I have a 2018 Mirage 180 Oasis (tandem). I mistakenly ordered the incorrect Turbo fins ($137). So I sent them back and got the correct turbo fins that fit this mirage drive.
I am HUGELY disappointed with the fins. They are much smaller than the older version. They are only 2" longer than the original fins and cost more! ($160). At my calculation, that's $40 / inch. I'm also not impressed with the additional speed (or drag) it provides. I know I paid premium for a Hobie Oasis but I feel totally ripped off by the Turbo Fins.
Southwind was great in the return and buying the correct fins. Hobie totally let me down on this product.
