!st Post - Neutral ports

[Ottensen]

Ahoy ahoy, I've been meaning to register on here for about 18 months now but a failed search on this subject has finally forced my hand.
I know, I should have joined a lot earlier.

Playing GWX1.3, 1941, out of L'Orient in a IX/B, I've often visited Porta Delgada in the Azores if I've enough diesel left over. Every time so far (April-July 1941) there's been the same vessels, about 10 Portuguese of various sizes, a Brazilian merchant and 2 British - a modern medium tanker and a small merchant. The usual form is , I sink the British vessels with no resistance from anyone. Easy renown points so I thought.

Having scored just 670.73 on my last excursion for the aforementioned 2 ships and an Anson, patrolling the assigned zone for 24 hours and returning to base - on 57% realism - I wonder - Is sinking the British ships regarded as negative renown due to them being in a neutral port?
