The Seafarer 34 has been built with more than one type of keel.
One option is a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a long keel.
Another option is a centerboard keel. A centerboard keel is a pivoting lifting keel, allowing to sail both coastal and inland waters.
The boat can enter even shallow marinas as the draft is just about 1.14 - 1.24 meter (3.74 - 4.04 ft) dependent on the load.
The boat is typically equipped with an inboard Universal Atomic 4 gasoline engine at 30.0 hp (22 kW), which gives a max speed about 5.7 knots.
