can't say we didn't warn you ... but don't worry, most of us learn the hard way too, even after being advised
[quote] I assume must place screwdriver or other object in each of 3 screw holes when screws removed, to hold inside plate in place; has anyone performed this task before? are inside the hull chainplates epoxied or fibreglassed to hull? all ideas and suggestions welcome.[/quote]
On my cat they are epoxied in but i don't know about darts.
You could always change out 2/3 screws at a time but if the nuts on the backingplate aren't welded in .... you may need to cut open a small access to hold them in place
when i broke a side stay chainplate (all internal) it was near impossible to unscrew the screws. we used some type of impact screwdriver my friend had that you hit (HARD) with a small sledge hammer and it breaks free a frozen bolt (not exactly what i wanted to do to my cat)
IF you need to cut open an access area i recommend you create a small opening just big enough for your hand (AND FOREARM)and cut it open like the top of a pumpkin (at angles) so it will sit in the spot without falling in (so you can re-attach it later.. less work in the end)
[quote]. If you use chain/rope, there is no give when a wave lifts the boat, the loads transfer directly from the end of the rode to all parts of the boat. [/quote]
I use 3.5' of chain and about 30' of 3-Strand Anchor Line. That stuff has a lot of stretch in it and is much better/softer on a boat than any type of low stretch line. ... but the more the wave and wind ... the more you need (as discussed in the other thread about mushroom anchor morning)<!-- editby --><em>Edited by MN3 on Aug 19, 2014 - 09:15 AM.</em><!-- end editby --> [/quote]
