the puzzle piece joints, pre-drilled holes, minimal clamping on coaming (not bent around deck panels), coaming spacer is a 1/2 piece of ply, hull develops around bulkheads, trueing is easier than CLC hull shape, recessed coaming is more ergonomic and doesn't require extra bracing like on AT. If price is an issue then you probably already have a little extra this or that and could get the partial plywood kit for $375 and glass/poxy from RAKA.
