Chart Weight IMPA 371021-371023 — Stainless Steel Chart Weights for Ship Navigation

Chart weights are essential navigation aids used on the chart table of cargo ships, container vessels, tankers, offshore supply vessels and other commercial craft. They hold paper charts flat and prevent them from shifting or curling during route planning and position plotting, especially in heavy weather or when the vessel is rolling. Available in three weights — 550 g, 930 g and 1,300 g — these stainless steel weights keep charts secure without damaging the paper, making them a practical addition to any bridge or chart room.

Each chart weight features a solid stainless steel body with a soft cloth-lined base that grips the chart surface without scratching or tearing paper. The round shape allows easy pick-up and repositioning, while the substantial mass holds charts firmly in place. Stainless steel construction resists corrosion in the humid, salt-laden atmosphere typical of marine environments, ensuring long service life on board. The full range covers IMPA codes 371021, 371022 and 371023 (3 variants total), each available for individual order to suit different chart sizes and conditions.
