In the Trintella 1 and 1a models, the weight of the mast is transferred via the steel mast base and the underlying mast support to the two bulkheads in front of and behind the toilet area. In (early versions of) the Trintella 1 and possibly the earliest versions of the 1a, there is a risk of the centre section of these bulkheads sagging under the weight and forces exerted by the mast. This bulletin outlines the problem and demonstrates the solution.
