Overview

The Garmin BlueChart g3 Vision HD VAF451S is an electronic chart region for the southwestern coast of Africa, covering waters from Cape Ponta-Grossa in Angola down to Knysna, South Africa. It includes detailed coverage for key areas such as Walvis Bay, Port Nolloth, Hondelklipbaais, and Cape Town, plus island groups including St. Helena, Tristan da Cunha, and Gough Island. Depth Range Shading supports up to 10 depth ranges, and detailed contours can show up to 1-foot intervals in supported areas.

This chart layer set adds spot soundings, depth contours, tides and currents, and detailed harbor and marina information so you can plan approaches and run familiar routes with more context. When your chartplotter supports the features, you can also use Auto Guidance for a suggested route and switch to MarinerEye and FishEye 3D views, satellite imagery overlays, and aerial photos for visual reference around ports and landmarks.

Variants

This chart region is offered in two delivery formats for compatible Garmin chartplotters.

The coverage area and chart code stay the same across the range, while the format changes how the chart is delivered and loaded onto an SD or microSD card.

• 010-C0751-00: Format microSD/SD. Preprogrammed card that installs by inserting it into the chartplotter card slot.
• 010-D0376-00: Format Download. Downloadable chart that is installed to an SD or microSD card using Garmin Express, with one chart per card during installation.

Compatibility and fit

This chart is for compatible Garmin chartplotters that support BlueChart g3 Vision and read mapping from an SD or microSD card. Features like 3D views, satellite imagery overlays, and Auto Guidance depend on the chartplotter model and its supported chart features.

Installation and setup

For the microSD/SD card format, insert the card into the chart slot and enable the map in the chart settings if your unit offers map selection. For the download format, install the chart to an SD or microSD card using Garmin Express and then insert the card into the chartplotter for use.

Use cases on board

This region is a practical match for skippers running coastal passages along Namibia and South Africa, as well as crews that want more depth and structure detail for fishing and anchoring decisions in the coverage area. It also helps when entering unfamiliar ports by pairing chart data with satellite imagery and aerial photos on compatible displays.
