Princess Augusta, late Augusta ; 1773
Type: Royal Yacht ; Armament 6 ?
Disposal date or year : 1818
Notes:

15 Nov 1803 the Princess Augusta, Hon Capt Grey, has dropped down the R Thames, with the yacht Royal Charlotte, Capt Sir H Neale, to take command of the frigates which have been fitted and manned under the direction of the Trinity Board, ie the Unite, 40 ; Modeste, 38 ; Heroine, 32 ; Solebay, 32 ; Daedalus, 32 ; Quebec, 32 ; Iris, 32 ; Retribution, 32 ; Vestal, 28 ; Resource, 28.

Circa 7 Jul 1804 the Euryalus, the Hon Capt Blackwood, is fitting at Portsmouth to attend his Majesty at Weymouth, with the royal yacht Royal Charlotte, and also the Royal Augusta, but I think that someone might have their wires crossed and that this should probably read Princess Augusta.
