The Princecraft 20 ST 2006 vs Princecraft Platinum SE 198 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 Princecraft Platinum SE 198 2010 measures 19,4 feet overall (2010), giving it roughly 17,4 additional feet of deck space compared to the Princecraft 20 ST 2006 at 2,0 feet (2006). Weight tells a clearer story for trailering families: the Princecraft 20 ST 2006 tips the scales at 1 775 lbs — 209 lbs more than the Princecraft Platinum SE 198 2010 at 1 566 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 200 hp, the Princecraft Platinum SE 198 2010 has a 110-hp advantage over the Princecraft 20 ST 2006's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Princecraft 20 ST 2006 carries 33 gallons versus 6 gallons in the Princecraft Platinum SE 198 2010. 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 Princecraft 20 ST 2006 is rated for 11 passengers, while the Princecraft Platinum SE 198 2010 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft 20 ST 2006 could be the deciding factor.
