Marlin 300

Third Grady White

I’ve owned many boats from 13’ to 35’. I’ve upsized and downsized many times. Many years ago I owned a GW Sailfish 282. I loved that boat. After many in between, I have settled once again with the Marlin 300. It’s the perfect boat for us. We thought the Gulfstream 232 was going to work well but after two seasons, found more room was needed. This is a keeper. A fantastic riding boat with a few nice amenities that make cruising with friends or family very comfortable and enjoyable.

We purchased a new 2022 Marlin 300 from South Shore Marine. What a great boat for the rough water of Lake Erie. The fishing features coupled with the ability to overnight sold us on the Marlin. Matt our sales person from South Shore has been excellent and professional both before and after the sale, Our experience with both Grady White and South Shore has been great. Grady White builds a top quality boat. Martha and Pascal.
