International 806 Buyer's Guide
The International 806 is a Pelle Petterson-designed 26-foot fractional sloop built by International Marine from 1974, with 510 examples recorded. On the used market she presents as a racer-cruiser with a hand-laid fibreglass hull, a 1.40-metre cast-iron fin keel, and a free-standing skeg-hung rudder — a small yacht whose sporting brief still leaves room for weekend comfort.
Layouts on the Used Market
Every 806 shares the same core arrangement: saloon and forecastle berths moulded as GRP sections into the hull, quarter-berths with plywood ends, and aft locker seats. The cabin uses matt-lacquered wood bent-boards in the cabinets and marine plywood with topcoat at the berth ends. A standard reinforced outboard mount accepts a motor up to 6 HP, so most used International 806s will show a portable auxiliary rather than an inboard installation.
Equipment and Common Upgrades
Used International 806s commonly show chartplotters, spinnakers, teak decks, and autopilots already fitted, with inverters a frequent addition. A layer of owner upgrades appears less often — solar, lithium batteries, heating, furling mains, and AIS fall in this group. For a buyer, the meaningful clusters are navigation (chartplotter and sometimes AIS), sail handling and downwind speed (spinnaker commonly, gennaker or asymmetric spinnaker as upgrades), and power independence (inverter often, solar and lithium less so). Teak decks are a cosmetic-period feature worth inspecting for adhesion rather than a systems concern.
What to Inspect
The keel is bolted by four 20 mm stainless bolts to two steel U-profile carriers laminated into the hull, with two further U-profile iron bars laminated in for suspension keel suspension. Check the keel-to-hull interface for any staining or bolt corrosion, since these carriers are structural and embedded. The rudder post is a 25 mm stainless shaft on a small skeg laminated to the post; confirm the skeg bond and shaft condition. Because the hull is solid hand-laid laminate without core, survey the topsides for the standard dark-blue stripes' condition and any stress cracking around the moulded berth sections, which are integral to hull rigidity.
Availability and Buyer's Takeaway
The 806 turns up most often in Germany, Denmark, Switzerland, Poland, and Sweden. For a shopper, the short list is: verify keel-bolt and U-carrier integrity, check the rudder skeg bond and stainless post, confirm the outboard mount and hull laminate, and assess any teak decks or added electrical kit for age. A sound example rewards the buyer with a precise, roomy Petterson cruiser-racer.
