water begins at 220 liters with display; and a waste water tank from 138 liters upward has overboard discharge and dockside emptying. The side-access engine walkway through the saloon seat makes routine service unusually convenient for the length.

The Verdict

The Sirius 35 DS is a thoughtfully engineered deck saloon that delivers outsized accommodation and genuine ocean credentials in a 35-foot footprint. Its split-level layout, all-round vision, and dedicated workshop are rare at this size, and the multiple keel options let an owner match draft to cruising grounds. The hand-laid and sandwich construction, fully laminated structure, and Category A rating underline the serious intent.
