Production began in 2005. Zim Sailing has since discontinued the Megabyte and groups it with the Byte, Zim 15, and Hartley as legacy classes that are no longer supported.
Design and Construction
The Megabyte has a solid-fiberglass hull and solid-fiberglass deck. Its broad side decks have chamfered edges. The side decks—and, in fact, the entire deck—are identical to those of the Tasar dinghy.
The cockpit is unusual. Its sides bond directly to the bottom of the boat, so there’s no cockpit sole as such. This creates what is described as a real cockpit, averaging 15 inches deep and noticeably larger than a Laser’s.
Both the daggerboard and dagger rudder are made from aluminum extrusions, keeping the appendages light and rigid. The Megabyte’s displacement is listed as identical to a Laser’s hull weight, but its larger hull has room for friends aboard.
Rig and Handling
The carbon-fiber mast carries 100 square feet of Mylar sail—20 square feet more than a Laser. A unique bungy cord set into the luff provides positive control of sail draft.
A traveler is fitted, and a second set of hiking straps is positioned forward for a crew member. The cat rig keeps deck handling simple when sailing singlehanded, while the additional sail area rewards careful weight placement and breeze.
With a sail-area-to-displacement ratio of 62.35, the Megabyte sits firmly among responsive, easily driven planing dinghies. Its 4.09 capsize ratio signals a boat designed for stability rather than offshore survival.
Cockpit and Daysailing
The Megabyte is an open dinghy with no conventional cabin or berths. Its size, however, makes it suitable for family daysailing. The real cockpit is deeper than a Laser’s, and the forward hiking straps allow an adult and a child or two to share the boat on short coastal outings.
Production and Ownership
Performance Sailcraft finished the boats at its plant. The company launched its 150th Megabyte and signed an additional hull-and-deck builder to meet demand.
Zim Sailing no longer produces the class, so owners rely on the legacy network and existing tooling for parts. The Tasar-derived deck also simplifies some aspects of composite repair for anyone familiar with that class.
The Verdict
The Zim Megabyte is a thoughtfully scaled singlehanded dinghy. It borrows a proven deck from the Tasar, adds a powerful Mylar sail and carbon mast, and has a listed displacement identical to a Laser’s hull weight while providing more room and sail area.
It’s a daysailing and teaching platform rather than a racer’s offshore weapon. Because the model has been discontinued, finding a clean example with sound aluminum appendages is especially important.
Pros
- Large, stable 14-foot, 3-inch singlehander with a 5-foot, 2-inch beam and 100-square-foot Mylar sail
- Tasar-identical deck and broad side decks ease handling and repair
- Aluminum daggerboard and rudder, carbon mast, and luff bungy for draft control
- Deep 15-inch cockpit and forward crew straps suit family daysailing
Cons
- No longer produced by Zim Sailing; it’s a legacy class with limited factory support
- Open dinghy with no enclosed accommodation
