Colnago 39 is a purpose built aluminium luxury watertaxi designed and built to fulfil highest demands of VIP guests traveling across Croatian coast. Based on our SAR (search and rescue) craft, wessel capable of cruising at 30 knots speed in sea state 4 conditions giving it’s passengers smooth ride in 6 recaro style ergonomic seats.
Two diesel engines combined with waterjets make Colnago 39 more resistant to debris, sandbars and fishing tackle, making the vessel considerably safer at night and in limited visibility while giving maximum manouverability in tight spaces and shalow beaches.
Wessel has allready crossed more than 13000 nautical miles without any fault.

About Colnago 39S

Colnago 39S is a purpose built aluminum RIB which will be used as a support boat for a professional sailing team. The narrow concept with extreme rigidity of the hull combined with rubber “damper” give the smooth and dry ride during fast and slow operation. The specific use of the boat demanded special features like carbon fiber hard top to lower the center of gravity as much as possible, narrow steering console for storage of the sails on the sides, internal hanging points for frequent lifting, it fits into truck and it can be transported by road to any destination.


Why aluminium

Aluminum boats are in average 15-20 percent lighter than fiberglass boats. Weight advantage means that an aluminum craft of comparable design and equal strength will generally use less fuel if motor-driven, be able to accommodate a heavier cargo, and be more easily trailerable than its steel and fiberglass counterparts.
As for durability and reparability: aluminum comes out ahead of both steel and fiberglass. Compared with a steel hull, a “strength-equivalent” aluminum hull boasts about 29 percent greater dent resistance and 12.5 percent greater resistance to rupture.
Except for cosmetic reasons, 5xxx-series alloys don’t even have to be painted above the waterline; the unpainted metal reacts with air to form aluminum oxide – a hard, protective coating that protects the underlying aluminum. For most conditions the bottom of an aluminum hull needs only compatible antifouling paint to prevent the growth of performance-robbing barnacles and weeds and zinc anodes to prevent galvanic corrosion.
Why rubber
The rubber tubes absorb the wave energy and acts like damper providing smooth ride in rough conditions. It saves the boat from extreme stress during longer operation while giving higher stability factor, acts like a big fender when coming side by side with another boat or dock. The tube is divided into 8 airtight segments and the boat is practically unsinkable
