Both the Silverton 33 Convertible 2011 and the Silverton 39 Motor Yacht 2008 are semi-displacement designs, both built in fibreglass, so 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?

Size is the most obvious dividing line here. The Silverton 39 Motor Yacht 2008 measures 43,0 feet overall (2008), giving it roughly 10,4 additional feet of deck space compared to the Silverton 33 Convertible 2011 at 32,6 feet (2011). Weight tells a clearer story for trailering families: the Silverton 39 Motor Yacht 2008 tips the scales at 24 900 lbs - 8 100 lbs less than the Silverton 33 Convertible 2011 at 16 800 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 Silverton 39 Motor Yacht 2008 tops out at 440 hp. Engine specs for the Silverton 33 Convertible 2011 aren't listed - confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Silverton 39 Motor Yacht 2008 carries 334 gallons versus 208 gallons in the Silverton 33 Convertible 2011. 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 Silverton 39 Motor Yacht 2008 is rated for 13 passengers, while the Silverton 33 Convertible 2011 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Silverton 39 Motor Yacht 2008 could be the deciding factor.
