Yannis.... very interesting
1. I see the vehicular ramp is functional......
2. I also see from the first posting image the fulcrum lifting point is strangely low @ approx. 1/2 of the total ramp length
3. We also see safety chains fitted
...are the chains to support the ramp's water tightness @ sea?...as the chains appear to be non tensioned ...or slack in this image
4. Is the construction of your ramp sufficiently lead weighted to allow it fall under it's own weight when lowered via the wire cables?
5. Will you use some form of gasket between the inner ramp edges & the hull to maintain water tightness?
