How did you get on with last weeks question?

Here is my answer - thank you to getlostpowerboattraining.com for the use of their very useful bridge clearance worksheet. 

Using % rule or rule of 12th’s at 1220 HoT will be 8.3m

 

E - F   =  2.5m safety of 2m =  0.5 m

 

Barometric pressure is 1023 giving an extra 1023 - 1013 = 10cm clearance 

Total clearance including safety = 2.6m

 

Answer 

  1. Yes
  2. 2.6m
  3. No
