1. A trim tab comprising: a first end comprising a first member; anda second end positioned rearward of the first end, wherein the second end attaches to a marine vessel via an attachment device, and wherein the first end adjusts pitch, roll or yaw motion of the marine vessel,wherein the first member has a first surface,the first surface is forward facing,the first member is pivoted about a portion of the attachment device and extends below a second surface of the marine vessel while in a deployed state,the first surface of the first member is convex-shaped, such that the first surface curves outward in a direction away from the attachment device, andthe first surface of the first member deflects oncoming water when the first member is extended below the second surface of the marine vessel. 2. The trim tab of claim 1, wherein the first member is convex-shaped and curves outward in a direction away from the attachment device. 3. The trim tab of claim 1, wherein: the first member is a plate and includes a third end and a fourth end; andthe first surface extends from the third end to the fourth end. 4. The trim tab of claim 1, wherein the first surface of the first member curves outward in a direction towards the oncoming water. 5. The trim tab of claim 1, further comprising a second member that extends from the first member to the attachment device and attaches the first member to the attachment device. 6. The trim tab of claim 5, wherein the second member is wedge-shaped and comprises: a third end connected to the first member; anda fourth end connected to the attachment device,wherein a width of the second member decreases from the third end to the fourth end. 7. The trim tab of claim 5, further comprising a third member extends from the first member to the attachment device. 8. The trim tab of claim 7, wherein: the first surface of the first member provides a forward face of the trim tab;the second member and the third member are sides of the trim tab; andthe second member and the third member restrict an amount of the oncoming water from flowing around and behind the first member. 9. The trim tab of claim 1, wherein: the trim tab is wedge-shaped; andthe first end is wider than the second end. 10. The trim tab of claim 1, wherein: while in a retracted state, the first member does not extend below the second surface of the marine vessel; andwhile in a deployed state, (i) a first portion of the first member extends downwardly below the second surface of the marine vessel to deflect oncoming water, and (ii) a second portion of the first member does not extend below the second surface of the marine vessel. 11. The trim tab of claim 3, wherein the first surface extends outward away from the attachment device and upward from the fourth end to the third end. 12. The trim tab of claim 3, wherein the first member is in an upright position during transitioning of the trim tab between a fully deployed state and a fully retracted state, such that, while the first member is in the upright position, the third end is above the fourth end. 13. The trim tab of claim 1, wherein the first member comprises a third end and a fourth end, wherein the first member: is positioned such that the third end is higher than the fourth end;has a fully retracted state and a fully extended state; andwhile in the fully extended state, is in a position relative to the second surface of the marine vessel to prevent an amount of oncoming water from flowing over a highest point of the first member. 14. A system comprising: the trim tab of claim 1; anda computer that controls a position of the trim tab. 15. The system of claim 14, wherein the attachment device comprises at least one of a hinge, a shaft and an actuator. 16. The system of claim 14, further comprising: the attachment device that attaches to the marine vessel rearward of the first member;a sensor that generates a signal indicating a position of the trim tab; andan actuator connected to the trim tab, wherein the actuator adjusts a position of the trim tab,wherein the computer signals the actuator to adjust a position of the trim tab based on the signal generated by the sensor. 17. A trim tab comprising: a first end comprising a member, wherein the member adjusts pitch, roll, or yaw motion of a marine vessel; anda second end that attaches to the marine vessel via an attachment device,wherein the first end rotates about a portion of the attachment device,the member having a first surface,the first surface is forward facing,the member extends below a second surface of the marine vessel when transitioning from a fully retracted state to a fully extended state,while in the fully retracted state, a bottom surface of the member is above or in alignment with the second surface of the marine vessel, andwhile in the fully extended state, the member extends partially below the second surface of the marine vessel,at least a portion of the member is not below the second surface of the marine vessel, andthe member extends at least from a first point, adjacent the second surface of the marine vessel, to a second point below and rearward of the first point. 18. The trim tab of claim 17, wherein: the second end is positioned rearward of the first end;the first surface of the member is convex-shaped, such that the first surface curves outward in a direction of oncoming water, anddeflects the oncoming water when the member is extended below the second surface of the marine vessel; andthe member is connected to the attachment device such that the member is moved downward and rearward when being transitioned from the fully retracted state to the fully extended state. 19. A system comprising: the trim tab of claim 17;the attachment device that attaches to the marine vessel rearward of the member; anda computer that controls a position of the trim tab. 20. A system comprising: an attachment device that attaches to a marine vessel; anda first trim tab connected to and positioned at least partially forward of the attachment device, wherein the first trim tab rotates at least partially about a portion of the attachment device between a fully retracted state and a fully deployed state to adjust pitch, roll, or yaw motion of the marine vessel,the first trim tab has a first end and a second end,the first end is positioned forward of the second end,the first end comprises a first portion and a second portion, wherein the second portion extends forward of the first portion and away from the second end, andwhile in the fully deployed state, the first end extends at least from a first point, adjacent a bottom surface of the marine vessel, to a second point below the bottom surface of the marine vessel. 21. The system of claim 20, wherein: the first trim tab includes a wedge-shaped body including a first plate at the first end,a second plate extending from the first plate to the second end, anda third plate extending from the first plate to the second end;the first end is wider than the second end; andthe second end is connected to the attachment device. 22. The system of claim 20, wherein: the first trim tab is attached to the attachment device at the second end via a second member; andthe first end is convex-shaped and curved to extend away from the second end. 23. The system of claim 20, wherein: while in the fully retracted state, a bottom surface of the first end is above or in alignment with the bottom surface of the marine vessel; andwhile in the fully deployed state, the first end extends partially below the bottom surface of the marine vessel,at least a portion of the first end is not below the bottom surface of the marine vessel,the first end extends from the first point to the second point, andthe second point of the first end is below and rearward of the first point. 24. The system of claim 20, further comprising: an actuator connected the trim tab and adjusts a position of the first trim tab; anda computer connected to the actuator and controls the actuator to adjust the position of the first trim tab. 25. The system of claim 24, further comprising a second trim tab, wherein the controller controls a position of the second trim tab independent of the position of the first trim tab.
