Either check out surf sails australia, they stock lots of parts or get in touch with Stone surf, he might be able to sell you one.
We've never been able to buy them, so that is a welcome addition to the stock, thanks Mark at Surf Sail ![]()
The weight looks good too, most of the placcy ones were too heavy and 75g isn't too bad
Only thing is that flange is 3mm thick. Thus when routed you will have no hi density foam left at the perimeter, you will be setting the entire box into styro. Will need a divinycell block large enough to ensure the flange sits on top of hi density foam to prevent it rolling.
Still $20 vs $80 and not too heavy I reckon its a winner
I have never seen that Chinook box , it's of the material that US box, and others are made from, its not a carbon / cell/ G10 set up like others have. I have gotten Cobra ones from USA Tabou, Simmer from Hawaii-through Black Project Fins, the best IMO are Flikka, that use G10 as reinforcement , and supply with internal hex screws.
it will be heavier tan carbon ,
i have been tempted to make my own, but still have a supply.
