I owned a Patrik 140 litre hollow board. Used it with a Hyperglide 8m and 50 Z fin.
I would plane before the majority of foilers though they would keep going in the lulls better.
Did i enjoy using it?
No farking way.
Nigh on impossible to turn and harsh when the wind picked up in the chop.
Sold it and yet to regret it.
Bigger and heavier components with a larger sail also.
6.3 is as big as I'm going to go these days.
Yes it limits my planing threshold to about 13 knots compared to only 10 knots with the big gear but it's way more fun when on the plane.
In any case at 58 i need my rest days bad as in real farking bad.
Yesterday on the water at around 3-30pm and when i checked the time in my car after getting my wetsuit off it was 7.01pm.
Half an hour of rest talking to slowboat about CT

and the rest sailing in 20 to 30 knots on the river.
Today my body is well farked but i did enjoy / love the 3 hours.
