The strakes are instrumental in creating a multitude of bubbles on which the hull of the boat will ride which increases the efficiency of the power of the motor or motors powering the boat. the strakes are arranged in series along the hull of the boat and can increase in size from the bow of the boat to the stern.. This spring i acquired a 20 foot aluminum riverboat, and have some questions and concerns about the hull design. the boat is actually 19’-8” with a 60” wide bottom, outboard jet powered with a forward walk thru windshield, very similar to a wooldridge extra-plus.. Z strake from stingrayquote: .in a nutshell, the z-plane hull design essentially incorporates the hull strakes into the bottom, rather than having them appear as external appendages that have been added on after the hull surface was completed..
Hull and frames design for 'hogging' introduction. usually there is no construction drawing available for old wooden boats. to still be able to get a line plan of the hull and frames down on paper the main dimensions of the boat have to be obtained, even if the boat is usually weakened and deformed.. Hull design variations & traits “deep “v” hulls: smaller, lighter performance hulls typically use a 22 degree deadrise hull with “step” shaped strakes that are conducive to good lift and hull aeration, while providing predictable tracking and grip when cornering.. Lifting strakes can be specified for tunnel hull or vee hull configurations. tbdp©/vbdp© accounts for the use of lifting strakes in your hull design. select use of lift strakes by making selection of the drop-down box on input screen #4, selecting “one strake”, “two strakes”, “three strakes” or “no strakes”..
