Matching a modified vee Sylvan Alaskan 12 TLS 2009 against a flat Sylvan Jon 1436 2011 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Sylvan Alaskan 12 TLS 2009 at 11,0 ft versus Sylvan Jon 1436 2011 at 14,0 ft. At 185 lbs and 185 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling — 15 hp for the Sylvan Alaskan 12 TLS 2009 and 20 hp for the Sylvan Jon 1436 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 boats are rated for 3 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.
At this size, power-to-weight ratio matters more than outright horsepower. The Sylvan Jon 1436 2011 comes in at 9 lbs per hp versus 12 lbs per hp for the Sylvan Alaskan 12 TLS 2009. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: The Sylvan Jon 1436 2011 at 14,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sylvan Alaskan 12 TLS 2009 at 11,0 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.
