I was curious about the actual 'Hull Depth" measurement because when I applied for documentation I was told to use the distance from the inside of the cabin top to the cabin sole. The tonnage calculated by USCG is a measure of interior volume available for cargo not weight, after all.
Here are the USCG instructions from the measurement form: DEPTH (D) is the vertical distance taken at or near amidships from a line drawn horizontally through the uppermost edges of the skin (outside planking or plating) at the sides of the hull (excluding the cap rail, trunks, cabins and deckhouses, and deck caps) to the outboard face of the bottom skin of the hull, excluding the keel. If your vessel is designed for sailing and the interface between the "keel" and the "bottom skin of the hull" is not at a clearly defined location (as is the case with an "integral" or "faired" keel), include the keel in the depth measurement. -----Original Message----- From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Bill Bina Sent: Tuesday, April 23, 2013 5:50 AM To: cnc-list@cnc-list.com Subject: Re: Stus-List sailboatlistings.com Inaccurate Listing for a 33-1 The hull depth measurement for documetation purposes is not the same as the draft. The hull depth on my C&C 27 is 6.8 feet, and it's draft is about 5 feet. I think the design draft for my boat is stated as 4 feet 11 inches. Draft is the length below the water line when the boat is floating. Hull Depth is measured from the toerail down to the bottom of the fixed keel. _______________________________________________ This List is provided by the C&C Photo Album <http://www.cncphotoalbum.com> http://www.cncphotoalbum.com <mailto:CnC-List@cnc-list.com> CnC-List@cnc-list.com
