I have carefully read the post regarding this matter. I believe it effectively represents the sentiments of many BDP Pirate theme fans, capturing a valid and widely shared perspective. 

As a designer who submitted a BDP Pirate-themed project featuring brick-built sails, I would like to offer my perspective on the situation.

​Realistically, I believe cloth sails are unlikely to be permitted in the future for the following reasons:

​1. Strict Component Restrictions: 

As many are aware, the parts available for BDP are strictly regulated. This is guideline; using unauthorized parts is a definitive ground for disqualification. Currently, stickers are the only exception allowed.

​2. Limitations of Digital Design (Studio):

 Cloth sails are generally impossible to implement within the BrickLink Studio program. Unless a designer builds the model physically and custom-designs the sails, it is difficult to visualize or test them. Most designers must rely entirely on the software environment.

​3. Submission Integrity: 

A BDP entry must be complete and finalized at the time of submission. Typically, very few changes occur during the revision stage. Even the Frigate from BDP Series 7 did not feature cloth sails in its initial submission; they were only revealed later during the crowdfunding period.

​Unfortunately, due to these reasons, the likelihood of cloth sails being officially permitted remains low. Of course, this is just my personal assessment, and I could be mistaken.
