Purchase includes 2D drawings that provide specifications, material lists and dimensional information to permit construction. Also included is a builders guide with suggestions to aid with construction. All plans include 8 hours of free consultation and supplemental drawings and 3D model information at our discretion.
Preliminary design work on a 10 meter (33 foot) performance boat has been done based on the Rossi 7.50 Sportboat concept combined with the Rossi 33 R/C sailplan. One significant difference for this design is the hull shape below the chine. Here an arc shape is being proposed to appeal to those that like curved shapes, but more importantly to obtain a little more hull efficiency by further reducing hull drag and increase hull stiffness without additional structural reinforcement. Construction is intended to be done using foam and fiber composites without the need for a female mold. Preliminary lightship displacement estimates are in the 1600 Kg (3500 lb) range.

ROSSI 7.5 Sportboat
Rossi Engineering has prepared a preliminary design for a high performance 7.5 meter sportboat. The target displacement for this design is 1000 lbs which will require using carbon fiber constuction for the hull and deck panels as well as for all interior structural elements. The spars will be carbon fiber with a single set of 20 degree swept spreaders with high modulus fiberous material for the standing rigging and no permanant backstay. The keel foil structure will be made of carbon fiber with a a lead bulb attached to the tip of the foil to maximize the amount of ballast placed as low as possible. This design is also intended to be built using e-glass/foam or marine plywood to provide lower cost construction alternatives, but with an increase in weight.

ROSSI 35 Sportboat
Rossi Engineering has prepared a preliminary design for a high performance 35 foot sportboat. The target displacement for this design is 5000 lbs which will require using carbon fiber constuction for the hull and deck panels as well as for all interior structural elements. The spars will be carbon fiber with a double pair of 20 degree swept spreaders with high modulus fiberous material for the standing rigging and split backstays. The keel foil structure will be made of carbon fiber with a a lead bulb attached to the tip of the foil to maximize the amount of ballast placed as low as possible. This design is also intended to be built using e-glass/foam or marine plywood to provide lower cost construction alternatives, but with an increase in weight.
