When two boats share the same hull type — in this case both the MirroCraft 3654 (14 ft. Deep Fisherman) 2013 and the MirroCraft 3673 2011 are modified vee designs with aluminum 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 — MirroCraft 3654 (14 ft. Deep Fisherman) 2013 at 14,2 ft versus MirroCraft 3673 2011 at 16,2 ft. At 29 lbs and 4 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 — 25 hp for the MirroCraft 3654 (14 ft. Deep Fisherman) 2013 and 40 hp for the MirroCraft 3673 2011. 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.
For family outings this is probably the sharpest distinction between the two. The MirroCraft 3673 2011 is rated for 5 passengers, while the MirroCraft 3654 (14 ft. Deep Fisherman) 2013 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the MirroCraft 3673 2011 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The MirroCraft 3673 2011 comes in at 0 lbs per hp versus 1 lbs per hp for the MirroCraft 3654 (14 ft. Deep Fisherman) 2013. 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 MirroCraft 3673 2011 if your priority is putting more people on the water — it handles 5 passengers and at 16,2 ft it has the deck room to back that rating up comfortably. The MirroCraft 3654 (14 ft. Deep Fisherman) 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
