Too Late!
auto inflator device for the mast:
Try this
AntiCapsize Device And this for the instruction details:
Instructions Price listed on the website is $158 Eur including the VAT (16%)...so it's cheaper than the life jackets and the shape is better suited, volume is> higher. Mechanism is exactly the same (a salt pellet dissolves when submersed to release the trigger spring on the CO2 cylinder).
It would be easy to design a self-inflating mast float that's just a CO2 cartdridge and airbag that sit up top just for an emergency. (minimal windage and weight) It could be activated by a pressure switch that has a time delay, or by a tiny line that activates the mast top device.
Go for it!
