Hello jgb1787, I used to work for a company in Melbourne called RMK Marine. I built a design called the Oceanic 373. The difference is in finished mouldings and how much you are willing to work.
The Spirited Kit is Canoe moulds and top decks round. The rest of the design is made from CNC Panels which you have to Fill Fair and Sand. Hey I am not saying its a hard boat to make, but its all in the finishing.
Personally If I had the time I would go and sail one first. Contact the designer and ask for a sail.
You will have to be extremely realistic about a 12 month timeline. Personally I think it will take double that. I would employ a couple of boat builders to Sand Fair and spray your boat for you it will save you a lot of headaches.
This is the Kit we used to make... Still available I think... Have to shoot of an email to RMK - Richard ... rmkmarine.com.au
