Zodiac of North America, Inc., manufacturer of inflatable boats and rigid-hull inflatable boats (RIBs), announced a trade-in program for Avon and Zodiac jet-tenders in an effort to move the marketplace toward the more environmentally-friendly four-stroke models. "Our new four-stroke jet-tenders represent the latest technology, which in addition to maintaining their spirited performance, are also more in tune with today's environmentally-savvy customer," Gary Durnan, Vice President, Zodiac of North America, said. The trade-in program, Jet Set 5000, guarantees owners of Avon and Zodiac jet-tenders $5,000 for their trade to upgrade to a new four-stroke model.
