Hi
just wondering if you can give me some feedback on my DR position for the above question.

Lat & Long 0337 DR estimated position 48 21.5 123 21.5
Hopefully I'm not too far off the mark!

Can you advise about calculating 7 leeway

many thanks
Steve

Your DR position is correct.
7deg leeway simply means that the wind is pushing your vessel 7 deg off your intended course in the direction that the wind is blowing.

For example on the first leg your intended course is 305 M or (for plotting) 325 T. With the wind blowing over your port side it is pushing your vessel to starboard thus your course would be 325 T plus 7 deg = 332 T. Apply the same logic to the other legs. Remember when you tack the wind will be over your starboard side thus you subtract the 7 deg leeway.
