When two boats share the same hull type — in this case both the Silverton 42 Convertible 2011 and the Silverton 45T-Series 2011 are semi displacement 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?

Size is the most obvious dividing line here. The Silverton 45T-Series 2011 measures 47,7 feet overall (2011), giving it roughly 3,2 additional feet of deck space compared to the Silverton 42 Convertible 2011 at 44,5 feet (2011). Weight tells a clearer story for trailering families: the Silverton 45T-Series 2011 tips the scales at 42 048 lbs — 41 785 lbs less than the Silverton 42 Convertible 2011 at 263 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 45T-Series 2011 tops out at 720 hp. Engine specs for the Silverton 42 Convertible 2011 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Silverton 45T-Series 2011 carries 607 gallons versus 542 gallons in the Silverton 42 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 45T-Series 2011 is rated for 14 passengers, while the Silverton 42 Convertible 2011 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Silverton 45T-Series 2011 could be the deciding factor.
