+# AdmiralDao Staked Sail
+
+This strategy returns the voting power of an address that has staked sail in the vesail staking contract [VeSail](https://etherscan.io/token/0x26fe2f89a1fef1bc90b8a89d8ad18a1891166ff5). 
+The voting power is calculated as:
+- The amount of vesail held in their address. 
+- The result is then used to interract with the tosail method in the contract to get the sail equivalent.
+- Lastly it will take the equivalent sail amount and apply a square root operation.
