I don’t know, Chuck.
Back when I shortened the keel and added a torpedo bulb to Imzadi in 2003, we measured the draft as 5’3”, before she was launched. The bulb was something like 350 pounds more than the weight of led removed when we cut off the keel, so the floating draft might be a skoosh more than 5’3”. About 2011 I raised the waterline by 3” and I still get crud growing along the edge of the bottom paint. Measured between 5’6” and 5’7” during a short haul to clean the bottom last summer. Which means I’ve added something like 4300 pounds of cruising crap like anchors, chain rode, radar, batteries, windlass, cabinets, etc. Maybe it’s a good thing I only enter in party class or cruiser class on those occasions when I race her. Wonder if I could get a PHRF adjustment because of the extra weight and wetted surface?

I use a tape measure or folding rule and a laser level. I use the watermark waterline on the boat's bottom paint. I set a 2 x 4 against the side of the boat. Then use a laser level or a string level, to bring the bottom of the keel out to mark the board, and the waterline to mark the board, and you measure the difference to get the real draft. I found many of the designer stats were bogus. I measured three 4' 10" draft boats that actually draw 5' 3" or more. A 5" difference would suggest 5000# of gear aboard. More likely the stats posted were scewed to sell more boats.

I went back to Sailboatdata and there it was, the very last line at the bottom of the page, shoal keel 4 ft 2. The owner says he thinks it's the deep keel, but doesn't think it's as deep as 5 ft. Not sure where 4 ft 7 comes from. What is the proper way to measure keel depth? Is it waterline to bottom of keel? Thanks again. _______________________________________________ Email address: CnC-List@cnc-list.com <mailto:CnC-List@cnc-list.com> To change your list preferences, including unsubscribing -- go to the bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com
