The Southern Wind SW100 X Allseas 2023 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.

Size is the most obvious dividing line here. The Southern Wind SW110 Thalima 2010 measures 112,0 feet overall (2010), giving it roughly 12,0 additional feet of deck space compared to the Southern Wind SW100 X Allseas 2023 at 100,0 feet (2023). Weight tells a clearer story for trailering families: the Southern Wind SW110 Thalima 2010 tips the scales at 189 597 lbs — 53 997 lbs less than the Southern Wind SW100 X Allseas 2023 at 135 600 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 SW100 X Allseas 2023'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 SW110 Thalima 2010 is rated for 34 passengers, while the Southern Wind SW100 X Allseas 2023 caps at 30. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Southern Wind SW110 Thalima 2010 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Southern Wind SW110 Thalima 2010 displaces 189 597 lbs — a 53 997-lb difference over the Southern Wind SW100 X Allseas 2023 at 135 600 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 13,8 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

For auxiliary power the Southern Wind SW110 Thalima 2010 carries a 405-hp engine against 305 hp on the Southern Wind SW100 X Allseas 2023. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
