When two boats share the same hull type — in this case both the Hurricane Boats SD 187 I/O 2013 and the Hurricane Boats SD 237 OB 2011 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?

Size is the most obvious dividing line here. The Hurricane Boats SD 237 OB 2011 measures 23,2 feet overall (2011), giving it roughly 4,3 additional feet of deck space compared to the Hurricane Boats SD 187 I/O 2013 at 18,8 feet (2013). Weight tells a clearer story for trailering families: the Hurricane Boats SD 187 I/O 2013 tips the scales at 3 816 lbs — 3 771 lbs more than the Hurricane Boats SD 237 OB 2011 at 45 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 300 hp, the Hurricane Boats SD 237 OB 2011 has a 30-hp advantage over the Hurricane Boats SD 187 I/O 2013's 270-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Hurricane Boats SD 237 OB 2011 carries 61 gallons versus 49 gallons in the Hurricane Boats SD 187 I/O 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Hurricane Boats SD 237 OB 2011 is rated for 12 passengers, while the Hurricane Boats SD 187 I/O 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Hurricane Boats SD 237 OB 2011 could be the deciding factor.
