About
Trimlog is a purpose-built sailing analytics app designed for competitive and performance sailors who want to maximize their on-water results. Developed by sailors with over 10 years of racing experience, Trimlog digitizes the classic trim diary — replacing pen-and-paper notes with structured, searchable data you can actually learn from. At its core, Trimlog lets you log detailed boat trim settings after each session, record GPS-tracked training sails, and review your performance through graphs and statistics. Before you head out on the water, the app surfaces personalized trim recommendations tailored to the current weather conditions, so you spend less time in trial-and-error mode and more time sailing fast. The platform supports multiple boats and offers ready-made templates for popular boat classes, making it easy to compare settings with sailing partners or training group members. A cloud sync feature keeps all your data accessible across devices and sharable with coaches. Key features include: GPS sailing session tracking, trim data entry with class-specific templates, performance analytics and graphs, weather-aware trim recommendations, a built-in to-do list for boat preparation, multi-boat management, and Trimlog Cloud for data storage and sharing. Trimlog is ideal for club racers, competitive dinghy and keelboat sailors, sailing coaches, and regatta teams who want to build a structured, evidence-based approach to boat tuning and training analysis.
Key Features
- GPS Sailing Session Tracking: Record your sailing training sessions with GPS tracking to capture speed, route, and performance data over time.
- Digital Trim Diary: Log detailed boat trim settings using structured templates for popular boat classes, replacing disorganized pen-and-paper notes.
- Performance Analytics & Graphs: Visualize trim and training data through charts and statistics to identify patterns and benchmark progress across sessions.

Use Cases
- A competitive dinghy sailor logs trim settings after every training session and reviews graphs before a regatta to find the fastest settings for upcoming wind conditions.
- A sailing coach shares a Trimlog group with their athletes to compare trim data across the fleet and identify which settings are producing the best boat speed.
- A keelboat racer uses the GPS tracking feature to analyze speed and route data from practice races and identify areas for tactical improvement.
- A sailor managing two different boat classes uses Trimlog's multi-boat feature to keep separate trim diaries and templates for each, avoiding confusion between setups.
- A regatta team uses weather-dependent trim recommendations the morning of a race to quickly configure their boat for the forecasted wind range without extensive on-water testing.
Pros
- Built by Sailors, for Sailors: Developed by performance sailors with 10+ years of racing experience, ensuring the app addresses real-world needs on the water.
- Proactive Recommendations: Weather-aware trim suggestions before each session help sailors start tuned correctly and save time during training.
- Structured Data Over Chaos: Organizes trim and performance data in a way that is actually useful for analysis, unlike unstructured handwritten notes.
- Multi-language Support: Available in 16+ languages, making it accessible to sailing communities across Europe, Asia, and beyond.
Cons
- Niche Use Case: Highly specialized for sailing; not useful outside of the sailing/watersports context.
- Community Size: As a startup tool, the user base and template library may be smaller than established sailing software, limiting class-specific comparisons.
- Dependent on Consistent Data Entry: The quality of analytics and recommendations improves only with regular, detailed trim logging — requiring discipline from users.
