I have just spent the last hour...(with interruptions) responding and then
lost post when sending...I must be short...if needed send me pm and I will respond or call you...
sorry for confusion...
yes suggesting installing toe rail or tee that can tie in area that is missing flange only...
maybe a metal shop can fabricate a tee that you can use to mount the vinyl rub rail as
well as screw/bolt deck to hull.
do not remove remaining good flange, that is holding the deck to hull and keeping
boat rigid.
by corner piece I mean piece of
wood (2x2 or2x3) that can be installed in interior corner where deck meets hull (using
epoxy or adhesive with screws or bolts. this will provide for
lost support caused by missing flange...this may make for better looking exterior but you will have to still seal outside joint from elements.
the vinyl rub rail was most likely originally attached to the flange with adhesive to keep a
water tight seal...you will want to attach any loose sections with adhesive again.
How long is area with missing flange?
What make is boat? there may be a active users group...which may have passed this way before?
Is missing flange area near hi stress area such as chainplates?...I see its near your
jib track... keep stress away from missing flange area until repaired.
Best I can come up with short of a total joint job.
The joint and adhesive between the deck and hull is 45 years old...you may be able to gently tighten tighten screws on the balance of flange or leave well enough alone!
Hope this helps and does not add confusion. Good luck.. Hugo
