I delivered a catamaran
to palma,that was then transported to Singapore by sevenstars,i then flew out to deliver the boat to pattaya in Thailand
seven stars were great and we used the agents they nominated that handle all the customs
formalities for their shipping in those ports
,agents charged 600euro in palma,and 600US$ in s'pore,which included a local skipper
for loading and unloading.
seven stars will weld temporary supports under the vessel for transport,so no cradle needs to be supplied.
in Singapore is quite strict,and you will need to have a bill of lading from your European agent,a current registration
certificate for the boat,and current insurance
with a wreck removal
clause for Singapore and details of their Singapore agent,plus email
copies of the crew passports to the agent for your access permit
to the port if you are going to be there for unloading.
