The Dehler 29 Shoal Draft 1997 vs Dehler 38SQ 2020 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 38SQ 2020 measures 39,7 feet overall (2020), giving it roughly 10,9 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 38SQ 2020 tips the scales at 16 534 lbs — 9 589 lbs less than the Dehler 29 Shoal Draft 1997 at 6 945 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.
The power gap is worth calling out. Rated to 39 hp, the Dehler 38SQ 2020 has a 27-hp advantage over the Dehler 29 Shoal Draft 1997's 12-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Dehler 38SQ 2020 carries 42 gallons versus 16 gallons in the Dehler 29 Shoal Draft 1997. 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 38SQ 2020 is rated for 12 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 38SQ 2020 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Dehler 38SQ 2020 displaces 16 534 lbs — a 9 589-lb difference over the Dehler 29 Shoal Draft 1997 at 6 945 lbs. That gap separates two entirely different categories of sailing: the heavier boat is built for offshore passage-making and load-carrying, while the lighter hull rewards performance sailing and easier handling in lighter air.
Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Dehler 38SQ 2020 draws 6,8 ft, compared to 4,0 ft for the Dehler 29 Shoal Draft 1997. That 2,8-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 auxiliary power the Dehler 38SQ 2020 carries a 39-hp engine against 12 hp on the Dehler 29 Shoal Draft 1997. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
For extended cruising, water capacity matters: the Dehler 38SQ 2020 carries 78 gallons versus 26 gallons on the Dehler 29 Shoal Draft 1997 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Dehler 38SQ 2020 is the offshore and bluewater choice — at 16 534 lbs displacement and 40 ft it has the load capacity, range, and seakeeping for extended passages. The Dehler 29 Shoal Draft 1997 at 6 945 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
