Description
I'm delighted to offer this beautiful Maxum 4200 which has been carefully maintained by the most amazing retired NASA astronaut and Shuttle Commander. You'll find extensive articles and interviews of this man online and it's evident that someone of his caliber has seen to the care of Sea Toy. Sea Toy spent most of her life on a lift in the Annapolis area, with only the last few years in Solomons, Maryland - the brackish water of the Chesapeake has only about 1/3 of the salt content of coastal and southern harbors.
The Maxum 4200 SCR is a proven winner produced from 2002-2006. With a 14' beam, Sea Toy gives you a lot of room and reduces the sea action for your seasick prone guests. Tall owners and guests have plenty of headroom in the 6'6" cabin and fully enclosed second cabin sports a solid wall and door - unlike the open 2nd berth of the Sea Ray or Cruisers - that gives your guests or kids complete privacy. Beautiful tiger maple finish throughout is in like-new condition and is brighter than the cherry finishes on competitor boats. The galley is efficiently and conveniently laid out so that you can move about as you're making a meal but nothing is in the way when you're not.
The high ceiling extends to the helm and cockpit affording high visibility and enclosures are bright and in great shape, giving you plenty of protection from the wind and rain. For kicks on the nice days, pull the bimini and show off the "floating hardtop" that none of your friends have. Good side walks take you up to the large foredeck with plenty of room for people to catch the sun, sunsets or fireworks.
The large extended swim platform would easily accommodate a dinghy or make easy boarding for kids, dogs or older guests. The aft seating section lifts hydraulically to give you massive entrance into the engine room, with plenty of elbow room and visibility to see all aspects of the engine compartment.

Purchasing my first boat came with a steep learning curve; the confusion, fear of asking questions, and unforeseen issues cost me peace of mind and an entire season of boating. That's why I'm passionate about assisting buyers and sellers, regardless of their experience level, to mitigate the risks involved. Boat ownership can be delightful, provided you can successfully steer through the uncertainties.
My personal boating history is evolving - we're currently preparing to trade our Sea Ray for a trawler. Some of my best memories are of chasing fish on a center console near Bloody Point, a grueling run from Annapolis to Middle River in heavy rain, 30 MPH winds and 8-foot seas, landing catfish with my grandson off the cockpit and watching ospreys teach their young to fish while I sip coffee with my lovely spouse in the fly bridge. What are some of your best memories . . . or dreams? Let's make that happen!
