The Chaparral Boats Signature 310 1997 is the longer of the two at 31,0 feet overall. The Chaparral SSi 186 2010 comes in at 19,5 feet, making it roughly 11,5 ft shorter — a meaningful difference in deck room and overall on-water presence.

The Chaparral Boats Signature 310 1997 is rated to a maximum of 350 hp, giving it the larger power ceiling. The Chaparral SSi 186 2010 tops out at 225 hp.

The Chaparral Boats Signature 310 1997 is Coast Guard rated for 9 passengers, while the Chaparral SSi 186 2010 is certified for 9.

Yes — both the Chaparral Boats Signature 310 1997 and the Chaparral SSi 186 2010 are built by Chaparral.

Detailed Evaluation & Buyer Recommendation

Chaparral Boats Signature 310 1997 vs Chaparral SSi 186 2010 — Same Brand, Different Boat

The Chaparral Boats Signature 310 1997 vs Chaparral SSi 186 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.

The power gap is worth calling out. Rated to 350 hp, the Chaparral Boats Signature 310 1997 has a 125-hp advantage over the Chaparral SSi 186 2010's 225-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

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 Chaparral Boats Signature 310 1997 at 31,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Chaparral SSi 186 2010 at 19,5 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.
