Beautiful photos, @tobetada :-) Yes, the boat shape is very interesting in Celtic, Nordic and other cultures: it can be seen also as a vesica piscis (the sacred geometry often used in churches, and older ritual and cultural ways, which represents the cross-over point between two realities - like, where one circle and another overlap: the point of meeting, of shared reality or of the 'sweet spot') - which can relate also to the sacred feminine and the yoni - the yoni is often symbolised in ancient art as a vesica piscis: the yoni, the birth canal and the cervix are all intimately literal and metaphorical representations of moving from one world into the other - from the inner to the outer, from the world of water to the 'dry land'. The older cultures were much more in equilibrium with the deep and sacred feminine, whereas the modern cultures have very much oppressed, occulted and diminished the feminine. There are epic movements in the study of the sacred feminine unfolding right now, and in our collective womb conscious; this is revealing far more about, e.g. historical artifacts which previously have been interpreted very dryly and 'intellectually'.
