The latest proposals have been dreamt up by a firm of local architects, probably off their own back, without anyone commissioning them. Can't see it would have taken very long to draw those proposals up.
To my knowledge (and from their website) they are a well established local firm, with no experience what-so-ever in berth/port design.
It's their own admission that the primary goal/driver of this design was to provide more parking space! (and whether that is necessary is debatable)
I am quite surprised (as probably were the DoI) at these proposals, as there appears to have been no consideration or consultation with anyone having a marine background as they would have immediately pointed out that berths are supposed to provide shelter/calmer waters - this completely exposed berth doesn't in any way and as drawn is totally unviable.
All the proposal is doing is creating more noise about cruise when an expanded port including a deep water berth should be the focus, to ensure the Island has resilience for its lifeline services, and provide opportunities to explore multiple different revenue streams.
