Traveling East/West as you pass between Chase and Farm always stay North Side of Black Top Spar. The Marine stores and Gas Docks used to sell a decal you could place on the dashboard. Great Navigational tool in helping to understand course direction around markers. I learned acronym BReaking NEWS . B(black)R(red) Black Spar stay NORTH on East/West course; Stay EAST on North/South course; Red Spar stay SOUTH on East/West course; Stay WEST on North South Course. Maybe this will help. Also a compass is a good idea on any boat. If you don't follow these navigation rules you may be BREAKING NEWS on WMUR!!
