Plastimo Offshore 105 Compass Zone C for 5-9 m Powerboats Flat Card Navigation Precision

Plastimo Offshore 105 Compass – Zone C is a purpose-built navigation instrument for powerboats in the 5–9 m (16–29 ft) range. The 91 mm flat-card design delivers crisp, stable bearings with 5° graduations and heading numerals every 30°, providing rapid, confident readings whether you’re cruising at speed or negotiating choppy seas. This is the Zone C variant, tailored for regions covered by that specification.

Designed for recessed panel installation or steering-area mounting, the Offshore 105 fits a 100 mm cutout with a 140 mm flange footprint and a compact profile of 92 mm above surface and 42 mm below the dash. Its flush-mount configuration keeps the console smooth and uncluttered, while the optional bracket kit (OFF105BRKT) offers versatile mounting if your layout requires it.

Readability comes first in all lighting conditions thanks to the built-in 12 V lighting and the articulated sun hood—a three-part, sliding cover that you can position to minimize glare as daylight shifts. Whether you’re in bright sun or twilight, the dome stays legible without reflections, and you can secure the hood when docking or at anchor.

Engineered for real-world seakeeping, the Offshore 105 features a vibration-absorber system that maintains card stability under hull pounding and at speed. Alongside the robust waterproof diaphragm and scratch-resistant dome, this design keeps the bearing information accurate when conditions get rough, so you can steer with confidence even in demanding conditions.

Armor for reliability and safety comes standard with SOLAS and EC 96/98 compliance, ensuring the instrument meets recognized marine safety and regulation benchmarks. The Offshore 105 is built to endure marine exposure, with UV-resistant materials and sealed internals designed to resist weathering and fuel or spray exposure while delivering consistent performance.
