Moe If I recall correctly the teak on your 49 is only on the cockpit sole, not the entire deck. I'd definately stay away from anything like Cetol or Varnish as they're both slippery when wet. Some folks have recommended teak oil. Another option is a water based product called Teak Guard. Easy to apply, looks good, won't stain gel coat, not slippery and lasts all season up here in the Mid Atlantic region. Just google it and you should find a couple of sources for it.
