Starting now for 2018 Transpac is not as far in advance as you might think....especially if you have a job. I started about this time for 2016 with Ventus and was amazed at how much there was to do and how quickly time could slip by. It is comforting when you leave to have gone over every inch of the boat in detail....things will still surprise you...but the more you can take apart and put back together the better. The advice about spending lots of time sailing (given already) is excellent but at times hard to accomplish with boat prep. Enjoy the process it is part of the fun.
