When two boats share the same hull type — in this case both the Palm Beach Fishing 173 Whitecap 2010 and the Palm Beach Fishing 1800 DL 2009 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 — Palm Beach Fishing 173 Whitecap 2010 at 17,0 ft versus Palm Beach Fishing 1800 DL 2009 at 17,0 ft. Weight tells a clearer story for trailering families: the Palm Beach Fishing 173 Whitecap 2010 tips the scales at 1 375 lbs — 1 190 lbs more than the Palm Beach Fishing 1800 DL 2009 at 185 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 115 hp, the Palm Beach Fishing 1800 DL 2009 has a 25-hp advantage over the Palm Beach Fishing 173 Whitecap 2010's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 35 gal and 35 gal — so range won't be a tiebreaker here.

Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Palm Beach Fishing 1800 DL 2009 comes in at 2 lbs per hp versus 15 lbs per hp for the Palm Beach Fishing 173 Whitecap 2010. 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.
