The C21 is a true offshore boat with just the right hull shape for fishing or family outings.
The proven hull shape with a typical 12 degrees moderate vee is has sufficient deadrise to run smoothly in bad weather but is moderate enough to provide good stability at slow speed without the wild roll typical of deeper vee hulls.
The generous freeboard and the classic sheer are also tried and true features contributing to seaworthiness. This boat will negotiate both head and following seas with ease. While it is not very clear on the pictures, the C21 (just as the C19), has a styleline in the topside. Not only does it add strength but it is esthetically pleasing and easier to build.
The self bailing cockpit has a minimum of 30" with 12" wide gunwales, is another important element of safety. Thanks to the freeboard and transom design, she can be rated to a max. capacity of eight persons (USCG) and we recommend engines in the 90- to 125 HP range. While stronger than the typical production fiberglass boat of that size, she is also lighter and does not require as much HP (or fuel) to cruise at the same speed: a 70 HP will get her on plane.
With 4 persons and gear, rigged with a 90 HP, she will do 30 mph and up to 37 with a 125 HP. Those are very conservative figures and with some tinkering and attention to weight, she will go much faster. The 80 gallons of fuel (in two standard tanks) will give her the range required for long offshore runs.
This boats transom is designed for a standard 25" shaft. The transom can easily be modified to accept other shaft lengths.
The first option to consider should be positive and upright buoyancy (unsinkable boat). This can easily be easily achieved with our marine flotation foam. For production boats in that size, the USCG requires upright floatation.
The basic center console layout is ideal for the fisherman. A cooler under the swing back seat, baitwell in the forward part of the console of better, in one the stern lockers, fish box and storage under the casting deck, rod holders under the gunwales.
The plans include a standard center console drawing with dimensions to cut all parts.
A pilothouse style console can be fitted as an option. Our console plans show 3 different types. The picture below shows the reverse rake model.
For family outings, we may want more seating. Some of our pictures show optional quarter seats but a fixed or removable bench can also be installed all across the boat, in front of the motor well. An outboard bracket can be used to free even more space for storage in the stern. Some details can be changed or added. Standard bow pulpits, T-tops or bimini tops, windshields are easy to fit.
A last option is a twin engine layout. The plans show two different motorwells: one for a single outboard with a standard 25" shaft and an optional twin engine motorwell. Each layout is compliant with international industry standards: all recent outboards will fit.
