Outboard Performance Inflatables

"There Are Ducks On Our Race Course"

No, not the feathered kind of bird but the performance outboard inflatable kind that fly. These boats are being imported from South Africa and go by the name of DUX, THUNDERDUCKS, THUNDERCAT and GEMINI. In South Africa they have a racing program for these performance inflatables which has over 300 registered boats competing in surf racing in the ocean, along with river and inland lake racing.

These boats have evolved for the past 12 years in South Africa for competitive racing purposes. They weigh around 165 pounds, have a 11 inch deep tunnel, collapsible floor boards, flow through aluminum transom, 70 hp Max rating, fiberglass front wing, 7 air chambers and heavy-duty rubber strakes. The boats measure 13' long and have a 6' beam. The cost to go racing is nominal and the motors are readily available as tourist motors. No racing or specialty motors are allowed in the two classes available, allowing these boats to serve dual purpose as a race & pleasure craft.

OPI's seem to be a cross of OPC, offshore, and stock outboard. They fly and turn like a OPC boat and there is a pilot and co-pilot who work together like in offshore. These boats have the same rough water capabilities as an offshore does (races have been run in 40 mph winds and 15 foot waves in South Africa). Their handling is very weight sensitive (the reason for a co-pilot) as it is in stock outboard. The only thing it does not have in common is the price and the amount of work it takes to go racing. Since this is a performance rig it requires skill to run, and they can blow over, spin out or flip. The danger is reduced as these boats are pvc material filled with air but there are still spinning exposed props.

In South Africa their circuit includes divisional and national circuits. The national circuit includes surf racing, where the course is set up right off the beach where the waves break, and long hauls where the course goes for 100 miles in the ocean. Inland lake racing is on a closed course as well as river racing. They also have a once a year race that goes over 5 days from city to city running the boats along the coast. The attrition rate is very low, only 5%. The construction of these craft are built to endure the most extreme conditions.

There are two classes offered. BANDIT class which allows a 34 cid (550cc) motor. This class will power the boat with a two person crew to speeds of 45 mph. The second class that is being offered at this time is "OUTLAW" class, it allows for a 46 cid (750cc) motor. "B" class can reach speeds of near 60mph. All the motors perform the best with a 15" shaft motor. If the interest is there we will include classes that will allow for performance modifications. The pilot must be of 18 years old and the co-pilot must be at least 14 years old. We are encouraging family teams (father-son, mother-daughter, husband-wife, boy friend / girl friend ect.). Currently we have one husband-wife team and one father-son team with a few more family teams being formed at this time.
