Is it be possible to ship my old 50' Chris Craft over to Subic Bay ?

Hi everyone.. Im new to the site.. Anyway..

My question is.. I am looking into whether it will be possible to ship my old 50' Chris Craft over to Subic
Bay and have her launched there. I will be maintaining the USA registration / flag and will not be selling
Or registering the boat in the Philippines beyond just being a visiting yacht.

The idea is to do some wandering around e philippines for a year or so and heading to Malaysia, Indonesia and Thailand.

Does anyone have any idea what the Philippine Customs folks are going to try an charge me to do this ?

I know that if I just sailed into the islands from abroad the Philippine Govt. only requires minimal entrance and customs fees no matter how long you sail around the islands... So, if anyone has any helpful info or knows
I can contact to find out.. Please let me know..

Thanks in advance...
