The SeaArk Cast & Blast 150 2007 vs SeaArk Stealth 172 2009 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.

On paper these two are close siblings in the size department — SeaArk Cast & Blast 150 2007 at 15,0 ft versus SeaArk Stealth 172 2009 at 17,0 ft. Weight tells a clearer story for trailering families: the SeaArk Stealth 172 2009 tips the scales at 925 lbs — 870 lbs less than the SeaArk Cast & Blast 150 2007 at 55 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.

Bottom line: The SeaArk Cast & Blast 150 2007 and SeaArk Stealth 172 2009 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
