hi grahowler,
all of the boards mentioned are not the best to learn on.
tyronsea is total crap (poor universal joint design). styrotech is to easily damaged and hifly lacks stability (hull shape). avoid all old school gear completely. except maybe a windsurfer one design. one designs are superb and very cheap. try and avoid a one design with an old sail and boom, that is no good. you need a more contemporary sail and boom. one designs with really old triangle sails are no good. the newer one design sails are a lot better and easier to manage.
for modern gear something like a second hand wide board is more suitable. when i say wide i mean 85cm and up, but avoid race gear as it is made from carbon and easily damaged. starboard "go" etc are great, but a little expensive.
look for a wave sail to start with, they are more forgiving and durable. probably a 6-6.5m would be a great size and maybe a 5m sail as a second sail.
a fibreglass mast is better than a carbon mast for learners and a clamp on boom is a must. don't buy a boom that needs to be tied onto the mast with rope.
you should definately get lessons. maybe you won't like the sport.....? if you are nervous about buying from the newspapers then the 2 places that i think will give you the best advice on gear aren't in brisbane. you should talk to either
Peter at caloundra wind and surf.
Deiter at sunshine coast sailboards.
both those guys have been around for a very very long time and stock some really great secondhand gear. they also tend to have more learner type gear around as well.
don't buy any gear that says slalom, wave, race etc.
most sailing around brissy is done on flat water and some of it is not very safe for a beginner. board crazy does it's lessons at manly and that is a good spot. the swimming pool area at wynnum is good in a NE or SE. Thompsons esplanade, victoria point in a SE is good spot at high tide, the northern side of Wello in a northerly is good but muddy. i think the 2 best spots are either gold coast broadwater at southport, south of the swimming pools in front of the big carpark area. or the passage at caloundra.
a good video to get is Windsurfing made easy with Tom Luedecke. you can find it at most libraries. cleveland definately has a copy.
the things to remember are these.
golden rules
1. always learn to turn around first...... this is a must.
2. only sail in onshore conditions when learning.
3. line up something on the shore to see if you are drifting.
other than that. it is an absolute blast. best sport ever...
