O’Day Daysailer Oneida Lake
Hello. I have just become the proud but anxious owner of a disheveled O’Day Daysailer II, and the questions are piling up already! Firstly, there is about a four foot length where the deck and the hull are no longer attached. I can prise them apart quite easily. Naturally I would like to reattach them - any advice, in particular what sealant/epoxy/glue/brand of duct tape? Thanks in advance.
