Canyon 456

456 Canyon Master of the Sea

I bought 2022 456 Grady White Canyon and received it in January last year. I was told the ride in a Grady is like no other. Having not ridden in one I was skeptical. I can now verify this boats ride is awesome and dry. It’s got to be a rough rough windy day to get wet. The Seakeeper works magic on the water keeping it from rolling side to side. It makes it easy to walk around the boat when fishing while trolling or bottom fishing. The 4-425 Yamaha Engines give the beast a ton of Power!

Canyon 456

Great Boat

The 456 Canyon is a very well built boat with the best delivered quality of any boat that I have ever bought. The few issues that I had (mostly my understanding of how things work) were promptly addresses by Caribee, my dealer. The boat is large and comfortable and has all of the features that I wanted in a boat that I mostly use for fishing (cooking a great lunch on the water is easy). I have had opportunity to use the boat on some pretty sporty days and it handles the water really well.
