I would not have called a 10 metre boat a "small yacht", but that's just me.
1. If the boat is in Johor Baru, Malaysia
, I guess you have the choice of shipping
from the Port of Tanjung Pelapas, in Malaysia
, or moving the boat to Singapore
. Shipping schedules will tell you which route
(PTP - Fremantle or Sin - Freemantle) is best.
2a. Before that you might need to consider whether break bulk carriers are common on either route.
2b. The alternative is probably to top load on a 40' flat rack. A 40' flat rack is 12 m long, about 2.4 m wide, and about 2.6 m high. Of course if it is top loaded, the height is not a limitation. Your hull
width of 3.3 m is a limitation, but it depends where that broadest beam is - and if you are top loading, you can make sure that the flat rack is on a side edge of the stack.
3. Flat racks usually need to be ordered in advance. Not every port has a few 40' flat racks sitting around waiting for a load.
4. If you go the flat rack route, once you have a flat rack you will of course have to bring the flat rack to your boat yard to load and pack. And before that you need to check the road from your boat yard (bridge heights, width limits) to the port.
So in order, you probably need to look at:
1 (Sin or PTP) at the same time as 2 (2a break bulk carrier or 2b flat rack)
If you choose 2b, then you need to think about 3.
And before you commit to either Sin or PTP, you have to have 4. a viable road route to the port.
A good freight agent will sort out most of those questions.
What's stopping you sailing to Darwin and then coasting to Fremantle?
