Accurate Chart Plotting – thanks to Portland-style course plotter
Portland-style course plotters present common chart scales on a transparent acrylic body, with clear scale graduations in contrasting red and black. The transparent base keeps chart details visible while aligning bearings precisely against latitude and longitude lines.
Consistent, repeatable plotting reduces navigational error and speeds up route planning. Professionals and students benefit from quicker, more confident chart work.
