505 Sailing Dinghy

If you are an administrator for the 505 UK Class Assocation please use this CLASS ASSOCIATION data collection form to provide more details. We want this page to represent the boat you love to sail. We hope to add more information from the UK 505 CLASS ASSOCIATION shortly. Thank you for helping make Dinghy Mart a website created by sailors for sailors

The 505 is a double handed performance sailing dinghy with a traditional spinnaker and a single trapeze for the crew. Incorportating a light weight, high performance hull design with a powerful sail plan and one trapeze for the crew. A unique boat which responds well in all conditions. In light winds it is quick and responsive – planing at just 10 knots. When the breeze kicks in the 505 just keeps going faster.

If you can't find one here... try eBay

It might not be the first place that springs to mind when buying or selling a dinghy - but it's definitely worth looking. We've found some great boats on eBay. My last Topper Topaz Race X came from eBay and it was £400 cheaper than similar elsewhere. Click the banner below to browse the latest listings. People sometimes don't know precisely what it is they're selling ... try a few searches using different phrases. Start with the obvious - CLASS - eg. Laser or Topper or SuperNova etc.
