Sunwind 31 Buyer's Guide
The Sunwind 31 is a Tord Sundén-designed fractional sloop with a solid fiberglass hull and a sandwich deck. For a buyer in the brokerage market, she presents as a heavy-displacement coastal cruiser whose 18-horsepower Volvo Penta diesel and 39-percent ballast ratio define a steady, undramatic ownership profile.
Layouts on the Used Market
The Sunwind 31 carries a teak interior consistent with period Scandinavian production boats, and a 26-gallon water tank that sets a realistic coastal range. Buyers should expect the standard aft-cockpit cruiser arrangement with the original joinery largely intact or refinished.
Equipment and Common Upgrades
Boats on the market commonly carry cabin heating, an autopilot, and a chartplotter as factory-era or early-owner fittings. For a buyer, heating extends shoulder-season use in northern waters, the autopilot reduces helm fatigue on long reaches, and the chartplotter modernizes navigation without altering the boat's character. No other equipment tiers are noted, so assume anything beyond these three is an individual owner's addition.
What to Inspect
The iron keel is the first corrosion suspect: examine the keel-to-hull joint and bilge for rust staining, pitting, or powdery deposits that signal galvanic or stray-current attack. The sandwich deck should be tapped and probed around all penetrations — chainplates, winches, stanchions, and deck hardware — for soft spots or delamination that betray failed sealing over the years. Confirm the Volvo Penta 18-horsepower diesel starts cleanly and shows no coolant or exhaust leaks, as a mid-life or beyond unit defines the replacement envelope.
Availability and Buyer's Takeaway
These boats are typically found in Denmark and the Netherlands. Before committing, walk through this short list:
- Inspect iron keel for corrosion at the hull joint
- Tap sandwich deck around all fasteners for delamination
- Verify diesel starts without smoke or leaks
- Confirm heating, autopilot, and chartplotter function
- Check teak interior for structural soundness, not just finish
