Bootswerft Dyas Buyer's Guide
Shopping the used market for a Bootswerft Dyas means understanding that you are looking at a late-sixties German keel racer built by Mader GmbH, Leonhard, Bootswerft to Helmut Stöberl's lines — a round-bilge fibreglass boat of about 23.5 feet, slim and light, meant for two people and a trapeze rather than a family cruise. Around two thousand have been built, so the class is not rare, but every example is fundamentally a racing keelboat, and the right buyer is someone who wants a quick, overdriven planing dinghy-keeler, not a pocket cruiser.
Layouts on the Used Market
Because the Dyas was designed as a two-man regatta boat with Star-boat-scale dimensions, there is no cruising-layout variation to choose between. The hull is a solid fibreglass round-bilge form on a fin keel with bulb, and the cockpit and deck were laid out around a trapeze and spinnaker rather than sleeping or galley space. Any boat presented as a Dyas will share that racing footprint; differences between examples will be in rig tune, sail inventory, and trailer condition rather than in interior plan.
Equipment and Common Upgrades
The original specification included a spinnaker and trapeze with sails from North Sails Wagner, and the fractional rig was developed by that firm. For a buyer, the meaningful equipment questions are the rig and sail-handling side: a full spinnaker kit with its 51.8-foot sheets and a trapeze rig are the consequential items, since they define the boat's regatta readiness. Beyond that, the overdriven rig — more sail area than 100 percent of similar boats — means mast, halyards, and sheets take real loads, so a clean fractional sloop with intact running rigging matters more than creature comforts that were never part of the design.
What to Inspect
The Dyas's documented profile is built on design and performance figures, so a used-boat inspection leans on what the numbers imply for wear. The boat is significantly overrigged for its size, with a sail-area-to-displacement ratio that leaves it faster than 96 percent of similar designs in light wind, which concentrates load in mast, chainplates, and the 8 mm halyards and 10 mm sheets listed for the class. The capsize screening value of 2.32 means it would not be accepted to participate in ocean races, so evidence of offshore misuse or structural strain at the fin-bulb keel root deserves a close look. Otherwise, standard fibreglass hull-and-deck checks apply, with attention to the round-bilge topsides and the 150 square feet of wetted surface for osmotic or impact damage.
Availability and Buyer's Takeaway
No regional market detail is provided for the Dyas, so availability must be judged from general brokerage channels rather than a named stronghold. For the shopper, the takeaway is a short discipline:
- Confirm the boat is a true two-person racer, not misrepresented as a cruiser
- Verify the fractional rig, spinnaker, and trapeze are complete and from North Sails Wagner or equivalent
- Check keel-bulb attachment and round-bilge hull for stress from the overrigged, light-displacement platform
- Expect no accommodation and no cruising tankage; budget for racing sail inventory, not comfort gear
