My boat will be an L-size as I can't fit the S (or M) by a long shot :o
However, we do have a young lady in our team who would be dying to try your (or anyone else's) smaller sized boat as we have only big boys' boats (1,90 75+ kilo boys) at the club.
Most of us work during the week (shifts) so we do most of our group training during the weekend (strength training on our own/small groups during the week).
Anyway, I'll contact the polo committee and see if we can get a date. It would be fun. Just in case, would it be fun to have a friendly tournament with Rijnland as well?
