For buyers looking for a sterndrive-powered deckboat in the 20-foot range that maximizes passenger space and comfort, the Glastron GTD 205 checks all the boxes — and does it in style. With an 8-foot, 6-inch beam that’s carried far forward, it is rated to carry 11 passengers, and there’s a seat for everyone. Glastron makes it easy for passengers to board via a stern walkthrough, but there’s also a flip-out gunwale section that lowers the gunwale’s height to allow boarders to easily step down on an intermediary step into the cockpit — something we’ve never seen on a boat this size. The step-down can be folded against the hull side and out of the way, so a rider can sit facing aft with her feet on the deck or put a cushion on it and recline.

Usually, when a boat this size has a sink with a spigot, it eats up valuable seating space, but on the 205 it’s tucked behind the full windshield. With the addition of an extended swim platform ($800), the stern section becomes an incredibly roomy place to hang out. Both platforms can be clad in Marine Mat for better traction and comfort, for $700.
The GTD 205 comes standard with a ski tow, but buyers can add a wakeboard tower ($1,967) that folds down with the help of gas struts. Skis and boards can be stored in a pair of optional tower racks ($600) or in the roomy in-floor locker. In the tower’s Bimini top is a drop-down changing room curtain. Thanks to the weight of the sterndrive engine and the SSV hull design, at around 20 mph the GTD 205 creates a surprisingly clean wake for launching. At 30-plus mph the wake flattens out for slalom skiing. An available fishing package ($3,467) includes a front casting platform with a seat, a livewell and a fishfinder. Another $1,267 adds a trolling motor.
The SSV hull is known for its quick-planing and cornering ability, and with a new-gen MerCruiser 4.5L V-6, the GTD 205 got on plane in 3.2 seconds and reached 30 mph in 7.1 seconds. Top speed touched 44.5 mph. Glastron also offers Volvo Penta power, a 280 hp V-6 that is $1,782 more than MerCruiser’s 250.
