In looking at the Hull Number Index and Builder Chart, there are some big gaps, especially within the DS 1. According to the chart, O'Day did not manufacture a DS1 in 1973...yet I just bought a 1973 O'Day Daysailer1, sail number 6872.
I would like to take on the task of updating the chart with your help. Send me your hull number (if known), sail number and manufacturer. Over the winter, I will compile a list and update the chart.
Send mail to rnlivingston@verizon.net.
