I used Chris on my Frers for the dodger and it was a very tough install and he did a grate job. However on the cruising boat I wanted a hard dodger and did the one Dave mentioned with Dan @ Canvas Creations. It's now over 8 years old and still going strong. Love the hard dodger and the flexibily we get with it including taking out all the glass but stilling having shade in the companionway down below
