28' Sonic USA 28SS 1997

$ 39,000

Owned and lovingly maintained for the last 13 years by a long time boating couple, always stored on her trailer and used in fresh water.  The boat looks like it came out of a time machine, so well kept and updated where needed (all her upholstery was replaced in 2014), she's impeccably clean and her hull and equipment devoid of boo boos, abuse or needs like you see in older boats. An open checkbook has always been there to do what's right for the boat.

Used exclusively as a cruiser (albeit one that happily cruises at 40mph), this 28SS was never ridden hard or used for poker runs.  Clean inside as she is on the outside, she has shore power and air conditioning.  A large custom cover stays on the boat when she's not in use. 

Her owners are finally looking to move up, and this classic ride could be your next boat.

The Sonic USA 28SS features unique construction techniques and innovative designs that have been developed by J. Ross over the past 20 years. Premium gelcoats, vinylester resin, Divinycell core, and biaxial glass are used to mold the three main components. The one-piece cabin, deck and hull are fused together, and all cavities are foam filled to create a lightweight super strong structure. The Sonic USA 28SS has maximum useable room, a high-tech look, and superior handling and performance.

Both long blocks were replaced in 2004 and have 139 hours on them.
