   Technical drawings of Hanse keels are on:
 https://hanse.boatoon.com/en/search?order=score&p=1&search=keel
 - but you will only find the keels in stock by boatoon. If you need a special drawing, email boatoon for it.
The drawing above is for a Hanse 370 year 2006, where the total weight of the keel is 2188 kg, and the draught 1,95 meters. My H400 (2006) has a 10% longer mast (19,52m) and a 1,98 meter heavier steel/lead keel with a total weight of 2915 kg.
The iron part of the keel on my 400 is fastened to the hull with 10 pieces of 42mm bolts in galvanized steel which is stronger than stainless steel. The H370 (see drawing) has bolts in 42/36/24mm since the keel is 727 kg lighter. Be aware, that the double bolts are not apparent in the H370 drawing, since no top view is shown.

	Pity the boatoon site does not have the similar diagrams for the vintages around 2007 400's etal. But I expect it is similar to the 370 as mine is experiencing similar rust and cracking points!

	Yes, the 400 keel is very similar in construction to the 370. I have a 400e in Sydney too, and it needed a lot of TLC a few years ago.
