Very true, but unlike armour piercing bombs where a miss is as good as a mile, earthquakes all around are a debilitating experience. Although the ground was soft mud and this may have absorbed energy. Apparently a loading of 6 by 2000lb AP bombs was considered but earthquake effect was thought worthwhile.and the Lancasters were targetting the battleship, not the anchorage point.
The 2006 very reliable version of Antonio Bonomi posted a map showing 4 more Tallbuoy impacts inside the net barrage but there are many huge misses, even 617 squadron (and friends) weren't perfect. The smoke screen was late but seems to have affected some bombing.
He also said of the earlier KaaFjord LongStraumsneset attack (copyright Antonio Bonomi 2006)
No armour on the bow.The bomb passed all the way thru the decks like on butter, and exploded on the bottom of KaaFjord, lifting up the whole ship forward.
The bow was totally smashed below water level on the starboard side as photos well shows, juts like a twisted can.
Tirpitz was not able than to sail at more than 8-10 knots, due to water pressure on forward compartments.
All the best
