One note of caution about the spade rudder is important. The same rudder was used on both the shoal and deep draft models of this boat and, on the shoal draft model, the rudder is nearly exactly the same depth as the bottom of the keel. This leaves the rudder quite vulnerable to damage by grounding even in the rather soft bottom of the Chesapeake Bay. This is sufficient power for the size and weight of the boat. The engine is installed beneath the bridgedeck, and to the delight of mechanics and surveyors, the installation is not crowded.
Access is good to all sides of the engine.
Like most of O'Day's cruising designs, the 34 is aimed at moderate sailing performance and spacious accommodations. By 1981 standards, the hull form is quite beamy however, there are no extremes in shape to produce poor sailing performance or erratic behavior. The deep draft keel is a moderate aspect fin for good windward performance and the rudder is large for good control. Overhangs are short resulting in a reasonably long sailing length. There is a V-berth cabin forward followed by head to port and hanging lockers to starboard.
