Hanseat 70 Buyer's Guide
Shopping the used market for a Hanseat 70 means looking at a 34-foot fiberglass masthead sloop designed by Willy Asmus and built by Asmus KG Yachtbau from 1971 onward, part of a 70 series that saw more than 200 examples constructed and developed between 1970 and 1981. These are solid cruisers with a documented record of ocean voyages, and the base model is recognisable by its wooden foot rail among the 70, 70B, 70 MKIII and 70 BII variants.
Layouts on the Used Market
The Hanseat 70 carries a fin keel with spade rudder and a moderate-displacement hull of 12,125 pounds, giving 6.23 feet of headroom below and 66 gallons of water capacity against 32 gallons of diesel. The cockpit is arranged with the helmsman seated slightly above the crew and separated by a wide traveller rail, a layout carried from the early superstructure models. Buyers will find the 70B and later MKIII or BII versions differ mainly in skeg configuration, where the earliest boats used a particularly solid iron skeg that later disappeared entirely.
Equipment and Common Upgrades
Most boats on the brokerage market will already carry a chartplotter, autopilot and cabin heating as commonly fitted equipment, while AIS is often seen. Less common but possible owner additions include an inverter, self-tacking jib, furling main, teak decks or a life raft. For a buyer, the meaningful clusters are navigation and self-steering — chartplotter and autopilot with AIS reduce watch burden — and comfort systems such as heating for Baltic-season use.
What to Inspect
The hull construction used roving fabric with hand-rolled, compacted and annealed laminate, which owners describe as very strong, and the round-the-world Gegenwind survived a reef collision with ten centimetres of keel lost and no leak. Inspect the keel heel and hull for prior grounding damage, and confirm which skeg type is present, since the early solid-iron skeg was deleted on later models. The German Navy's 70Bs remain in good condition after nearly 40 years of training use, a useful sign of structural endurance in well-maintained examples.
Availability and Buyer's Takeaway
Typical markets for the Hanseat 70 are Germany, Denmark and the Netherlands. For a buyer, the checklist is short: confirm the specific 70-series variant and skeg presence, check keel and hull for grounding history, verify the heating and navigation suite are operational, and prefer a documented maintenance record given the boat's age. These are steady, well-built cruisers with real offshore pedigree.
