First off thanks to everyone for the answering questions in my other posts. I am a potential new owner of a 2015 so379 and the feed back is helpful. I got the survey report back and a number jumped out at me. The boat yard travel scale read 19000lbs for the boat. Jeanneau’ s listed displacement for the std deep keel version is 14771. Granted the aft water tank was full and the fuel gauge read 1/2 full. The forward water tank approx 1/2. Approx 250lbs for anchor rode. Current owner changed the house bank to 4 6v golf cart style batteries approx 300lbs. Main Genoa and spin. Other than that the boat was empty of gear and provisions. All total this adds approx 1600lbs. That seems to be a big discrepancy over 3500lbs. If the the travel scale is accurate it put the boat 200lbs shy of jeanneau’s maximum recommend total load which includes gear, and a crew of 8. Am I missing something? Are boat yard travel scales wildly inaccurate? Is it no big deal?

Hi Kankan, I can’t speak for other yards, but when I asked my yard to record the weight of my boat as it was on the scales, they told me aa figure. About 14 tonnes, I should be under four! When I queried it, they said not to worry, the crane was good for forty tons.
I would suggest that that you take the reading with a grain of salt, or more like a whole handful. But worth asking someone in authority about the accuracy of the scale. If they weigh race boats for rating purposes, they may have a better calibration.
Tank contents, batteries, and gear can add up quite quickly, so always worth keeping an eye on what is on board that you don’t really need, and making an effort to lighten the load if you ever race, but otherwise I would expect the specs to be within reasonable tolerance, and the scale a red herring until demonstrated otherwise.
Where are you located, and what sort of sailing do you plan on doing?

As I understand it, NO race rule agency will allow the reading from a hoist. You have to weight the hoist, then weigh both, then you have the accurate weight of the boat. It also has to be what most would call empty! ie no kitchen supplies, first aid kits, fenders, bathroom items, cleaning supplies etc. Just a base boat, with cushions, mast, and maybe sails........ Even at this, the hoist scale is not really that accurate, as they do not have someone calibrating them on a regular basis. If you trailered your boat, could get and accurate weight of the tow rig, trailer, then all together, you would be pretty close...... The hoist weight is a good ball park, plus or minus a ton or two!
