for a beginner, 1st time going into the water to try out, will
prob keeping trying n falling for 10mins, then tired liaoz n will
want to rest
2nd time go into water if can stand up, confirm cannot last more
than 1 or 2 minsm. max abt 3 mins then will tired n fall...
maybe can go 2 or 3 rounds..then will get back up to boat n rest
again
last round to go down, maybe can go another 3 rounds of 3 mins or
so again
n though total only abt 30mins, tats all a beginner can take for a
day, trust me...after tat they wun be able to wakeboard liaoz
n next 2 days, whole body will ache like crazy, as if just ran a
marathaon :p
so 5 ppl in a boat for 3 hrs, timing is just abt right.
