Just for information:
I found replacement bow tangs which are at least 2x thicker ! I'll replace both items just as precaution. grin
Fellow H16 spi users at our club and also nearby club take same action - also on Wave with spi!
[will upload pictures later]

And now for something completely different:
Although saling with spi some years now I have just recently been told my spi doesn't open up aft as it should. confused
Did some test by moving the block to aft. About mid tramp gave amazing improvement: better control, speed and able to sail higher !! :DCan start using spi sooner now.
So still learning but occaisionally you need some help. blush
By the way: seems newer original Hobie spi is cut more flat so does not need moving of the blocks to aft ??


Happy sailing from The Netherlands!
