The spec sheets list the Extreme 1770 Enduro 2027 as open aluminium centre-console and the Extreme 545 Side Console 2027 as side-console, so check how each hull rides in the conditions you use before you decide.

On paper these two are close siblings in the size department - Extreme 1770 Enduro 2027 at 18,1 ft versus Extreme 545 Side Console 2027 at 18,2 ft. Weight tells a clearer story for trailering families: the Extreme 1770 Enduro 2027 tips the scales at 2 205 lbs - 111 lbs more than the Extreme 545 Side Console 2027 at 2 094 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 - 70 hp for the Extreme 1770 Enduro 2027 and 70 hp for the Extreme 545 Side Console 2027. 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. Fuel capacity breaks the other way: the Extreme 545 Side Console 2027 carries 26 gallons versus 21 gallons in the Extreme 1770 Enduro 2027. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 4 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.
