The Crest Savannah LS 20 2007 vs Crest Sport Fisherman 18 4CL 2005 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Crest Sport Fisherman 18 4CL 2005 measures 18,0 feet overall (2005), giving it roughly 16,0 additional feet of deck space compared to the Crest Savannah LS 20 2007 at 2,0 feet (2007).

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 Crest Savannah LS 20 2007 has a 40-hp advantage over the Crest Sport Fisherman 18 4CL 2005's 75-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 Crest Savannah LS 20 2007 is rated for 13 passengers, while the Crest Sport Fisherman 18 4CL 2005 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crest Savannah LS 20 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crest Sport Fisherman 18 4CL 2005 comes in at 23 lbs per hp versus 25 lbs per hp for the Crest Savannah LS 20 2007. 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.
