Eric,
Last winter/spring I completed the job you are about to undertake - on a 1977 H16 boat and trailer. I too initially had concerns about manipulating/supporting the hulls in my garage. However, what I found is that the H16 hulls sit quite nicely upside down on saw-horses. I completed the hull bottoms first in this position. Later, I turned the hulls onto their sides (while still on the saw-horses) to do the tops. It worked out very well like this.
With the exception of the initial washing, scrubbing and contaminants removal from all the surfaces, I treated the hulls like two separate projects - hull bottoms first and hull tops second. Since I went with a two-tone colour scheme, this worked out particularily well...and necessary. But, I would do it exactly the same way again - even with a single colour scheme. It was convenient and it was seldom necessary to move the hulls as a result. Aside from the convenience, not having to move the hulls is important if you are using time-sensitive resins, and even more so if you decide to paint and desire a great finish coat.
If you are interested, I have included two links/posts I made on another web forum. The threads are long with lots of good info. There are many photos. There is also step by step information you may find of value.
Although I am new to the Hobie scene, I am not new to boat restorations and working with composites.
Hope it helps you out,
Dave
