When two boats share the same hull type — in this case both the MirroCraft 3673 (16 ft. Laker II) 2010 and the MirroCraft Utility V - 4604 2009 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 3673 (16 ft. Laker II) 2010 at 16,2 ft versus MirroCraft Utility V - 4604 2009 at 14,0 ft. Weight tells a clearer story for trailering families: the MirroCraft Utility V - 4604 2009 tips the scales at 175 lbs — 171 lbs less than the MirroCraft 3673 (16 ft. Laker II) 2010 at 4 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 40 hp, the MirroCraft 3673 (16 ft. Laker II) 2010 has a 25-hp advantage over the MirroCraft Utility V - 4604 2009's 15-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The MirroCraft 3673 (16 ft. Laker II) 2010 is rated for 5 passengers, while the MirroCraft Utility V - 4604 2009 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 (16 ft. Laker II) 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The MirroCraft 3673 (16 ft. Laker II) 2010 comes in at 0 lbs per hp versus 12 lbs per hp for the MirroCraft Utility V - 4604 2009. 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 (16 ft. Laker II) 2010 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 Utility V - 4604 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
