When two boats share the same hull type — in this case both the Crestliner Fish Hawk 1600 Tiller 2011 and the Crestliner TC 18 2012 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 — Crestliner Fish Hawk 1600 Tiller 2011 at 16,0 ft versus Crestliner TC 18 2012 at 18,3 ft. Weight tells a clearer story for trailering families: the Crestliner TC 18 2012 tips the scales at 1 044 lbs — 961 lbs less than the Crestliner Fish Hawk 1600 Tiller 2011 at 83 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 90 hp, the Crestliner TC 18 2012 has a 30-hp advantage over the Crestliner Fish Hawk 1600 Tiller 2011's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 23 gal and 22 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Crestliner Fish Hawk 1600 Tiller 2011 is rated for 5 passengers, while the Crestliner TC 18 2012 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Fish Hawk 1600 Tiller 2011 could be the deciding factor.
Bottom line: Choose the Crestliner Fish Hawk 1600 Tiller 2011 if your priority is putting more people on the water — it handles 5 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Crestliner TC 18 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
