When two boats share the same hull type — in this case both the Silverton 43 Sport Bridge 2011 and the Silverton 45 Convertible 2012 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 45 Convertible 2012 measures 47,7 feet overall (2012), giving it roughly 4,3 additional feet of deck space compared to the Silverton 43 Sport Bridge 2011 at 43,4 feet (2011). Weight tells a clearer story for trailering families: the Silverton 45 Convertible 2012 tips the scales at 42 048 lbs — 42 020 lbs less than the Silverton 43 Sport Bridge 2011 at 28 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.

For family outings this is probably the sharpest distinction between the two. The Silverton 45 Convertible 2012 is rated for 14 passengers, while the Silverton 43 Sport Bridge 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 45 Convertible 2012 could be the deciding factor.
