Both the Formosa Marine SRT 635 Centre Cabin 2027 and the Formosa Marine SRT 635 Enclosed Centre Cabin 2026 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?

On paper these two are close siblings in the size department - Formosa Marine SRT 635 Centre Cabin 2027 at 21,1 ft versus Formosa Marine SRT 635 Enclosed Centre Cabin 2026 at 21,1 ft. Weight tells a clearer story for trailering families: the Formosa Marine SRT 635 Enclosed Centre Cabin 2026 tips the scales at 2 487 lbs - 159 lbs less than the Formosa Marine SRT 635 Centre Cabin 2027 at 2 328 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.

Both boats share a closely matched power ceiling - 225 hp for the Formosa Marine SRT 635 Centre Cabin 2027 and 225 hp for the Formosa Marine SRT 635 Enclosed Centre Cabin 2026. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads - 58 gal and 58 gal - so range won't be a tiebreaker here.

Both boats are rated for 7 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.
