The portland course plotter from Blundell Harling is an essential kit for students taking training courses and for seaman. This kit includes 7" dividers with a brass finish and a fixed grid base. This is the most popular choice for chart work as it offers accuracy and strength, this kit is widely used by RYA instructors both practical and shore based.

The item came well protected. I use triangles so I purchased this to test it and see if there are benefits. I do not like divider, it can not be spread wide so I will not suggest anybody to order this set but rather plotter with straight divider combo. It looks nice, but low practical value. Plotter is perfect.
