Why would you want to cover up the anchor well?
The anchor well provides an ideal and secure place to stand when handling the head sail and spinnaker also the anchor, the well is self draining, and in spite of sitting in front of the fire in the winter time and dreaming of big waves crashing on deck and filling the well, this just does not happen in practice.
Where would you stow the lid while using the well any way?
Rob is right - it is one of the best features of the RL. It was always our kids favourite spot even though they had to hop inside the cabin when we wanted to tack.
However if yours is not a deluxe model which was factory finished, the bare fibreglass on the sides will look better if you give it a coat of white flowcoat.
Also I think the anchor should always be tied to the boat so that in the case of extreme winds, the anchor doesn't self-deploy. A hook to the shackle is all that's needed.
