The Dehler 29 Shoal Draft 1997 vs Dehler 30 One Design One design 2019 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Dehler 30 One Design One design 2019 measures 33,1 feet overall (2019), giving it roughly 4,3 additional feet of deck space compared to the Dehler 29 Shoal Draft 1997 at 28,8 feet (1997). Weight tells a clearer story for trailering families: the Dehler 29 Shoal Draft 1997 tips the scales at 6 945 lbs — 772 lbs more than the Dehler 30 One Design One design 2019 at 6 173 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
Both boats share a closely matched power ceiling — 12 hp for the Dehler 29 Shoal Draft 1997 and 10 hp for the Dehler 30 One Design One design 2019. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Dehler 29 Shoal Draft 1997 carries 16 gallons versus 7 gallons in the Dehler 30 One Design One design 2019. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Dehler 30 One Design One design 2019 is rated for 10 passengers, while the Dehler 29 Shoal Draft 1997 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Dehler 30 One Design One design 2019 could be the deciding factor.
Both boats sit in a similar displacement bracket — 6 945 lbs for the Dehler 29 Shoal Draft 1997 and 6 173 lbs for the Dehler 30 One Design One design 2019. Comparable displacement means broadly similar seakeeping behaviour and load capacity, though hull form and ballast ratio will still produce noticeably different sailing characteristics.
Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Dehler 30 One Design One design 2019 draws 7,2 ft, compared to 4,0 ft for the Dehler 29 Shoal Draft 1997. That 3,2-foot difference affects which anchorages you can access, which haul-out facilities will take you, and how carefully you need to read the tide tables in shallower cruising grounds.
The Dehler 29 Shoal Draft 1997 uses Sloop rigging.
For extended cruising, water capacity matters: the Dehler 29 Shoal Draft 1997 carries 26 gallons versus 11 gallons on the Dehler 30 One Design One design 2019 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Dehler 30 One Design One design 2019 at 33,1 ft offers more living space, greater range, and a more substantial offshore capability. The Dehler 29 Shoal Draft 1997 at 28,8 ft is the easier, lower-cost option — simpler to crew and a strong choice for coastal and day sailing.
