SailPlanner Pomerania | GammaSoft: Custom Software Development Company

Connecting sailors with their next port of call

We built SailPlanner Pomerania for the association behind the West Pomeranian Sailing Route. The mobile app combines route planning, berth requests and local information, helping sailors explore West Pomerania and neighbouring German waters.

What we delivered?

We brought practical harbour information into voyage planning. Sailors can compare marinas by their facilities and suitability for their boat, then request a berth before arrival. Routes and weather forecasts appear on the same map, helping them assess the next leg of the trip. Local attractions and events give them reasons to spend time ashore.

We gave marina teams direct control over the information behind those plans. A shared web panel helps them keep harbour information current and coordinate incoming visits, from berth requests to confirmed assignments. Staff can send notices to sailors who have booked a stay or follow a particular sailing area. Content in Polish, English and German makes local information accessible to visitors from both sides of the border.

Technology stack

A Java/Spring Boot backend with PostgreSQL and PostGIS serves the mobile apps and marina panel. The Android and iOS apps use Kotlin Multiplatform and Compose Multiplatform; the web interface uses React, TypeScript and Next.js. MapLibre and OpenLayers provide maps, while Firebase Cloud Messaging delivers updates to sailors’ phones.

What problem we solved?

Every stop on a sailing trip has to work for the boat and the people on board. That means knowing the marina’s approach depths and facilities, assessing conditions and arranging a place to moor. For the client, the challenge was to make this information usable across a network of Polish and German ports, while giving each marina a practical way to keep it current and respond to visiting sailors.
