Hey Wouts, I disagree with most of the board advice given here.
Indo is crowded, the Mentawaiis especially, unless you go total off season and feral it out in the rainy season (take plenty of fansidar if you’re hardcore enough for that mission).
Your going to be shoulder to shoulder with guys who’ve logged thousands of hours at hollow, shallow reefbreaks.
If you’ve never surfed these kinds of waves before there is a learning curve and your gunna be on the wrong side of it.
Take a good paddler that you feel comfortable on.
6’7" would be a good one board quiver.
As far as fitness goes, it definitely won’t hurt but there’s no substitute for time in the barrel.
Ask anyone who’s been to G-land recently who stands out and they’ll say Scardy and Dibbles (guides at Joyos camp).
Their training regime consists of smoking gudam gurangs like a chimney and drinking their own weight in bintangs every night.
Dibbles is probably carrying an extra 30 pounds around the mid-riff yet he sits deepest, takes off latest and gets the kind of shacks that’ll have you shaking your head in disbelief.
He laid it out for me in simple terms : ya gotta sit deep, take off late and be able to ride the barrel.
Also noticed that Murray Bourton (super experienced shaper) made the recent observation that most guys in the Ments were riding under-volumed equipment and struggling to catch waves.
Don’t fall for the Kelly syndrome mate.
No offence to you, but if you’ve grown up in the Netherlands you’ve never even seen what a long period southern ocean groundswell looks like when it hits a 3 foot deep reef, let alone surfed one.
It ain’t fukn tiddlywinks and guys get seriously hurt, mostly from my observations, from having the wrong equipment for their experience level and fucking up on the drop or getting caught in the wrong spot.
The other thing I would recommend slightly off tangent is hanging on one spot and getting it wired. You’ll quickly find that the guys who get the best waves have a particular reef wired and no where to sit and which waves to catch.
Put the time in and you’ll be one of those guys.
Early season is less crowded than late season now.
I’d recommend April.
good luck. Steve
