Detailed Evaluation & Buyer Recommendation
Princecraft Fish n' Promenade SP 186 FNP I/O SE 2005 vs Princecraft PR 1852MT 2010 — Same Brand, Different Boat
The Princecraft Fish n' Promenade SP 186 FNP I/O SE 2005 vs Princecraft PR 1852MT 2010 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 — Princecraft Fish n' Promenade SP 186 FNP I/O SE 2005 at 18,0 ft versus Princecraft PR 1852MT 2010 at 18,0 ft. Weight tells a clearer story for trailering families: the Princecraft Fish n' Promenade SP 186 FNP I/O SE 2005 tips the scales at 2 445 lbs — 1 970 lbs more than the Princecraft PR 1852MT 2010 at 475 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 220 hp, the Princecraft Fish n' Promenade SP 186 FNP I/O SE 2005 has a 175-hp advantage over the Princecraft PR 1852MT 2010's 45-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Princecraft Fish n' Promenade SP 186 FNP I/O SE 2005 is rated for 8 passengers, while the Princecraft PR 1852MT 2010 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft Fish n' Promenade SP 186 FNP I/O SE 2005 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Princecraft PR 1852MT 2010 comes in at 11 lbs per hp versus 11 lbs per hp for the Princecraft Fish n' Promenade SP 186 FNP I/O SE 2005. 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: Choose the Princecraft Fish n' Promenade SP 186 FNP I/O SE 2005 if your priority is putting more people on the water — it handles 8 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Princecraft PR 1852MT 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
