Design and Construction
The DB-1's hull is fiberglass, with a solid layup rather than a cored skin, and the keel is lead anchor. Dehler built the boat during its classic production era using a monocoque hull-to-deck joint where deck and hull were laminated together inside the mold. The numbers tell the story of a boat tuned for both stiffness and volume: a length-to-beam ratio of 2.97 pairs an 11.2-foot beam against the 33.1-foot length, and that beam translated into unusual interior room. Period comparisons placed her as more spacious than 73% of similar designs anchor, while a 41% ballast ratio—higher than half of comparable sailboats anchor—and 3,525 pounds of lead give her a ballast-displacement figure near 48. A wetted surface of about 344 square feet and an immersion rate near 1,033 pounds per inch describe a hull that settles predictably under load.
Rig and Handling
The fractional sloop rig carries running rigging of defined lengths rather than only sail dimensions. Recommended sheet lengths run to 10.1 meters for both jib and genoa at 12 mm diameter, a 25.3-meter mainsheet of the same diameter, and a 22.2-meter spinnaker sheet anchor. Those figures imply a masthead-reachable deck plan built around manageable, repeatable leads. With a theoretical hull speed of 6.9 knots anchor and a draft that varies from about 6.2 to 6.5 feet depending on load anchor, the DB-1 sits at the deep end of her size class—a characteristic that limits her to major marinas but pays back in directional stability and righting moment.
Accommodations
The DB-1's standout accommodation virtue is volume where it counts. The same beamy proportions that produced a 2.97 length-to-beam ratio also produced a cabin with room ahead of most peers of the era. For a 33-footer of 1980, that relative roominess is the defining liveaboard and weekender asset, and it is what separates her from narrower racer-derived contemporaries.
The Verdict
The DB-1 is a van de Stadt–penned performance cruiser that traded the spartan interior of many 3/4-tonners for genuine volume, without giving up a high ballast ratio and a sea-kindly deep fin. She is a product of Dehler's classic molded-construction era.
Pros
- More interior space than 73% of comparable designs
- High 41% ballast ratio, exceeding half of similar boats
- Lead fin keel with deep, load-dependent draft for stability
- Continuous fiberglass hull-to-deck bond from molded construction
Cons
- Draft of 6.2–6.5 feet restricts her to major marinas
