Keel: Your Essential Boat Load Journal

Protect your investment and master your vessel's maintenance with precision tracking. Keel is a specialized technical diary designed for boat owners who want to understand the true impact of every voyage on their engine and hull. By logging real-world conditions instead of just hours, Keel provides a deep look into your boat's wear and tear, making it perfect for vintage vessels or high-performance crafts.

Log Trips, Not Just Hours
Move beyond simple hour meters and record the factors that actually affect your boat's longevity:

Voyage Details: Record the exact date, time, and duration of your trip (from 0.25 to 24 hours).

Crew & Cargo Tracking: Log exactly how many people were on board and the total weight of your cargo in kilograms.

Wave Level Analysis: Categorize sea conditions using a 6-point scale, ranging from 0 - Calm and 1 - Ripple to 5 - Severe.

Performance Metrics: Optionally track your average speed in knots to refine your wear calculations.

Professional Wear Insights
Keel crunches the numbers for you, transforming raw trip data into actionable maintenance intelligence:

Total Load Score (TLS): Every trip is assigned a TLS based on intensity factors like crew size, wave height, and speed.

Engine vs. Hull Wear: Track cumulative wear points separately for your engine and hull to see which needs attention first.

Trip Intensity Ratings: The app automatically rates your runs as Light, Moderate, Heavy, or Harsh.

Quiet Hints: Receive silent visual cues and maintenance tips, such as "Heavy load – check engine oil sooner than usual," without annoying alarms.

Analyze Your Nautical History
Visual Progress Charts: Review your TLS Per Day and Cumulative Wear over 7, 14, or 30 days with professional line and bar graphs.

Trip History Log: Revisit a detailed archive of past runs, including specific notes about "Storm chases" or "Resupply trips."

Efficiency Statistics: Monitor your Total Hours Underway, Average TLS, and total number of trips at a glance.

Sleek Maritime Design: Enjoy a high-contrast, deep-sea aesthetic that makes your technical data easy to read in any lighting.
