Avalon 18 ft. GS 2013 vs Avalon Windjammer - 18 Foot 2007: Same Brand, Different Boat

The Avalon 18 ft. GS 2013 vs Avalon Windjammer - 18 Foot 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department - Avalon 18 ft. GS 2013 at 16,0 ft versus Avalon Windjammer - 18 Foot 2007 at 18,0 ft. Weight tells a clearer story for trailering families: the Avalon 18 ft. GS 2013 tips the scales at 1 600 lbs - 109 lbs more than the Avalon Windjammer - 18 Foot 2007 at 1 491 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 - 60 hp for the Avalon 18 ft. GS 2013 and 75 hp for the Avalon Windjammer - 18 Foot 2007. 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 8 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 Avalon Windjammer - 18 Foot 2007 comes in at 20 lbs per hp versus 27 lbs per hp for the Avalon 18 ft. GS 2013. 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 Avalon 18 ft. GS 2013 and Avalon Windjammer - 18 Foot 2007 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

The Avalon Windjammer - 18 Foot 2007 is the longer of the two at 18,0 feet overall. The Avalon 18 ft. GS 2013 comes in at 16,0 feet, making it roughly 2,0 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Avalon 18 ft. GS 2013 or the Avalon Windjammer - 18 Foot 2007?
For trailering, the Avalon Windjammer - 18 Foot 2007 has the edge at 1 491 lbs dry weight versus 1 600 lbs for the Avalon 18 ft. GS 2013. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Avalon Windjammer - 18 Foot 2007 is rated to a maximum of 75 hp, giving it the larger power ceiling. The Avalon 18 ft. GS 2013 tops out at 60 hp. Keep in mind that maximum ratings are just that - matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Avalon 18 ft. GS 2013 is Coast Guard rated for 8 passengers, while the Avalon Windjammer - 18 Foot 2007 is certified for 8. Note that legal capacity and comfortable capacity aren't always the same thing - on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.

The Avalon Windjammer - 18 Foot 2007 has a better power-to-weight ratio at 20 lbs per hp compared to 27 lbs per hp for the Avalon 18 ft. GS 2013. A lower number means quicker acceleration and faster time to plane - the number that actually matters most on short, sporty boats like these.
