Beside trailer topic, that is very useful for everyday windsurfing, I have been thinking about something very useful but occasionally.One day as could design light but strong shipping box /container. Standard size that fit most gear needed.

For example 270 x 80 x 60 cm box.

Simple aluminium frame and lite skin made of aluminium sheet.

Now once in a year we want to organize trip to : Lake George, Burrum or Sandy Point for a sport event.

We could arrange truck to take all boxes on the way from Brisbane, Gold Coast, Sydney, Melbourne and deliver on site by LAKE GEORGE SA.
Then sailors could fly and rent a car or organize transport for themselves.

During the event all equipment could be safely storage in the boxes.
Worse case scenario you could even sleep in the box , better then in tent, only to turning on it side and opening cover/roof.Combining shipping for 30 our boxes on whole way Brisbane to LG shouldn't cost more then $100 pp if we have a good deal .

Well made box could last many years and even for everyday windsurfing - serve well with any box trailer or ute .

This way could save us building purpose made trailer and save on registration fee too.For discussion still remain generic standardized size that fit most of users, construction method , locks etc.
But the main reason for unification will be easy to transport, stack able design.

Having such agreed design we also could find a tradie that could build at lower cost 20 or 30 boxes.
I mean build the boxes here in Australia not Chinese knock off ! Maybe a bit more expensive but last longer and serve the purpose well .
We closed auto manufacturing plants in this country but we still should be able to deliver good windsurfing boxes.
