I am currently at Manoel Island Yacht Yard. They haul out
multihulls via a mobile crane, you can stay on board and do the work yourself. I am happy with the services provided, many chandleries are a walk away as are restaurants.
In Kalkara, you cannot stay on board or work on the boat yourself. And you are far away from chandleries or restaurants.
There are no other reliable haul-out facilities here in Malta
for your kind of cat.
