THE RIPTIDE CX-457
For our builders we offer full size printed bulkhead/ frame patterns, printed on 24" wide paper which are taped together to provide fulls size outlines. Using the full size patterns and detailed plan sheets, the parts can be accurately marked and cut out. All Plan sheets are printed on Architectural D (24" x 36" ) paper except for the full size frame patterns.
"No hassles" doesn't mean "no frills" when it comes to the RipTide CX457, this boat packs a lot of amenities for fishing, cruising and watersports enthusiasts and is a small boat designed on big ideas.
Offering the features and functionality typically only found in much larger boats, the RipTide CX457's compact size means she can be easily trailered to where the action is - whether it be diving, exploring a secluded beach, fishing or... just simply relaxing on the water.

MATERIALS LIST FOR THE RIPTIDE CX-457
The following list of materials is approximate and intended for calculation of approximate costs. We offer no guarantees of accuracy. The list is for all plywood in the construction of the hull, deck and interior. Allowance has been made in the quantities for about 10% wastage. Resin and glass quantities are only approximate.
CHIPBOARD OR MDF (For the temporary frames)
8x4ft sheets (2.44 x 1.22m) 12mm (1/2") - 8 Sheets
WESTERN RED CEDAR, PAULOWNIA OR SIMILAR TIMBER. You can even strip plank from plywood ! (Planking)
30mm x 9mm - 13 sq.metres/ (1-5/8 “ x 3/8 “ - 146 sq.ft)
MARINE BS 1088 OR AB GRADE PLYWOOD (Density no less than 500 kg/m^3 or 31.2 lbs/ft^3)
9mm (3/8") - 13 Sheets
12mm (1/2”) – sheets
RESIN AND GLASS (For coatings and reinforced areas)
Epoxy Resin & Hardener - 72 kg ( 19 US gal)
400-450gm (12oz) Double Bias (not Biaxial) - 60 m ( 66 yards)
2 kg (4.4 lbs) glue powder (Cabosil)
2kg (4.4 lbs) Q-cells (fairing Powder)
The materials list above covers all the supplies for the boat as designed.
Useage of materials may vary due to several factors. For example, experienced builders will use less resin. Our resin calculations are based on a 50% glass content. Options, customization and variations within your build will also effect the bill of materials and outcome.
Anyone can Build a Boat. Its that Easy
Just about anybody can build a boat using the Bowdidge Marine Design Plywood Composite system. This method eliminates many members that ordinarily require fitting, fairing, and beveling. Thus, it's ideal for beginners. A jigsaw and drill are about the only power tools required. The resulting boat is incredibly light weight, strong, and durable.
This quick and easy boatbuilding method consists of laying the planks onto the temporary frames, allowing the planks to "find their own way" from bow to stern. We also use tile spacers to provide the gaps between the planks to push the glue through at a later stage. Once the planks are fixed into position, we can then begin gluing the planking into place. By doing things this way, we're not under pressure to plank up fast due to the glue going off, but working at our own pace. It also means that the planks themselves are not tortured into position, using clamps or whatever to hold down, but the planks "naturally" want to lay down as they ar laying naturally of finding their own path. Its that easy. (see video below)
Once the planks have been glued, its time to give teh hull a quick fair with your sander, then time to begin glassing.
Plans for all our designs include instructions, material layouts, and material listings. In addition, the patterns provided are precise, since they're taken from the actual 3D modeling and CAD systems.
