Both the Formosa Marine GRT 455 Side Console 2027 and the Formosa Marine SRT 635 X Bowrider 2027 are V-hull designs, both built in aluminium, 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 Formosa Marine SRT 635 X Bowrider 2027 measures 21,1 feet overall (2027), giving it roughly 5,0 additional feet of deck space compared to the Formosa Marine GRT 455 Side Console 2027 at 16,1 feet (2027). Weight tells a clearer story for trailering families: the Formosa Marine SRT 635 X Bowrider 2027 tips the scales at 2 279 lbs - 1 408 lbs less than the Formosa Marine GRT 455 Side Console 2027 at 871 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 power gap is worth calling out. Rated to 225 hp, the Formosa Marine SRT 635 X Bowrider 2027 has a 135-hp advantage over the Formosa Marine GRT 455 Side Console 2027's 90-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Formosa Marine SRT 635 X Bowrider 2027 carries 58 gallons versus 17 gallons in the Formosa Marine GRT 455 Side Console 2027. 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 Formosa Marine SRT 635 X Bowrider 2027 is rated for 8 passengers, while the Formosa Marine GRT 455 Side Console 2027 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Formosa Marine SRT 635 X Bowrider 2027 could be the deciding factor.
