how to measure a jon boat

2 min read 16-01-2025

Knowing the exact dimensions of your jon boat is crucial for various reasons: transporting it, finding a suitable cover, determining its capacity, and even for potential resale. This guide will walk you through accurately measuring your jon boat, covering everything from basic length and width to more nuanced measurements.

Tools You'll Need

Before you begin, gather these essential tools:

Measuring Tape: A long, flexible tape measure (at least 25 feet) is ideal. A standard 25-foot tape measure will suffice for most jon boats.
Pen and Paper: To record your measurements.
Assistant (Optional but Recommended): Having someone to help hold the tape measure can make the process much easier and more accurate.

Measuring the Length

The length of your jon boat is typically measured from the very tip of the bow (front) to the extreme end of the stern (back).

1. Find the Bow and Stern: Identify the furthest points of your boat, both front and back.

2. Extend the Tape Measure: Extend the tape measure from the tip of the bow to the furthest point of the stern. Ensure the tape measure is taut and follows the longest straight line along the boat's hull.

3. Record the Measurement: Note the measurement in feet and inches.

Measuring the Width (Beam)

The width, or beam, is the widest point of your jon boat, typically measured across the widest part of the hull.

1. Locate the Widest Point: Carefully examine your jon boat to find its widest part. This is usually near the middle of the boat.

2. Measure Across: Extend the measuring tape across the widest part of the hull, ensuring it’s perpendicular to the length.

3. Record the Measurement: Record this measurement in feet and inches.

Measuring the Depth

The depth of your jon boat is measured from the bottom of the hull to the top of the gunwale (the upper edge of the side of the boat).

1. Choose a Measurement Point: Measure the depth at multiple points along the boat's length—the bow, middle, and stern—to account for variations in hull design.

2. Measure Vertically: Place the tape measure at the bottom of the hull at your chosen point and extend it vertically to the top of the gunwale.

3. Record the Measurements: Record each measurement separately, noting where each measurement was taken (bow, middle, stern).

Other Important Measurements

Beyond the basics, consider measuring these elements for a complete picture:

Transom Height: Measure the height of the transom (the back of the boat where the motor is mounted). This is important for motor selection and compatibility.
Interior Length and Width: If you need precise interior dimensions for seating or cargo, measure the usable space inside the boat.

Tips for Accurate Measurement

Clear the Deck: Remove any obstructions on the boat's deck that could interfere with your measurements.
Take Multiple Measurements: Take multiple measurements at different points along the length and width to ensure accuracy, especially if the boat has a curved hull.
Use a Level Surface: Ideally, measure your boat on a flat, level surface for the most accurate results.
Double-Check Your Work: It's always a good idea to double-check your measurements to avoid errors.

Understanding Your Jon Boat's Measurements

Once you have all the measurements, you’ll have a detailed understanding of your jon boat’s dimensions. This information is critical for choosing the right accessories, transportation, and maintenance. Remember to keep a record of these measurements in a safe place for future reference.

By following these steps, you can accurately measure your jon boat and confidently use this information for various purposes. Remember accuracy is key, so take your time and double-check your measurements.
