When two boats share the same hull type — in this case both the Triton Boats 170 CC 2007 and the Triton Boats 18 Explorer 2008 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?

The power gap is worth calling out. Rated to 115 hp, the Triton Boats 18 Explorer 2008 has a 25-hp advantage over the Triton Boats 170 CC 2007's 90-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 Triton Boats 18 Explorer 2008 is rated for 550 passengers, while the Triton Boats 170 CC 2007 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Triton Boats 18 Explorer 2008 could be the deciding factor.
