I have used several Barrett and Maxiprops over the years, and have found them to be VERY inefficient compared to a fixed pitch (like 2.5 knots worth) It always seemed to me that a feathering prop with a little twist would be the answer, but I didn&#8217;t know that they existed until I saw reference to it in your book. If it&#8217;s not too much problem, do you also have a source for your &quot;Murphy&quot; gauges? <\/p>\n<\/div>\n<p><!--more--><\/p>\n<div class=\"answer\">\n<p class=\"Body\">You can usually pick up Murphy gauges from large automotive stores. Also, they used to be carried by McMaster Carr in their catalog. Re: props, you are quite right about prop blade twist. Paul Luke&#8217;s phone is 207-633-4971, and their web site is www.peluke.com. Also, you may want to check out the Autoprop, about which we&#8217;ve heard positive things. <\/p>\n<p class=\"Body\" align=\"center\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>I very much enjoyed your Encyclopedias, Volumes 1 and 2&#8230;Do you have an address for the manufacturer of the Paul <a class=\"read-more\" href=\"https:\/\/setsail.com\/luke-propellers-murphy-gauges\/\">&#8230;Read More<\/a><\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[10,15],"tags":[],"class_list":["post-1265","post","type-post","status-publish","format-standard","hentry","category-tech-talk","category-yacht-propellor-faqs"],"_links":{"self":[{"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/posts\/1265"}],"collection":[{"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/comments?post=1265"}],"version-history":[{"count":1,"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/posts\/1265\/revisions"}],"predecessor-version":[{"id":36388,"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/posts\/1265\/revisions\/36388"}],"wp:attachment":[{"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/media?parent=1265"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/categories?post=1265"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/tags?post=1265"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
