When I acquired "Papillon" several years ago it had no stern ladder. Dale Tanski noted in his reconstruction section, still available, that he had a new ladder done by Tops-N-Quality. I contacted them last fall about a ladder and they sent me drawings that Dale has supplied and asked a few questions. I ordered a ladder several weeks ago and when it arrived I was very impressed with the quality. I will put on my transom after the snow melts and know it will be a welcome addition.
You can contact the supplier at http://www.topsinquality.com and reference the Pearson 365.
It is nice to find good suppliers that provide quality product.
