Abstract: An anchor system with a bridle substrate and harness configured to attach to an anchor line. An outer bladder surrounds an inner bladder for coupling on top of the bridle substrate. Water enters the anchor system through a water inlet that feeds directly to the inner bladder and fills that first. Water then overflows from the inner bladder to the outer bladder to fill that second. The inner bladder provides stability and is positioned with a majority of its volume closer to an uphill end of the anchor bladder while the outer bladder is positioned with a majority of its volume closer to a downhill end of the anchor bladder. Reinforcement connectors for each bladder resist deformation of the bladders to resist movement of the anchor bladder while filling.

Other embodiment's of the system allow the implementation of a single-strut/wing combination and also a double-strut/wing combination among other variations. The design of the wing clamping apparatus allows the user to mechanically secure the wing and also configure the angle of attack of the hydrofoil wing. The modular design, configuration options, and high degree of interchangeability of the hydrofoil wing attachment system enables the user to experiment with multiple strut/wing configurations, wing/strut designs, and also the angle of attack.
