Weems & Plath 176 Ultralight Marine Divider – Precision Navigation Tool

Overview

Meet the WEEMS & PLATH 176 Ultralight Divider, a practical addition to any navigation kit. Its compact 7 inch length fits neatly beside charts or aboard a vessel, and the lightweight design helps reduce fatigue during extended plotting sessions. This divider is built to endure the demands of daily use while maintaining precise, repeatable performance.

Durable construction you can rely on

The divider is crafted from coated marine alloy with plastic components to resist corrosion from salt air and splashes. The feel in the hand is solid yet smooth as the arms move, and the center axis stays steady, delivering reliable measurements even with frequent adjustments.

One hand, precise control

The center adjustment mechanism lets you lock in a span with a single motion. This enables quick, accurate transfers of distances on charts without repositioning your grip, which is especially helpful when space is limited or you wear gloves.

Versatility in a single tool

• 7 inches (17.78 cm) long
• Coated marine alloy and plastic construction to resist corrosion
• Includes spare points, knob, wheel, and lead
• Made in Germany
• Limited Lifetime Warranty

Another aspect of its versatility is the possibility to swap the stainless steel points for pencil leads, turning the divider into a drafting aid for chart work. Interchanging tips also allows a compass-like function for basic orientation tasks, expanding its usefulness on the fly. The balance between light weight and rigidity supports precise radii transfer and careful marking on paper maps and nautical charts.

Real world use cases

Use it at a chart table during calm conditions or aboard a vessel where space and hands are at a premium. The one handed operation frees your other hand for a pen, a light, or turning a page. Spare parts ensure you can maintain consistency over time and adapt to small field tweaks.
