But the US Navy turned down the idea of an 80 knot patrol boat, so the author turned to commercial products. In October 1955 he tested <i>SYNOTROPUSS<\/i>, an 8-foot rowboat with fiberglass foils and 7 hp outboard that made speeds over 30 mph. The next test craft was a 16-ft Goodyear family runabout fitted with foils that could do 34-mph. In August 1956, the author associated himself with Grumman Aircraft engineering Corp. After months of testing a foil-equipped 15-ft aluminum runabout in Florida, the Grumman boat was placed on the market at the New York Boat Show, January 1957. Unfortunately, &#8222;there were so many man-hours of labor involved in production it put the cost out of reach of the mass market.&#8220; At the time this article was written, a new type of mount had been developed to allow the Sea Wing foils to be attached to many makes of 14- to 16-ft runabouts.<\/p>\n<p>From:\u00a0<em>Carl, William P., &#8222;The Fantastic Hydrofoil Runabout &#8211; Its Development and Future&#8220;,\u00a0The Rudder, Aug 1958<\/em><\/p>\n<div class=\"mceTemp\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>How SEA WINGS hydrofoils developed from bathtub hobby to commercial reality. &#8222;This story begins in 1938, in Bob Gilruth&#8217;s bathroom&#8230; he started with 6-inch models&#8230;from the model tests, a full scale, 12-foot sailing catamaran with hydrofoils, CATAFOIL I was built and operated in the Chesapeake for several years.&#8220; The author started a collaboration with Bob [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":3548,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"advanced_seo_description":"","jetpack_seo_html_title":"","jetpack_seo_noindex":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[7],"tags":[588,333,16],"class_list":["post-3547","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-we-are-foiling","tag-catafoil","tag-history","tag-pioneer"],"acf":[],"jetpack_featured_media_url":"https:\/\/foilingweek.com\/wp-content\/uploads\/sites\/3\/2016\/01\/282eev.jpg","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/foilingweek.com\/de\/wp-json\/wp\/v2\/posts\/3547","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/foilingweek.com\/de\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/foilingweek.com\/de\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/foilingweek.com\/de\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/foilingweek.com\/de\/wp-json\/wp\/v2\/comments?post=3547"}],"version-history":[{"count":0,"href":"https:\/\/foilingweek.com\/de\/wp-json\/wp\/v2\/posts\/3547\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/foilingweek.com\/de\/wp-json\/wp\/v2\/media\/3548"}],"wp:attachment":[{"href":"https:\/\/foilingweek.com\/de\/wp-json\/wp\/v2\/media?parent=3547"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/foilingweek.com\/de\/wp-json\/wp\/v2\/categories?post=3547"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/foilingweek.com\/de\/wp-json\/wp\/v2\/tags?post=3547"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
