Are there any drawbacks with the vertical split building system?
Probably the biggest problem is the traditional mind set that resists change, a common problem in sailing and boatbuilding. However, remember that the traditional building method of the upside down hull, then turning it over and fitting the deck was developed to suit materials of earlier times. Modern materials are not subject to the same limitations, and one therefore has to look at how these can be best used. A possible disadvantage for some may be the need for joins in the main cross bulkheads, but these take very little extra time compared to cutting out and setting up form frames for another complete hull. The smaller bulkhead sections are also much easier to make and handle, requiring only an 8 x 11 (2.4 x 3.3m) flat area to assemble or vacuum bag versus an 11 x 24 (3.3 x 7.3m) area with a full width bulkhead. Another possible disadvantage may be painting, whereupon with the traditional method the upside down hulls can be painted from gunwale to gunwale prior to turning over. How
