Sneakeasy is a 26 foot phil bolger "power sharpie", a simple flat-bottomed craft (at least in it’s initial conception), which phil advances as a very efficient power boat, but which also retains essential elements of the period elegance of some early 20th century speedboats.. In the 1970s, phil bolger began a long and successful collaboration with harold ‘dynamite’ payson with bolger designing the boats and payson building them as well as selling plans and writing books about how to do it. ‘dynamite’ called the first series of easy-to-build plywood boats "instant boats"..
