Club burgees starboard side.
Most senior club burgee above others if flying more than one (RNSA at top of course!).
If flying a blue ensign (can't as under 7m or 2 GRT
must get bigger boat) must also fly appropriate club burgee and have warrant on board.
Signal flags port side.
Ensign can go on centreline or starboard side but generally below burgees.
House flag (family crest etc.) can go at masthead above all others.
