Cruise Control 5.2 Construction

                            Arrangement

     The requirement for the Cruise Control 5.2 was simple. It had to be light, quick to build, easy on the pocket, a deep "V" hull and yet still retain its strength, seaworthiness and performance. The Cruise Control 5.2 plywood version is built from Marine plywood, epoxy, and directional E-glass fabrics, constructed using the Stitch & Tape. THe strip plank compostie version is built from strip plank and directional E-glass fabrics, both methods resulting in a stronger, tougher and more durable boat, while still retaining their lightweight constructions.    

                            Construction

        For the arrangement plan, a question most asked of us is, could we please  include a private area in regards to the toilet arrangement, not only for guests but more importantly... the opposite sex. So in this regard, we made this one of our  top prioritys with this design, using real walls and not flapping curtains to the outside world.                      

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 timber in the construction of hull, deck and interior, including building stocks, temporary bracing etc. Allowance has been made in the quantities for about 20% wastage.

STRUCTURAL PLYWOOD OR PARTICLE BOARD
8ft by 4ft (2.44 x1.22m) 12mm (1/2") - 2 sheets

Epoxy resin & Hardner - FGI R180/ H180- approx 96 kg
450g/sq.m Double Bias - approx 90 sq m
(Cheaper to purchase the items listed below in 10 kg bags- you will have left overs, but overall far cheaper than smaller quanties)
Glue powder 10 kg
Fairing powder 10 kg (Q-cells, Microballoons or similar)

                            Design

       In regards to design of the hull, the Cruise Control incorporates a sharp high entry angle at the bow and a 20 degree deep-V hull form at the transom, delivering a smooth dry ride by displacing water away from the boat, while a wide bow flair keeps it from rolling back into the boat. Also by featuring a higher degree of deadrise at the transom, this provides added stability in rougher seas.

        Also the large chines on the Cruise Control 5.2 hull form, deflects water down and under the hull, acting as two points on which it balances. These points provide a great deal of dynamic stability for a more solid ride while also increasing lift and reducing drag for a faster more efficient running hull.
