Buying a bimini top can feel daunting. Getting the wrong size means ineffective sun protection, poor fit, and ultimately, wasted money. This comprehensive guide will walk you through accurately measuring your boat for a perfect-fitting bimini top. Accurate measurements are crucial for a custom or ready-made bimini that provides optimal shade and protection.
Understanding Bimini Top Measurements: Key Dimensions
Before you start measuring, gather your tools: a tape measure (preferably a flexible one), a pen, and paper. Understanding the key measurements will make the process smoother. The most crucial measurements are:
-
Boat Width: This is the widest point of your boat's deck where you want the bimini to sit. Measure from the outside edge of one gunwale to the outside edge of the other. Remember to account for any existing railings or other obstructions.
-
Bimini Length (Front to Back): This is the distance from the front mounting point to the rear mounting point. Determine where you want the bimini's front and rear to be positioned on your boat. This will usually be just behind the helm or windscreen and towards the back of the seating area.
-
Height (from Deck to Top): Decide how much headroom you require under your bimini top. Measure from the boat's deck to your desired height.
-
Frame Style: Consider your desired frame style; single-bow, double-bow, or another variation. The shape influences measurements but isn't a direct measurement itself. This will be addressed later.
Addressing Challenging Boat Shapes:
Not all boats are simple rectangles. Many have curved decks, angled gunwales, or other features.
-
Curved Decks: For curved decks, take multiple measurements at various points along the width. Note these down to communicate the curve to your bimini supplier. A simple average width is insufficient.
-
Angled Gunwales: Account for any angle in your gunwales. Instead of a straight line measurement, measure along the angle of the gunwale. A picture aids significantly here.
-
Unusual Shapes: If your boat has unique features, take lots of measurements and photos from different angles. Clearly indicate any unusual angles or curves.
Step-by-Step Measurement Process:
-
Identify Mounting Points: Decide where you want the bimini's front and rear supports to attach to your boat. These points are vital for determining the bimini's length and overall structure.
-
Measure the Boat Width: Measure the widest part of your boat at the mounting point, accounting for any curves or angles. Take several measurements at different points along this width to capture the shape's nuances.
-
Measure the Bimini Length (Front to Back): Measure the distance from your chosen front mounting point to your chosen rear mounting point along the boat's centerline. This measurement might need adjustment depending on your frame style and desired overhang.
-
Measure the Desired Height: Measure from your boat's deck to the desired height of the bimini top. Consider factors such as your height and the desired amount of headroom underneath.
-
Document Everything: Write down all your measurements clearly and label them (e.g., “Boat Width 1: 7ft”, “Boat Width 2: 7.2ft”, “Bimini Length: 6ft,” "Height: 5ft"). Take multiple photographs of your boat, especially focusing on your chosen mounting points, the curve of your deck, and any other features that might impact the fit. This comprehensive documentation will be invaluable to your bimini supplier.
Choosing the Right Bimini Top Frame:
Your frame choice affects the overall dimensions. A single bow will have a different shape and therefore different spatial requirements than a double bow.
- Single Bow Bimini: Requires less overall length.
- Double Bow Bimini: Offers more headroom and stability but typically requires a slightly longer measurement from front to back.
Consult with the supplier or manufacturer to confirm how the frame style influences the measurements you have taken.
Contacting a Supplier with your Measurements:
Once you have all your measurements and photos, contact your chosen bimini top supplier. Providing them with this comprehensive information will allow them to create or supply a bimini top that fits your boat perfectly. Remember, clear communication is key to achieving the ideal result.
By following these steps, you can confidently measure your boat and ensure that you receive a perfectly fitting bimini top. Remember to always double-check your measurements and contact your supplier if you have any doubts. A custom-fit bimini top will significantly enhance your boating experience.
