Boat building environment

Currently trying to prepare for electric 30ft catamaran project.

I didn't buy plans yet, but thinking on going with Jazz 30 by Woods Design Sailing Catamarans - Jazz 30 fishing, day charter or cruising http://www.sailingcatamarans.com/index.php/designs-2/6-powercats/438-jazz-30-fishing-power-catamaran

In the end decided to build boat for the most part myself and get help from professionals for more complicated stuff, like battery wiring, electronics, etc. But there is a problem, i'm not sure where i can build the boat. I have an option of using abandoned old building which has large enough space, but no windows or doors left, covered from rain and wind, but it can get rather humid during summer. To what extent i have to seal of the place or temporary shed will make more sense?

What kind of humidity levels might cause problems when working with plywood? Anything else to look out for?

If someone remembers useful web-pages or old conversations on this matter links would help out a lot.

 

How many boats have you previously built? A 30' cat is a huge undertaking and nearly an impossibility for a novice or first build. Building sites need more than you might realize, such as light, heat, the ability to close it up for painting, working with goo's or just general comfort levels on inclement weather days. This isn't to say you can't do it, but is to say you'd be a very rare exception.

 

I didn't build boats, but i can work with wood without "oh, this side turned out little bit short" Familiar with tools etc too. But i didn't touch epoxy in large amount and didn't work with fiberglass, from documentation and videos i saw about working with fiberglass and epoxy, doesn't look too complicated, time consuming, yes. I'm planning to spend about 4-5h per day and most likely will get extra hands here and there. Hope to finish within 1-1.5yr, about the time when i want to have my own boat. Most simple interior, return after day out, no living on board. Which also should cut down build time.

I think i can manage building hull, equipment installation most like will request a company or someone knowledgeable.
