Photo via Leo Foltz from an old Common Sense News. Masts folded in tabernacle. Age creeps up on us all. This AS29 is out of Virtual Sailor . The AS29 design was very carefully thought out, with everything based on use scenarios.
Builders alter the carefully thought out design at their peril.
Even so, most of the AS29s in existence have at least minor changes to the design. Luna is a distinct design, based on the AS29 hull but heavily modified for the builder's own desires. The Foltz's boat is also modified. It's been through several design cycles, currently being built as a junk-rigged yawl. Both of these boats are best regarded as derivations from the AS29, not as AS29 variants.
