See the link below for some flush deck fittings that worked very nicely on my Pygmy Arcic Tern (I couldn't bear the thought of putting those cheesy plastic do-dads on my nice wood boat.) They will accept 2 bungees running through them.

I installed them on the deck before mating the deck to the hull. This allowed me to glass right over them, then cut out the opeinings with an X-acto knife after the epoxy had cured for a day. This will help prevent the dowel from pulling out if it happens to get an excessive load.
