How Do I Choose the Right Size Bimini Top for My Boat?

To pick the right bimini top you need a few measurements:

graphic showing how to measure a bimini top

Width: Measure the distance between the mounting points on either side of the boat. This will determine the width of the bimini top you need.

Height: While standing in your boat, measure up from your desired mounting point on the side of the boat to how high you want the overhead canopy to sit. Make sure to account for how much head clearance you need to get in and out of the drivers seat while the top is up.

Length: You also need to consider how much coverage you need front to back to make sure all the seats you want to be shaded will be covered with the top up. Measure from the furthest forward part of the boat that you want covered to the farthest back and match the length of your bimini top as close to that measurement as possible.

Types of Bimini Tops

4-Bow Square Tube Pontoon Bimini Complete Top Kit

Pontoon boat bimini tops like this one usually feature square tubing to match the fence railing on the boat.

Bimini tops are available in a variety of widths and lengths to fit the needs of your boat. Pontoon boat bimini tops are generally on the longer end to shade as many seats as possible and have square tubes to match the square tube fence railing on pontoon boats. For smaller ski boats, a 6', round tube should give you plenty of shade, but you should always measure to make sure.

How to Install a Bimini Top on Your Boat

Many boat bimini tops come packaged with the hardware you need to install it on your boat. Follow these step-by-instructions to get yours installed right

  1. Determine the mounting points and position the deck hinges on the gunnel of the boat. Measure to make sure that your deck hinges even on both sides of the boat.
  2. Clean and mask the mounting area with masking tape
  3. Use the deck hinge as a guide to mark the mounting location and screw holes
  4. Drill pilot holes using the appropriate size drill bit for the screws in your kit
  5. If you’re mounting to fiberglass, make sure to counter sink the pilot hole or hollow it out slightly using a circular motion while drilling
  6. Apply marine-grade silicone to the pilot holes to prevent leaks before mounting the hinges using the provided screws
  7. Apply the same steps to mount the eye hooks for the straps

Quick Tip: When mounted properly, the straps and vertical support bars should resemble a wide “M” shape to ensure your top has enough tension on it to be supported properly

Adjusting the Hold Down Straps

The hold down straps need to be as tight as possible to work properly.

  1. Clip in all hold down straps and tighten them as much as you can
  2. Unclip each strap one at a time and tighten it another one to two inches
  3. It should now take a decent amount of force pulling on the strap to get it to reach the eye hook

Quick Tip: You can use your free hand to pull down on one of the vertical bars of the bimini top to give you the leverage you need to clip in the tie down straps
