The mooring cleats are an appealing choice (strong, already there) and my only reservation is that they are occupied doing there primary job most of the time, so fitting jackstays becomes an extra task to be done once under way. The other alternative seems to be to drill some holes in the toe-rail and attach with shackles there. While at it, I would probably add a couple of extra holes to improve water drainage from the sidedecks. The snag would be that the inner surface of the holes would be unprotected against corrosion. Would that be a problem? Is there any easy way of providing corrosion pretection?
