I see your point, although, you could also say the best defense is offense. Meaning, invading England will bring the action to their court and less likely an English invasion will occur. Giving you navy some rest is essential though, unless you like to take risks but given your previous post you rather play it safe. I'd say, once France is beaten down, place your navy in the western part of the Channel and start invading Cornwall and capture a port there. How many convoys and transports do you have?
I don't think I took any screenshots of the production queue so I loaded an old save and checked. As far as convoys went, in Late April, there were 71 convoys with 30 in the queue (with 30 escorts in the queue as well but 0 free/in use).
In terms of Naval build, there are two carriers in the queue to be complete in June and July and 2 escort carriers that will be complete next March and 4 light cruisers to be completed in August/september. For the army, there are 5 garrison divisions in the queue, ready in mid-june and a couple of Cav divisions ready in May.
