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
- Yes
- 2.6m
- No
