Lot's of good creek boats out there. I prefer Pyranha, so that what I will suggest first. Burn, Shiva or Nano. Some other good options include the Jackson Hero and Villain, Dagger Mamba and Nomad and Liquid Logic Stomper.
Paddles. I prefer Werner, but Adventure Technology makes good products as well. I would suggest the Powerhouse.
Skirts. You want something with a rubber rand instead of a bungee. I had a Mountain Surf for years that I loved, but just upgraded to an Immersion Research Kling-On. Snapdragon makes good skirts too.
PFD's. There are lot's of choices in this department, and fit will be a big determining factor, but if your going to get into creeking you should probably get a safety vest. Astral's Green Jacket is becoming the standard, but there are many other choices out there.
Helmets. There are lots of helmet options as well, and that is another item that will need to be tried on. My helmet is WRSI (whitewater research safety institute), but know lot's of people who swear by Sweet.
Dry Gear. Best bet is a Kokatat Gmer drysuit, but that is expensive. You could also get a Rogue or one of their Tropos tops with dry pants, but the investment in a drysuit is worth it.
Also need to get a throw rope, river knife and emergency whistle. Never hurts to carry a couple locking beaners too.
