Both the Hewescraft 180 SR 2011 and the Hewescraft 180 SR ET 2011 are modified-V 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 - Hewescraft 180 SR 2011 at 18,0 ft versus Hewescraft 180 SR ET 2011 at 20,1 ft. Weight tells a clearer story for trailering families: the Hewescraft 180 SR ET 2011 tips the scales at 1 850 lbs - 450 lbs less than the Hewescraft 180 SR 2011 at 1 400 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 - 150 hp for the Hewescraft 180 SR 2011 and 150 hp for the Hewescraft 180 SR ET 2011. 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 - 34 gal and 34 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.
Bottom line: The Hewescraft 180 SR ET 2011 at 20,1 ft is the right call if deck space, comfort, and entertaining are top of your list. The Hewescraft 180 SR 2011 at 18,0 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.
