Good wind in winter at St Kilda - at last

Session 91, Saturday 26 June 2010
Kite: Switchblade 14m
Location: St Kilda
Wind: 15 to 22 knots SW to W
Duration: 2+ hours
Weather: Cool but some sunshine

I had coffee with Brendan, an old friend, at the St Kilda cafe overlooking the beach.  He has a boat moored in the marina which he slept on the previous night.  There was little wind while we sat and chatted, but it picked up when Brendan left at about 10:00am.  I rigged up and got going on my directional board.

There has been very little good wind during winter of late so I have been hanging out for a good session.  I have booked to go to Bali in August on a Ben Wilson Wave Camp so I am also keen to get some more experience on my directional S-Quad board.

Some wind at last!

The wind was around 15 knots initially, and the half dozen kiters out were scratching around for wind close to shore.  A westerly at St Kilda is onshore so it can get a bit crowded at times near the shore.

I was able to get going upwind better and stay out from the fray a bit.  I haven't tried gibe turns on the board yet so at the end of each run I stop, grab the rear, spin it around, reset my feet then get going.

The air temperature was around 13C and the water quite cold, but my nice new 4/3 steamer wetsuit, booties and neoprene gloves kept my quite warm as I dropped in the water for these turns.  In the shallow water I walked out past the shorebreak before restarting.

To get going I grab the rear footstrap and poke my foot in it with the kite gently pulling to the right. I then bring my front (right) foot to the front foostrap and poke the toes in it too, with a wiggle to get them in.  Some power in the kite then whoosh - up and going.

It was great to be out again after a longish break.  After about an hour the wind picked up to around 20 knots so I was able to go upwind and get some good speed up.  I tacked as far as I could along the beach getting up as far as Middle Park, then returning to the Marina breakwall.

The limiting factor turned out to be the muscles in my forearms - they were aching from the exertion.  I hooked my palms over the bar to rest them and also had short breaks while turning.  I came in around 1pm, trying a few carved turns and riding toeside down, which was not too successful with the seat harness.  So I did some slalom turns onto toe side without actually executing a full turn and landed my kite.  Tired but very satisfied.

Note the wind chart does not show all the day's wind due to an apparent problem with the Fawkner Beacon data feed.


Driving along beach road a rain squall came through so I think I left the water at the right time.

I dropped in at SHQ to buy a replacement line knife as I had lost the one tucked in my harness pocket.

I am also sussing out what to take to Bali and how to carry it.  I may take my directional board in its own bag with bubble wrap around it inside the bag.  It is a bit too long for my main gear bag.

The advice was to:

  • Kite in surf without a safety leash and let go of the kite (pop the IDS) if you crash so that waves don't rip the kite apart.  This only works on non-crowded beaches though, and where there is no rocks on the shore.  Then paddle the board in without the kite.
  • Use a 10' board leash to keep in contact with the board, but use on that will break if very heavily loaded for safety

A new waterproof camera - Pentax Optio W90

I used my Pentax Optio W80 camera underwater while snorkelling at the Low Isles on my recent trip to Port Douglas.

To my horror, it started to malfunction in the water, well above its 5m depth rating!  Sea water got into it.  I returned to shore as soon as I realised but the damage was done.  When saltwater gets inside a digital camera it is basically dead.

I researched options for a replacement and chose the W80s successor - a Pentax Optio W90.  It is rated to 6 meters and a waterproof case will be available rated to 40 meters.  I have read a couple of user reports that this camera has leaked while snorkelling too, so caution is in order using it underwater.

Used in a kitecam rig, the camera does not tend to get very wet.  It might get splashed if you crash your kite, but it doesn't really get immersed.

I read the manual carefully.  Pentax recommends "replacing the packing" regularly.  I contacted the local Pentax service agent and they recommend getting the camera pressure tested annually - if they find any leak they replace the packing (waterproof seal on housing flap).

Now I just need some wind to test it out.
