When two boats share the same hull type — in this case both the Princecraft Vectra 17 2010 and the Princecraft Vectra 17 L 2008 are pontoon designs with aluminum construction — 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 — Princecraft Vectra 17 2010 at 17,7 ft versus Princecraft Vectra 17 L 2008 at 17,0 ft. Weight tells a clearer story for trailering families: the Princecraft Vectra 17 2010 tips the scales at 1 312 lbs — 1 184 lbs more than the Princecraft Vectra 17 L 2008 at 128 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 — 50 hp for the Princecraft Vectra 17 2010 and 50 hp for the Princecraft Vectra 17 L 2008. 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.
For family outings this is probably the sharpest distinction between the two. The Princecraft Vectra 17 2010 is rated for 6 passengers, while the Princecraft Vectra 17 L 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft Vectra 17 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Princecraft Vectra 17 L 2008 comes in at 3 lbs per hp versus 26 lbs per hp for the Princecraft Vectra 17 2010. 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.
One place where both boats are genuinely identical is tube construction: both run 2 aluminum tubes at 23" diameter. That shared spec means stability and buoyancy characteristics are closely matched — the ride difference you'll feel between them comes primarily from deck length, weight distribution, and motor choice.
Bottom line: Choose the Princecraft Vectra 17 2010 if your priority is putting more people on the water — it handles 6 passengers and at 17,7 ft it has the deck room to back that rating up comfortably. The Princecraft Vectra 17 L 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
