Designer Name: Manuel "Manny" Caro (Mandala Custom Shapes)
Designer Origin: San Diego, California
Designer Bio: Caro pioneered the modern Twinzer fin setup—a two-fin system featuring a lead fin that compresses water flow over the trailing main fin to reduce cavitation and increase efficiency. His design methodology uses golden ratio proportions to govern the relationship between lead fin and main fin dimensions, creating a mathematically optimized alternative to traditional twin fins.
