Cathedral Hull Boats
Flat Bottom Cathedral Hull Range
Port Edward Boat Builders have a range of traditional shaped cathedral hull boats in a range of sizes
and specifications.
The Range starts with a flat bottom Cathedral Hull form. 3.0m x 1.5m 4 person boat. This simple
sturdy construction is more fuel efficient than the skiffs and suitable for engines up to 15HP.
The bottom shell is supported by two formed box section keels.
This Boat is finished with a carpet, permanent reserve buoyancy and as specified by the owner.
These boats are available in 3.0m 3.5m 3.7m 4.0m and 4.5m
Cathedral Hull Boats with 5 degree Rise of Floor
Traditionally boats are constructed with a keel. Our traditional designed Cathedral Hull Boats are
available with a 5 Degree Rise of Floor, 10 Degree Rise of Floor and 15 Degree Rise of Floor V Bottom
Hulls. The choice of Hull form is dependant on the conditions and size of your boat.
Larger boats operating in rough open waters such as large dams are best designed with a 10 to 15
degree vee bottom hull form, giving good separation of flow either side of the keel. This leads to
increased rolling. Rolling can be dampened by increasing the width aft.
