The Southern Wind SW102 Egiwave 2015 vs Southern Wind SW120 2021 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 Southern Wind SW120 2021 measures 120,0 feet overall (2021), giving it roughly 15,8 additional feet of deck space compared to the Southern Wind SW102 Egiwave 2015 at 104,2 feet (2015). Weight tells a clearer story for trailering families: the Southern Wind SW120 2021 tips the scales at 189 000 lbs — 47 706 lbs less than the Southern Wind SW102 Egiwave 2015 at 141 294 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 493 hp, the Southern Wind SW120 2021 has a 188-hp advantage over the Southern Wind SW102 Egiwave 2015's 305-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Southern Wind SW120 2021 is rated for 36 passengers, while the Southern Wind SW102 Egiwave 2015 caps at 31. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Southern Wind SW120 2021 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Southern Wind SW120 2021 displaces 189 000 lbs — a 47 706-lb difference over the Southern Wind SW102 Egiwave 2015 at 141 294 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.
Both boats draw a similar depth — 13,1 ft and 12,4 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
For auxiliary power the Southern Wind SW120 2021 carries a 493-hp engine against 305 hp on the Southern Wind SW102 Egiwave 2015. 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 SW120 2021 is the offshore and bluewater choice — at 189 000 lbs displacement and 120 ft it has the load capacity, range, and seakeeping for extended passages. The Southern Wind SW102 Egiwave 2015 at 141 294 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
