Yamseng, you haven't really given us enough info.
What are you thinking of doing with it, ie, wave riding, free style tricks, or just blasting???
If you haven't been sailing that long, you probably don't want to go much under 75 liters, that should still just float you. If you're young, full of enthusiasm and learning quickly you could go for a sinker, if you want radical high wind wave riding.

Sorry, here's a little more myself:
1) I am only interested in blasting around on flat to choppy waters - no waves. I sail in the estuary in Australind.
2) skill level - I am comfortable with harness and footstraps. I can do tacks with 70% success and going into gybes with more agression but still to do one successfully. I still have not been able to do waterstarts. Best I have done so far is a half-way version in chest deep water. Finding it a physical and exhausting struggle to get sail and board in the right position. There is a suggestion that it would be easier on a short board.
3) Wind range - from say 20 to 30 knots. I doubt I will have the balls or skill to sail in any stronger winds. Went out in 25 -30 knots last Sunday on my long board and got hammered.
4) age - biological 53, mentally in denial. Motivation? Just one to go out there and have fun and mix it with the experts.

I'm with Bertie, wait until you can water start consistently before moving to a board that you can't uphaul on....unless you can sail at a spot where you'll always be in chest deep water.
If you've pulled off a water start in chest deep you're almost there, just need more practise. Rather than waiting until you're swimming to practise your water starts, you can practise them in shallow water simply by sitting down instead of doing a normal beach start.
On the other hand there are some pretty good free ride boards around these days in the 120liter category that would work well for you and given your weight you might be able to uphaul at a pinch.

I am in Bunbury too and have a board you can borrow for a week or two to see if a short board will make you water starts easier. It is a 1998 111L RRD Race board, which may still be a little big for the 25+ days, but, at 58kg will give you heaps of planing power in 15-20.

It is very light, 59cm wide, has nice vee for chop out the back and a 40cm Tuttle fin which may be no good for SW days in the shallows, but will rock on those channel runs on a southerly. If you have a 28-30cm tuttle she may be less harsh on your ankles.

The deck has had the odd bit of plastic surgery, so would not worry about hurting her, and sorry, she is not for sale.

Give me a call on 0418 940 088 if you want to have a look/go.

Gettin' gone!!! Seaton

Thank you all for your advice. I will persist with the water starts before looking at a short board and avoid anything on the high side of 20knots. Paddy, I do have a bouyancy jacket and will give it a try. I do re-call Reg at WSP giving same advice. Seaton, appreciate if you will introduce yourself. Just look out for that Chinese fella that has just got off his horse! Once again, many thanks all.
