Hello to Will R.
I read that you experienced "wheelie Inter 20" surging at 27 kt...and that you were diving through "walls of water"...
Could you tell us if you were pulled off by a spi with a very positive bow-up trim angle or if you manage to put yourselves back as far as possible...because calculations show that an INTER 20 hull need at least 5 to 7° of incidence to be able to plane at such high speeds...
Thank you,
Frenchie
