I don't know anything about the Prindle but the angle of the existing bow tang should give you an idea of how it will be mounted. If its flat verticle it may be as simple as bolted to a bulkhead and that would be a relatively easy fix once in the hull. When cutting into the hull make sure you don't make a cut on top of a bulkhead as you wont be able to get your arm in the hole
