Just saw this brought to the top, Louis Durand built the Water Spiders for over a decade, solid shaft boats, tub nose length same length as the front of front sponsons, Coyote had protruding pointy front sponsons. Both boats were "low slung" when running, unlike the Crapshooters of the day that sat farther off the water when running. The Water Spider was born of a boat called the Climax from the east coast. The design was purchased by Louis from the Beard brothers, much work and a few mods later he released the Water Spider in kit form with excellent instructions. I was privileged to be around and learning in the mid 1970s as this hull was developed. The Water Spider was made with solid shafts and solid mounts. Don Wagner started developing and then producing the Avenger line of hydros, flush transom, wood/glass cowls, first solid then flex shafts, first solid mounts then rubber mounted engines in the very late 1970s. One of his first Avenger hulls was named "Incubus" with a very dark paint job and was campaigned as the club (SGRA) pond moved across the street to the KOA Campground from its home at Millers Pond in Hammond, (yes, where the infamous around the island race took place, ask Johnny Ackerman) Don moved to primarily yellow hulls and his right hand at the time, Joe D. ran red with black trim hulls. Don lent me a beautiful 7.5 outboard Avenger rigger that was used in some advertising of his to run on one of our trips to Houston for their spring race. The boat held its own with the 45 riggers but I was not that great a driver back then. He gave me the hull upon our return to New Orleans and I wish I still had it. Eventually Don bought Water Spider from Louis and production was named Avenger/Spider, hulls had the A/S stamp inside. The melding of the hulls produced the Avenger/Spider line of hydros, this also was the start of the recessed transom. Always working on improvements, Don would make mods for testing, some of us got these hulls from him, I have a 45 size and was called it the A/S Cobra. His final design 20 rigger ended up with a top line of the side drop at the engine mount with a flat deck over the fuel tank and was also known as the A/S Cobra 20. I have 7 of these hulls. I have a set of the templates from Water Spider and also Avenger, the boats I now cut out for us and a few friends are modified A/S design, narrower tub, wider footprint, much smaller rears. Got the itch and cut out a few .12 sized boats a few weeks ago just for us and some friends. They are in various stages of construction on the framing bench now. If ever sold, (doubtful) they will carry the Oval Master name as we still make that line of fiberglass hulls as purchased from Don in 1999. Just a short bit of history from this aging mind.
