Building the boat is easy. The builder simply assembles the hull as a strip plank hull first, then glasses the outside and inside with fiberglass, to produce a strong composite hull without all the time consuming woodwork associated with traditional edge naile strip planking. Bog, fair, paint then time for the internals. Its that easy

For those that are interested, here's our "How to strip plank composite " video where I explain the process, whilst we built our own boat.

The following list of materials is approximate and intended for calculation of approximte 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 quanties for about 10% wastage. Resin and glass quanties are only approximate.

MDF Board (Temporary frames)
12mm (1/2") -8 sheets

30mm x 9mm  - 13 sq.m (146 sq.ft)

MARINE OR EXTERIOR BC GRADE PLYWOOD (Do not use CD structural plywood)
9mm (3/8") - 13 Sheets

RESIN AND GLASS (For coatings and reinforced areas)
Epoxy Resin & Hardener - 48 kg (12.7 US gal)
400-450gm (12oz) Double Bias - 50 sq.m ( 60 sq.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, a experienced builder 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.  

      BMD'S Strip Plank Composite Method of Building:

With the RipTide XR-457, we started with a fresh piece of paper and listened to what our clients wanted. One of the most common comments we hear is, "we're looking for a boat that can provide a smooth and comfortable ride, without ripping my spine out through the roof of my mouth". Make no mistake, the RipTide XR457 is a purpose-designed vessel. With her generous flare, 15 degree deadrise @ the transom, chine flats for stability and a 60 degree bow "Penetrating hull form", designed to slice through the waves, the RipTide XR-457 delivers top-end speeds, great handling through a variety of conditions and a ride unlike any other. So whether you're out boating in a blue sky day or punching through the grey horizons, the RipTide XR-457 is designed for those into serious small boating or offshore fishing.
