Was the possiblity of Madeleine being taken away by boat ever investigated by the Pj ? I've personally haven't found any witness statements from the people whose boat the children were taken to in a dingy by the nannies.
IIRC The man seen by the Smith was heading towards the beach.
from where he was seen by the Smiths he could have been heading
South towards the rocky tiny beach and any number of places,
East towards the Church, Sergio Malinkas and the main little town of Praia de Luz ... any number of places
But not west (have proved that in another thread)
OR, could have been meeting up with the getaway car that seemingly had scarpered previously.
With the tidal conditions, the rocky foreshore and the roughening sea, it seems unlikey to me that he would have gone down to that little beach. but it is not impossible. Desperate people do desperate things
ETA: Since this was written, I have given this more thought.
Instead of a tiny boat being on that beach, which is only rocks at high tide (no sand), it is possible that a larger boat at sea sent a small boat in to pick bundleman and madeleine up. Bundleman could have then waded out up to his thighs maybe and clambered on board this little boat to be whizzed away to safety.
I still think that the original plan was for the getaway car to pick him up on Jane Tanner corner and whizz them away to a boat somewhere. As that failed, cos of Jane Tanner witnessing it all, he took refuge at his accomplises flat in OC Staff Quarters. There he phoned for instructions and was told to either go to a house/flat elsewhere, to a certain place where car would drive in and pick him up ... or to walk down to the beachy/rocky little cove ready to be picked by boat there.
It is a tricky way down, but someone who regularly did it and with a torch shining from his his head might do it. It is also possible that there is a smugglers tunnel to that cove. Then it would be easy.
But Heri thinks differently and I acknowledge that he might be right.
it is more likely that, with the pick up failed, a boat came in and picked him up. before being taken out to sea and the rendevous with a larger boat. One was moored under 4 miles away at Lagos harbour, just outside the gates to the harbour. Moved out there just before the gates were closed for the night. In other words ready to go. May not have been that one, but it might have been. That boat had connections with a name in the case. Cant remember which for absolute certain, but have it recorded somewhere.
I have ideas where that boat went to, but they are only ideas. However the ideas fully fit around other sightings and the timings are perfect, whilst the drop off point at around dawn (semi darkness) is quite isolated with excellent adjacent vehicle access. Only ideas tho; like my * sadies theory *. Like that everything is plausible.
