Both the Crownline 300 LS 2009 and the Crownline E1 EC 2013 are deep-V designs, both built in fibreglass, 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 Crownline 300 LS 2009 measures 30,0 feet overall (2009), giving it roughly 9,5 additional feet of deck space compared to the Crownline E1 EC 2013 at 20,5 feet (2013). Weight tells a clearer story for trailering families: the Crownline 300 LS 2009 tips the scales at 8 900 lbs - 4 500 lbs more than the Crownline E1 EC 2013 at 4 400 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.
The power gap is worth calling out. Rated to 600 hp, the Crownline 300 LS 2009 has a 300-hp advantage over the Crownline E1 EC 2013's 300-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Crownline 300 LS 2009 carries 84 gallons versus 37 gallons in the Crownline E1 EC 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 9 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 Crownline 300 LS 2009 at 30,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Crownline E1 EC 2013 at 20,5 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.
