I know that i need a bigger board but would this be sufficient?
What beaches are suitable for windsurfing around Perth (im from Hamilton Hill) and is the best time to go out when the wind is 20knots and over?
If you learn on a 102 you'll be a superstar before you know it. Go and get a bigger board, at least 140-180. You'll learn so much quicker and you increase your enjoyment ten fold. In 12 months you'll be blasting on a 102, but take the time to learn everything about this great sport and try and make it as easy as possible. Unitill you first plane your not really hooked.
A 5m sail is good to learn with, light and easy to handle...but you'll soon be looking for something bigger, Something about 6.2-6.7 seems perfect for WA IN about 15-20 knots...The 5m will be for the 25-30 knot days.
To start with try days when it's 10-15 just to get the basics down, on a 102 you might need a bit more wind as it would only just be floating. once you've got a good feel for it try 15-20, work your way up and get use to it.
With the 102 you'll spend so much time just trying to keep your balance it'll just make everything else seem that much harder to learn, try and borrow or hire a beginers board for a while, you'll only need it for a season and then you'll be on something much smaller. If your not short on coin buy a beginers board and the sell it after you're done, they are pretty easy to sell and have good resale value if their only a season old.
Can't help with the beaches...I'm only visiting but WA is the best place you could pick to take up this sport.
Have fun.
