I have used my AI dodger for quite a while. It works quite well to keep
spray off of your legs and really makes a difference keeping the wind chill
away from your lower body. It does increase the windage on the AI if you
are on a beam reach. But combined with AI tramps, it is not a bad setup.
I found that I had to add a small nylon 'flap' on the front of the dodger where it encircles the mast. If the AI buries its nose, a wave of water would pour under
the front of the dodger unto my legs. The added flap deflects most of the wave to the sides.
There seems to be two types of AI dodgers. One dodger has a front which completely surrounds the mast with a small flap-covered opening which allows you to insert the mast into the dodger. This dodger deflects waves better than the newer version. My dodger, which I believe is a newer version, has two front 'wings' which are fitted forward on each side of the mast, so that you don't have to remove the mast to fit the dodger. The problem with this design is that the gap in front of the mast acts like a scoop which directs water hitting the mast right into the cockpit. Which is why I attached a 'flap' using Velcro which fits in front of the mast helping to deflect water to the sides.
Good review Tidalwave. I have experienced the same issues but don't have your velcro flap mod. I might have to look into this further. Actually I have 2 mates who are making their own dodgers using mine as a template. Maybe they could incorporate your flap into the design - if it's not too late
Would a photo be a possibility
