Anyway, the RN still has a hudge superiority over DKM and I cannot see how the German could prevent British warships to sink the invasion fleet.
... A simple way to cover the invasion force would be to send it by night, with first landings at first light.
Various decoys, false landings, false convoys, radar jamming, etc, would distort the British perception of the action, and dillute the strength of the naval attack.
Probably all operational Uboats and Torpedo boats would be redeployed in the Channell, and there were quite a few in late 1941... This along with the surface force which would have at the very least Tirpitz, Scharhorst, Gneisenau, Hipper, Lutzow, Prinz Eugen, Scheer, and 18 destroyers.
I would also expect massive heavy artillery planted on the shore line (280mm and more), with radar support, for covering fire.
A critical aspect would also be exactly how many units could Britain concentrate to fend off an invasion. Protecting the shipping lanes and keeping Mediteranean were essential, and the need to provide some forces in the far east was important also.
Some ships would be in repair/refits, and thus only a fraction of the total assets of the Fleet would be available, on a moment's notice, to sortie and engage the enemy.
(historical Dec 1941 for example has Prince of Wales, Repulse (assuming they wouldn't be sent to Singapore), KGV, Rodney, Duke of York (shakedown), Renown, Revenge, Malaya, Royal Sovereign were the available capital ships . Carriers: Eagle, Victorious. Considerable number of smaller ships (at least 30 cruisers and 100 DDs operational) )
