When two boats share the same hull type — in this case both the Hurricane Boats SD 187 I/O 2012 and the Hurricane Boats SS 188 I/O 2013 are tri-hull designs with fiberglass 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 — Hurricane Boats SD 187 I/O 2012 at 18,8 ft versus Hurricane Boats SS 188 I/O 2013 at 18,8 ft. At 3 816 lbs and 3 816 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 — 270 hp for the Hurricane Boats SD 187 I/O 2012 and 270 hp for the Hurricane Boats SS 188 I/O 2013. 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 carry nearly identical fuel loads — 49 gal and 49 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Hurricane Boats SS 188 I/O 2013 is rated for 10 passengers, while the Hurricane Boats SD 187 I/O 2012 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Hurricane Boats SS 188 I/O 2013 could be the deciding factor.
Bottom line: Choose the Hurricane Boats SS 188 I/O 2013 if your priority is putting more people on the water — it handles 10 passengers and at 18,8 ft it has the deck room to back that rating up comfortably. The Hurricane Boats SD 187 I/O 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
