Definition of a semi-v hull

[Dr Ken]

Does anyone know of a website that gives the precise defintions of boat hull configurations? Or, does anyone know this offhand?<br /><br />The defintion of a v-hull is pretty self explanatory, but a thorough internet search could not come up with a definition of a semi-v hull.

13 degrees or less is considered "shallow" or "semi-V". <br /><br />14 to 17 degrees is "modified V" <br /><br />18 and up is "deep V".<br /><br />Or so I've been told...

The above measurements, are at the stern of the boat.<br /><br />The shape of the front of the hull doesn't matter.

Dr Ken,<br /><br />According to Chapman Piloting, 61st edition, "Hulls with deadrise angles (measured a the stern) of 16 to 19 degrees . . . are considered to be modified-V types, while steeper angles as high as 23 degrees are deep-V types."<br /><br />tcube

Re: Definition of a semi-v hull

Thanks guys. Groups like this can be a goldmine of information. I spent about an hour on various internet search engines and never got this information.<br /><br />I needed to know this because I was filling out a Capacity Plate application form that asked for hull conformation.<br /><br />Thanks again, Ken
