I’ve started working on frame D’ (also referred to as D1 in the CNC kit), one of the most important frames in the entire boat. This frame will carry the compression loads from the mast above, and it does so through a compression gate — essentially a strong beam supported by vertical posts and a solid wooden block at the bottom. This post covers the work done so far in preparing and assembling the components of that gate. Compression gate When I first studied the plans, along with photos and blog posts from other builders, I noticed some discrepancies, as different builds seemed to use slightly different configurations. I asked in the builders’ Facebook group and got mixed responses, with someone pointing out that the original plans themselves show two different versions: a generic compression gate on page 2 (bottom right), and a specific version integrated into frame D’ on page 4. Frame D' - 60cm between the posts Compression gate (page 2) - 72cm To get a definitive answer, I went ...
