I'd have loved to do this one, Chris, in spite of the restrictions (tide, traffic and traffic wardens!) but I'm committed elsewhere....
Remember that anchorage No.8 isn't very far from shore AND the main traffic lane through the Solent. There's a lot of traffic scheduled at the times proposed (some -politically?- interesting -"Anvil Point" *, is off to the Falklands) but several large incoming (and some outgoing) boats with rolling exclusion zones around them.
This, combined with an exclusion zone of 150m aroung the 333m long Roosevelt, and 1 to 2 knot tide flowing at ca 290 deg. will make a circumnavigation difficult without upsetting someone...especially on the south side of the Carrier.
Extract from QH Portsmouth Notices to Mariners:
<<Police craft will be in attendance with the vessel to enforce the requirements of this Local Notice to Mariners [ LNTM 31/15 ]. They will be clearly identifiable and will be acting on the authority of the Queen’s Harbour Master. All vessels are to comply with their instructions. In accordance with General Direction 02/15 (Keep Clear of Warship Alongside or at Anchor) exceptionally for this vessel, a 150 metres exclusion zone is designated while the vessel is at anchor in the Solent and will be enforced. >>
