How secure is shopping in the Online Shop? Is my data protected?
The NSA, with the biggest cybersecurity budget in the world, has been hacked recently, as you might know from the press. So nobody can 100% ensure anything on cybersecurity.
That said, we are very privacy and security-conscious and have done and deployed many advanced technologies to keep your information protected (sorry for the techy terms ...):
- Our platform updates are automatically managed by Shopify, the global leader in e-commerce. Access the latest Shopify Compliance reports.
- Our system is protected at the DNS level by CloudFlare, the leading DNS and Internet Security provider, from DDoS attacks, man-in-the-middle and many other attacks. See detailed info here.
- Complementary security and privacy measures are in place directly by us.

Also, our support team receives one and the provisioning workflow is initiated.
A controller will be internally assigned to your specific order, in charge of personally assuring the picking, shipping, and dozens of details required to ensure the best experience for you.
Once the shipment process begins, you will start receiving notifications both by email and SMS on your mobile phone constantly updating about shipment status, which will be specially relevant in cross-border shipments, for yachts in transit, and to avoid many different issues than can occur during domestic and international shipments. Our delivery guarantee without issues exceeds 99,5%, greatly increasing the sector average, due to continuous supervision of the shipping agents and constant updates provided to our customers, ensuring both parties are acknowledged about each shipping process step.
