Size of Vee Shape of dock for a 230 and 200

[boatbuddy]

We are rebuilding our docks and I was wondering if anyone had suggestion for dimensions for the Vee shape portion of the dock for a 230 and 200

Currently our boathouse has rectangular slips and boats are being stored during this work

I want to add a vee shape to the front of the slips to provide better access around the boats

Any suggestions based on experience

Thanks
