Silverton 33 Convertible 2007 vs Silverton 33 Sport Coupe 2009 — Same Brand, Different Boat

The Silverton 33 Convertible 2007 vs Silverton 33 Sport Coupe 2009 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 — Silverton 33 Convertible 2007 at 32,0 ft versus Silverton 33 Sport Coupe 2009 at 32,0 ft. At 168 lbs and 163 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.

The power gap is worth calling out. Rated to 375 hp, the Silverton 33 Convertible 2007 has a 100-hp advantage over the Silverton 33 Sport Coupe 2009's 275-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 208 gal and 208 gal — so range won't be a tiebreaker here.

Both boats are rated for 9 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: Performance buyers should lean toward the Silverton 33 Convertible 2007 and its 375-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Silverton 33 Sport Coupe 2009 with its 275-hp rating is the more economical daily driver.

Silverton 33 Convertible 2007 vs Silverton 33 Sport Coupe 2009 — Common Questions

Which is the larger boat — the Silverton 33 Convertible 2007 or the Silverton 33 Sport Coupe 2009?
The Silverton 33 Sport Coupe 2009 is the longer of the two at 32,0 feet overall. The Silverton 33 Convertible 2007 comes in at 32,0 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 Silverton 33 Convertible 2007 or the Silverton 33 Sport Coupe 2009?
For trailering, the Silverton 33 Sport Coupe 2009 has the edge at 163 lbs dry weight versus 168 lbs for the Silverton 33 Convertible 2007. 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.
Which boat can handle a bigger outboard?
The Silverton 33 Convertible 2007 is rated to a maximum of 375 hp, giving it the larger power ceiling. The Silverton 33 Sport Coupe 2009 tops out at 275 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.
How many people can each boat hold?
The Silverton 33 Convertible 2007 is Coast Guard rated for 9 passengers, while the Silverton 33 Sport Coupe 2009 is certified for 9. 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 Silverton 33 Convertible 2007 and Silverton 33 Sport Coupe 2009 share an 12 ft. 8 in. (3.86 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 Silverton 33 Convertible 2007 and Silverton 33 Sport Coupe 2009?
Both boats carry similar fuel loads — 208 gallons and 208 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Silverton 33 Convertible 2007 and Silverton 33 Sport Coupe 2009 from the same manufacturer?
Yes — both the Silverton 33 Convertible 2007 and the Silverton 33 Sport Coupe 2009 are built by Silverton. 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.
