PortaBote Bimini Adapter for 1.5" PVC Pipe

This adapter is designed to let you install a standard Bimini top on a PortaBote without drilling into the boat. It uses a short section of 1-1/2" PVC pipe that slips snugly over the existing PortaBote gunnels, creating a solid mounting point for a Bimini top bracket.

The adapter sits between the PVC pipe and the Bimini hardware, allowing the Bimini to be mounted securely while remaining fully removable.

Use Case

• PortaBote owners who want shade without permanent modifications
• Drill-free Bimini installations
• Easy removal for transport or storage
• Works great for fishing, cruising, or long sunny days on the water

Required Parts

• Bimini top: 54"–60" width (recommended range)
• PVC pipe: 1-1/2" nominal diameter
  • Cut a short section, approximately 5 inches long
• Bimini mounting hardware (standard hardware included with most Bimini kits)

How It Works

1. Cut a ~5" section of 1-1/2" PVC pipe.
2. Remove only 20–30% of the pipe wall lengthwise so it can slide over the PortaBote gunnel.
3. Test fit:
   • It should be snug enough that it won’t easily fly off, but still removable by hand.
4. Slide the PVC onto the gunnel.
5. Place the printed adapter on top of the PVC pipe.
6. Install the Bimini mounting bracket on top of the adapter.

This creates a stacked system:
Gunnel → PVC pipe → Printed adapter → Bimini bracket

Hole Alignment

• Exact hole spacing is not critical
• If the holes don’t line up with your Bimini hardware, simply use a drill gun to make your own holes
• No need to match factory hole spacing

Notes

• Designed specifically for 1-1/2" PVC pipe
• Snug fit is important for safety and stability
• Fully reversible and non-permanent setup
• Ideal for users who want a clean, drill-free solution
