Crownline 21 SS 2011 vs Crownline 21 SS 2012 — A Close Look at Two Modified Vees

When two boats share the same hull type — in this case both the Crownline 21 SS 2011 and the Crownline 21 SS 2012 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Crownline 21 SS 2011 at 20,8 ft versus Crownline 21 SS 2012 at 20,8 ft. At 37 lbs and 37 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 320 hp for the Crownline 21 SS 2011 and 320 hp for the Crownline 21 SS 2012. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 41 gal and 41 gal — so range won't be a tiebreaker here.

Both boats are rated for 1 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.

Bottom line: The Crownline 21 SS 2011 and Crownline 21 SS 2012 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Crownline 21 SS 2011 vs Crownline 21 SS 2012 — Common Questions

Which is the larger boat — the Crownline 21 SS 2011 or the Crownline 21 SS 2012?
The Crownline 21 SS 2012 is the longer of the two at 20,8 feet overall. The Crownline 21 SS 2011 comes in at 20,8 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crownline 21 SS 2011 or the Crownline 21 SS 2012?
For trailering, the Crownline 21 SS 2012 has the edge at 37 lbs dry weight versus 37 lbs for the Crownline 21 SS 2011. 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.
How many people can each boat hold?
The Crownline 21 SS 2011 is Coast Guard rated for 1 passengers, while the Crownline 21 SS 2012 is certified for 1. 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Crownline 21 SS 2011 and Crownline 21 SS 2012 share an 102 in. (2.59 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.
How do the fuel tanks compare on the Crownline 21 SS 2011 and Crownline 21 SS 2012?
Both boats carry similar fuel loads — 41 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.
Are the Crownline 21 SS 2011 and Crownline 21 SS 2012 from the same manufacturer?
Yes — both the Crownline 21 SS 2011 and the Crownline 21 SS 2012 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.
