I found, when I was building my boat, that you can easily get run down - basically you can work all day, all evening 7 days a week and that's not a sustainable thing to do. With the cure cycles of resin there is always the temptation to do the last few jobs in an evening and get it glued/glassed or whatever so you don't loose 24 hours on a particular job. This job will take you quite some time so pacing yourself is important or it will all turn ugly.
That being said - if you're racing with Ken against me then I think the best thing would be to put in a full days work on the boat followed
