I have had a 170 almost since it was first introduced (3-4 years ? ago), and it has had its problems. My 170 is now out of the water for the winter so I have my year-end comments. This past spring (March 2001), the good folks at JYSailboats (the manufacturer) replaced my hull and also made and sold me a weighted centerboard. The prior hull had an unusal crack (not major) but also had 4 cup holders cut through the deck. During the few times I was able to sail the boat this summer (when it was actually windy and not 105 degrees), the boat was markedly more stable. I dock the boat during the summer and learned the reason for the increased stability when I hauled the boat out last weekend. When I removed the drain plug, NO water came out. Previous fall haulouts always resulted in a 10 minute drain of water -- probably about 20 gallons or more. It would appear that the water in the hull was the major cause of the instability. For the previous hull, the more I heeled, the more the water made the boat less able to right itself. Where did the water come from, you may ask? Thanks for asking. Those stupid cup holders, which leaked. (I understand that Hunter insisted that they be installed in an otherwise watertight hull design). A problem with the cup holders was that no adhesive could permanently glue the cupholders to the hull. The boat is still a bit tender, and I am very careful sailing it, but it is much better now. I also have installed a reffing point, at least ease my mind. So, if your 170 has those cup holders, I suggest making sure they do not leak.
