Here is a model of a modern catamaran that lets you create multiple versions of the catamaran with different sail and hull patterns. There are enough options for changing the colors and patterns of the pontoon hulls and sails to allow you to populate an entire sailboat race scene.
The catamaran comes with four different hull patterns and three different sail patterns as shown in some of the images below. These patterns are accessed by making some simple choices in the Material Editor as explained in the included "Readme" file (and as shown on some included illustrations). In addition, you have access to many parts of the hulls and sails so that you can apply color schemes of your own choosing to the boat.
To accommodate poses with human figures, you can lift and rotate the long rudder extension handle.
Cook's Catamaran also includes a foam wake for use when the boat is traveling over relatively flat water at high speed.
