I'm currently working on a dragon boat directory website named Dragon Boat Helper under the domain dragonboat.help. The website has many objectives (but I'll keep this post short), and one of them is to provide a list of available/useful resources (Dragon Boat Resources & Guides) to the dragon boat community that paddlers can reference on their athlete journey.
I've only added a handful of https://dragonboat.help/resources/websites that I have come across in the past, but I figured that there's more out there on the interwebs that people here have come across. If there is a resource that you would like me to add, please let me know on here and why.
