Thanks Zonker! It took me two trials after screwing up on the cube of his displacement AND using fresh water instead of salt water, but I ended up with 13.03 in the end too!( I should have also ignored the blasted decimal points).

Thus, if we toss in the incredible wind drag from his rigging set up, this boat is well into slug territory and will require reliably(read: always) using his engine to get anywhere except downwind. I see big diesel bills in his FUTURE if he ever decides to actually travel anywhere.

As for Duggs inspirational quote, I suppose there can be a little tourista in all of us, given the proper conditions :D
What's this future you allude to ???

You and Zonker appear to have used roughly 70.5 tons for displacement. I took a crack at weight just now since my SA/D was lower, thought I'd doublecheck. Many items were added after the thing was weighed on the hard. I didn't add anything for exhaust pipes, various angle iron frames, benches, heads etc., but I filled the stated capacities of water and diesel. Here is the tally:
SV Seeker weight calculation

Port Keel 50920
Starboard Keel 53147
Aft Keel 7001
added after weighing:
Rudder 1000
TX Allison 545 267
Cummins 5.9 6BT 975
Hundestadt 50 est
Prop shaft 150 est
Propeller 200 est
Vmac 45cfm, 8kw, 8gpm 575
Scuba compressor 275
Main Mast +sails 2000 Captain est.
2 other mast + sails 2000 Captain est.
Batteries 1000 est
Fuel diesel 8400 4 x 300 gal tanks 7lb/gal
Crane 1000 Captain est.
Tender Whaley + 50 yam 853 606+247
water 4998 2x300 gal 8.33lb/gal
People, supplies, fridge etc 8000 per his video est
watermaker 250 est
milling machine 800 Captain est.
extra lead ballast for trim 2000
Miller 130 welder 70
Cargo for researchers 0
misc fittings and pipe 0
ropes 200
Total 146131 lb. 73.1 tons

It appeared in that weight determination video the aft cabin had just been painted; it and the engine room looked pretty empty, so going heavy on water and diesel estimate should not be too much of an overestimate. There is a lot of plumbing, wiring and connection boxes and trays not cited, plus aft flooring and cedar planks.

Yup, I went with an even 70 ton but am impressed with your accounting of the amount of junk/stuff which Dugg has added afterward.It never occurred to me it could be that much shit. I'm curious about the ton and a bit difference between the two bilge keels. Is this something Dugg actually calculated and broadcast?

Doing a weight estimate on the BST is a waste of time. Any guess would be purely a guess, not even an educated guess. Wiring and piping on a boat this size weighs a lot more than you think. Even paint can weigh a tonne or more.

He rented a special hydraulic cylinder of known area and bought a large calibrated oil filled gauge then lifted it at 3 points when partially complete. That effort produced the first 3 numbers comprising 55.5 tons. He had a contest going for viewers to guess it's weight at that time and gave a prize. So yeah the list propensity showed up before launch. If nothing else perhaps a minimum weight falls out of my calc. His displacement on AIS now appears as 40 tons for some reason. He did a video of that weight and waterline determination. Somebody did a 3D model of the hull from his shape measurements to calc his waterline which was painted higher than actual expected. They did pretty good but missed the fore-aft cg position and forgot the list bias; just went straight up from keels.

Paint was mostly completed when it was weighed. Wiring and piping was not complete and I agree they add a lot. Is not the calc of SA/D itself a waste of time if neither number is reliable? Took 14 years for this turd to flush into the gulf, and it is still accumulating mass as a never ending parade of more small stuff marches up the gangway like valves, blocks, clamps, sail holder gadgets, propane heater, grille, tractor seat, rope, cleats, winch, icemaker, etc.

This link will timestamp to the relevant part.
The boat was bare bones and not outfitted at this point - just the shell. You'll see he's amazed at how heavy it became.At 55 tons.
