The Kite, an 11.58foot monohull sailboat, embodies the spirit of a nimble onedesign racer designed for competitive and spirited sailing. Conceived by designer Carter Pyle, this compact vessel was introduced in 1965 and quickly established itself as a popular choice for sailors seeking a lively and responsive racing dinghy. Built by both Newport Boats in California and Mobjack Manufacturing Corp. in Virginia, the Kite reflects a period of innovation in small boat construction, utilizing fiberglass for durability and low maintenance.

History and Design

The genesis of the Kite dates back to 1965, when Carter Pyle introduced his design as a dedicated one-design racer. This timing aligned with Mobjack Manufacturing Corp.'s established ethos of pioneering fiberglass construction for small, performance-oriented sailboats, as evidenced by their earlier Mobjack dinghy. Roger Moorman, the founder of Mobjack Manufacturing Corp., was a proponent of modern materials, favoring fiberglass over traditional wood to create robust and easily maintained vessels. The Kite's construction in solid fiberglass for both hull and deck material showcases this commitment to durability and consistency, crucial for a one-design class where uniformity of equipment fosters fair competition. The involvement of Newport Boats as another builder further broadened the Kite's reach within the sailing community.

Sailing Performance and Handling

Given its compact size, with a length overall of just under 12 feet and a displacement of only 165 pounds, the Kite is designed for agile and exhilarating performance. As a small sailing dinghy, traditional performance ratios like sail area to displacement or ballast to displacement are less applicable. Instead, its cat-rig configuration and daggerboard keel contribute to its characteristic responsiveness. The narrow beam of 5.0 feet, combined with its light displacement, suggests a boat that is quick to accelerate and highly sensitive to crew input. Anecdotal descriptions suggest the Kite "flies" under sail, indicating a lively and enjoyable sailing experience. With a theoretical hull speed of 4.43 knots, the Kite is built to be a fast and competitive entry in its class, offering engaging handling for both racing and recreational day sailing.

Accommodations and Layout

As a dedicated one-design racing dinghy, the Mobjack Kite is designed for performance rather than extended cruising accommodations. Consequently, it features an open cockpit layout without any interior cabin or headroom. The design prioritizes a functional and uncluttered space for the crew to manage sails and control the boat efficiently during races. The fiberglass hull and deck provide a low-maintenance platform, typical of its era for small racing dinghies. The cockpit would offer seating for the crew, with essential lines and controls easily accessible for quick adjustments, reflecting its purpose as a responsive and competitive sailboat.
