The Southern Wind SW105 Power of Two 2019 vs Southern Wind SW110 Thalima 2010 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.
On paper these two are close siblings in the size department — Southern Wind SW105 Power of Two 2019 at 113,4 ft versus Southern Wind SW110 Thalima 2010 at 112,0 ft. Weight tells a clearer story for trailering families: the Southern Wind SW110 Thalima 2010 tips the scales at 189 597 lbs — 36 376 lbs less than the Southern Wind SW105 Power of Two 2019 at 153 221 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 405 hp, the Southern Wind SW110 Thalima 2010 has a 100-hp advantage over the Southern Wind SW105 Power of Two 2019's 305-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 34 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Displacement is where these two sailboats genuinely part ways. The Southern Wind SW110 Thalima 2010 displaces 189 597 lbs — a 36 376-lb difference over the Southern Wind SW105 Power of Two 2019 at 153 221 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 Southern Wind SW105 Power of Two 2019 draws 16,4 ft, compared to 13,8 ft for the Southern Wind SW110 Thalima 2010. That 2,6-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.
For auxiliary power the Southern Wind SW110 Thalima 2010 carries a 405-hp engine against 305 hp on the Southern Wind SW105 Power of Two 2019. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
Bottom line: The Southern Wind SW110 Thalima 2010 is the offshore and bluewater choice — at 189 597 lbs displacement and 112 ft it has the load capacity, range, and seakeeping for extended passages. The Southern Wind SW105 Power of Two 2019 at 153 221 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
