I wish things were different, but significant sponsorship from any entity in marine industry for offshore racing is unlikely. When your choices are employing people or providing race support, you go with your employees.
But there are smart people involved in OSS and I'm sure they've thought outside the marine industry and are looking to lure non-endemic (i.e. nothing to do with marine) sponsorship dollars.
The most obvious problem is the economy. But even in a great economy, offshore racing (not matter how much we love it) is a very tough sell.
