Teaching Theory at Powerboat Level 2

Understands: Charts, Chart Symbols, Buoyage Systems


  • Chart Name / Area
  • Year of print (i.e. is it current enough?)
  • Colours
  • Depth (Chart Datum)
  • Scale
  • Symbols (Hazards, Buoyage, Compass Rose Useful items: Fuel, Toilets, Slipways etc)
  • Latitude & Longitude Lines
  • Land Marks

Check Understanding: Q&A session

Understands: Tidal Heights & Tidal Streams:


  • Where to find tidal information (EasyTide, Internet, Almanac, Tide Table)
  • How to understand the above
  • Springs and Neaps - why do we need to know that they occur and how it effects us. 
  • Relevance to us: Slipways/launching, Anchoring, Depth, Sea Conditions (Wind with and Wind Against Tide), Safety
  • Tidal Streams: 'Show' your students a visual representation (i.e. on a buoy)
  • DO NOT TEACH: 'how tides occur' nor tidal curves, nor tidal diamonds, nor Rule of 12th.. (if they want to learn more - suggest the RYA Essential Navigation & Seamanship Course. 

Understands: Pilotage & Passage Planning:


  • Measuring distance on a chart
  • Taking a bearing from a chart (+ Variation)
  • Speed / Time / Distance
  • Where to get local information: Internet, Local area 'boating guide', Almanac
  • Create a simple pilotage / passage plan as a group
  • Ensure your students understand the 'requirement' to have a plan (SOLAS V regs)
  • Considerations: Depth, Weather, Local Regulations, Local Hazards, RYA SafeTrx, Shore Contact

Can: Use steering and hand bearing compass:

Cover (Afloat): 

  • Steering to a heading (helm compass)
  • Take a 3-point fix using a hand bearing compass
  • Illustrate Deviation
  • Ensure all students participate / have a go..
