The General Cost Chain for importing is structured as follow not only for boats but more or less any item imported :
1) Price of item
2) FOB ( Free On Board ) charges (Departure Port) - all the costs of getting the item into or onto its shipment vessel -postage box/containers/bulk carrier.
a)Transport
b)Storage cost
c)Clearing
d)Terminal handling
e)Any Specialized logistical costs.
3)SeaFreight - a 40ft container to the USA costs +- $6100 incl BAF (price of oil)so assuming the same costs from USA to SA
4)Fob costs (Arrival Port)
5) Import Tax - 7% + 14% VAT on Commercial invoice.
* a $10 000 boat can very easily cost $20 000 considering the cost chain, import costs seem less relevant to more expensive boats as relatively to cheaper boats.
