A live-data comparison like Alera M23l vs Sea Pro 172-Bay gives boats buyers a more realistic picture than spec sheets alone — the prices shown here reflect actual dealer asking prices, not MSRP. When evaluating boats at this price point, experienced buyers typically weigh hull condition, engine hours, trailer integrity, and storage footprint alongside the headline number. The Sea Pro 172-Bay currently carries the lower median asking price, which compounds meaningfully over a 48-to-72-month financing term — even a modest gap per month adds up to hundreds of dollars by payoff. Broader selection from the Sea Pro 172-Bay side gives buyers more negotiating room and reduces the chance of settling on a unit that's slightly off on color, trim, or mileage. A pre-purchase survey from a certified marine surveyor is strongly recommended for any used boat purchase — surveyors routinely surface osmotic blistering, hidden transom rot, and electrical faults that are invisible at dockside. Slip or dry-storage fees, winterization, and annual engine service add meaningfully to the cost of ownership, so verify what those run in your area before making a final budget decision between these two models.
