TWIN CUMMINS 330HP 6BTA 5.9 DIESEL ENGINES with under 1500 hours!

The Ocean Alexander 420 Sundeck is an incredible and spacious Pacific Northwest cruiser that can accommodate all kinds of boaters: from liveaboards and year-round cruisers to summertime boaters and day trippers, this model pleases them all.  Her cockpit is perfect for fishing and crabbing and safely docking and getting on and off the boat - and her large aft deck is great for gathering to watch sunsets at cocktail hour - or the whales anytime you find them!  

This two stateroom, two head layout is great for cruising for two couples or the family, and with the convertible dinette opposite the galley, there's plenty of room to accommodate even more that want to visit and spend time with you out on the water.

Whether you want to spend months on end out on the hook exploring gunkholes - or host gatherings with all of your loved ones, the galley is fully equipped to handle even the most discerning of chefs, including an oven, large sized refrigerator / freezer, electric 3 burner stove / oven and some of the best counter space we have seen on a boat in the size range. 

Wow!  Some of the most beautiful, warm teak wood interior joinery you will ever see! 

Best of all, this boat has been repowered with reliable, economical and capable twin Cummins 6BTA 5.9 330hp Diesel engines with just under 1500 hours - not all 42' Ocean Alexanders are alike, and this one has everyone's favorite engines!
