I am the proud, but slightly frustrated owner of at least a dozen old windsurfing boards that are still in great condition, are still perfectly usable, but have been superseded by better designs (some a LOT better, some only slight better, but enough to make the difference that I never use them - except maybe once in a blue moon for nostalgic reasons). So these dozen + boards clog up my shed and take up space which I really don't like. That does not include the other 8 or so boards which have high historical or sentimental value - mostly old polyester speed boards which I call my 'Museum'.

or the old Race Roard, Formula, Go and a couple of tandems, between 35 and 10 years old, which DO get used a few times a year.
I think I have only one single board in there that is actually in bad enough state of disrepair that I could not use it, but it was such a favourite bump and jump (self built polyester) board that I harbour desires to rebuild/repair it some day.
I honestly can't remember EVER dumping a board in the Tip, but I have sold dozens in the early years when the designs were progressing very quickly. Hell, in the '80's I sold 40-50 new rotomoulded longboards in just few years in my small country town. I have not seen any of those boards for 30 years, so they are either all in Landfll now, or still hanging forlornly in garages all over town!
My point is, I have all these quite good, serviceable boards, which I will almost certainly never use again, that I can't really sell or even give away (I have tried with a few.

), and they are most likely destined to end up in the Tip anyhow, even if I could sell them for a song or give them away.
And I still have people around town bringing me serviceable old boards and asking me if I would like to have them, or know some kid they could give them to! Sorry - no.
