The O'Day 19 is an American trailerable sailboat that was designed by John Deknatel of C. Raymond Hunt Associates, as a racer-cruiser and first built in 1979.
It has a fractional sloop rig, a raked stem, a slightly reverse transom, a transom-hung rudder controlled by a tiller and a fixed stub keel, with a centerboard.
O'Day may have hoped that they could start some fleets for one-design club racing, but the boat is probably a bit too small for that purpose, given her relatively short cockpit and lack of buoyancy aft (insufficit to support much crew weight).
Worst features: the O'Day’s average PHRF of around 218 compared to much higher numbers for her comp[etitor]s would indicate that she is a faster boat.
Other faults include an awkward mainsheet lead (with no traveler to keep the boom in close in a breeze) and a rudder whose bottom is lower than the keel with board up (asking for trouble in shoal waters).
