Detailed Evaluation & Buyer Recommendation
SeaArk Boats RX 180 Center Console 2022 vs SeaArk Cast & Blast 150 2010 — Same Brand, Different Boat
The SeaArk Boats RX 180 Center Console 2022 vs SeaArk Cast & Blast 150 2010 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.
The power gap is worth calling out. Rated to 70 hp, the SeaArk Boats RX 180 Center Console 2022 has a 30-hp advantage over the SeaArk Cast & Blast 150 2010's 40-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 SeaArk Boats RX 180 Center Console 2022 is rated for 5 passengers, while the SeaArk Cast & Blast 150 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk Boats RX 180 Center Console 2022 could be the deciding factor.
Bottom line: Choose the SeaArk Boats RX 180 Center Console 2022 if your priority is putting more people on the water — it handles 5 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The SeaArk Cast & Blast 150 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
