I have a 1999 Chris Craft 200 and I bought my swim platform from
www.swimplatformsuperstore.com
On their website they state that they don't currently offer international shipping but that it will "change in the future". They also state that they will work with your shipper, so maybe you can arrange international shipping on your own if you choose to go with them. The platform comes in a crate which should be able to go just about anywhere.
Now, I did have a few problems with the company but in the end it was mostly resolved. First, they shipped me the wrong platform after I waited 11 weeks. This was in 2016, not Covid related. The company and I agreed that the platform could be modified to fit the contour of my boat in an effort to avoid shipping the platform back and waiting another 11 weeks for a replacement, so I hauled my boat to a fiberglass repair shop for them to do the modification. Initially, the swim platform company coordinated everything and offered to pay for both the labor and the installation. Once I arrived at the fiberglass shop, they gave me a different story, stating that the swim platform company told them that I was on the hook for the installation fee. The swim platform company wasn't fast to respond via email or phone calls, but all in all, it worked out. My family and I have really enjoyed the platform and it looks great and considering how small the previous swim platform on the boat was, I don't regret the addition at all. I don't know that I would buy from the same company again though.
Good luck!
