Need help hitec sea nymph

[Vintagerider]

Hi all new here I have picked up an old sea nymph and would like to make it operational again but it has no rudder was wondering if anyone had some pictures or diagrams of what it looks like I can fabricate one via 3D print but have no idea what it looks like.
thanks in advance
