Crownline 206 LS 2005 vs Crownline 21 SS 2010 - Boat Spec Comparison

Q: Which is the larger boat - the Crownline 206 LS 2005 or the Crownline 21 SS 2010?

The Crownline 21 SS 2010 is the longer of the two at 20,8 feet overall. The Crownline 206 LS 2005 comes in at 19,0 feet, making it roughly 1,8 ft shorter - a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer - the Crownline 206 LS 2005 or the Crownline 21 SS 2010?

For trailering, the Crownline 206 LS 2005 has the edge at 3 500 lbs dry weight versus 3 700 lbs for the Crownline 21 SS 2010. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.

Q: Which boat can handle a bigger outboard?

The Crownline 21 SS 2010 is rated to a maximum of 320 hp, giving it the larger power ceiling. The Crownline 206 LS 2005 tops out at 270 hp. Keep in mind that maximum ratings are just that - matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.

Q: How many people can each boat hold?

The Crownline 206 LS 2005 is Coast Guard rated for 8 passengers, while the Crownline 21 SS 2010 is certified for 10. Note that legal capacity and comfortable capacity aren't always the same thing - on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.

Q: Do these boats require an oversize trailer permit to tow on US highways?

Both the Crownline 206 LS 2005 and Crownline 21 SS 2010 share an 102 in. (5.9 m) beam - meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.

Q: How do the fuel tanks compare on the Crownline 206 LS 2005 and Crownline 21 SS 2010?

Both boats carry similar fuel loads - 40 gallons and 41 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.

Q: Are the Crownline 206 LS 2005 and Crownline 21 SS 2010 from the same manufacturer?

Yes - both the Crownline 206 LS 2005 and the Crownline 21 SS 2010 are built by Crownline. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.

Detailed Evaluation & Buyer Recommendation

Crownline 206 LS 2005 vs Crownline 21 SS 2010: Same Brand, Different Boat

The Crownline 206 LS 2005 vs Crownline 21 SS 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 - Crownline 206 LS 2005 at 19,0 ft versus Crownline 21 SS 2010 at 20,8 ft. Weight tells a clearer story for trailering families: the Crownline 21 SS 2010 tips the scales at 3 700 lbs - 200 lbs less than the Crownline 206 LS 2005 at 3 500 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 320 hp, the Crownline 21 SS 2010 has a 50-hp advantage over the Crownline 206 LS 2005's 270-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 40 gal and 41 gal - so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Crownline 21 SS 2010 is rated for 10 passengers, while the Crownline 206 LS 2005 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crownline 21 SS 2010 could be the deciding factor.

Bottom line: Choose the Crownline 21 SS 2010 if your priority is putting more people on the water - it handles 10 passengers and at 20,8 ft it has the deck room to back that rating up comfortably. The Crownline 206 LS 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
