When two boats share the same hull type — in this case both the Sea Hunt Super Skiff 21 2010 and the Sea Hunt Ultra 186 2010 are modified vee 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 — Sea Hunt Super Skiff 21 2010 at 21,1 ft versus Sea Hunt Ultra 186 2010 at 18,5 ft. At 19 lbs and 18 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.
The Sea Hunt Ultra 186 2010 tops out at 150 hp. Engine specs for the Sea Hunt Super Skiff 21 2010 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Sea Hunt Ultra 186 2010 carries 58 gallons versus 4 gallons in the Sea Hunt Super Skiff 21 2010. 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 Sea Hunt Super Skiff 21 2010 is rated for 6 passengers, while the Sea Hunt Ultra 186 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Hunt Super Skiff 21 2010 could be the deciding factor.
Bottom line: Choose the Sea Hunt Super Skiff 21 2010 if your priority is putting more people on the water — it handles 6 passengers and at 21,1 ft it has the deck room to back that rating up comfortably. The Sea Hunt Ultra 186 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
