Just a few months earlier we tested Sea Ray's 310 Sundancer, which achieved nearly identical performance as the Rinker, topping out at 45.1 mph with twin 260 hp MerCruiser 5.0L MPI Seacore Bravo Three sterndrives ($172,900). These netted about 15 percent better economy across the cruising band. It carries 6 inches less beam and is some 600 pounds lighter. still, the 350 MAGS in my Rinker, also available for the Sea Ray, might be a better choice in real-world conditions: loaded with owner gear, a full crew, the canvas erect and sporting some bottom growth. (In fact, I tested the Rinker in the swell and chop of Lake Erie, while the Sea Ray test was conducted on the flat water of Tennessee's Little Tellico River, showing how performance varies with power and sea conditions.) Sea Ray's bow access was easier, though the transom platform stowage held some water, whereas that aboard the Rinker drained completely. The Sea Ray has a neat dinette booth instead of the traditional settee found aboard the Rinker. Sea trial both and you make the call.
