The oars look ok ,with regards to row locks i thought the zodiac ones were crap the avon ones seem much better ,but you could for emergency use just make a loop with some rope and thread it through a lifeline eye or even wrap a lifeline/grab around and use that ,
the rnli use a webbing strap as rowlocks on there inshore lifeboats .
if you do use the ones to glue on make sure that they are in the right position ,not a bad idea to slip the oars on the new rowlocks and see what the rowing position feels like ,not end of the world and depending on the size of the boat but its sometimes better that the locks are fitted a bit further to the bow than aft of the half way length of the boat as the boat will row in a straight line better .
some glue on ones can be a real pain in the arse when the oar is forever jumping out so you really need to get ones that will fit your size oar shaft .
Hi, i'm in the same situation.
I've got a 3.8m bombard with no rowlocks/oars, but been told its relatively easy job.
All you just have to do is make sure when you order the kit that you ask/tell the supplier what your boats made of (hypalon or pvc) because there are different glues for different materials.
Try IBS Boats International Ltd, they seem to have a very extensive spares catalogue and i found them to be very helpful.
Think this is the sort of thing you may need.
Good luck and do let us know how you go on
My 14' Achilles had the pin and ball type locks as in Uny's lower photo. They actually worked pretty well the couple of times I used them (usually when maneuvering around areas where divers were down.) They do require oars with holes to reveive the pin, however.
If I only had to go a short ways, it was usually easier to use the oars as paddles, and canoe your way over to where you needed to be.
Either way, paddling a SIB is not the most efficient endeavor in the world...
