Three months ago I acquired a miracle 20. And thus inherited the deferred maintenance of all the previous owners. The daggers have some light splitting (see image) and the rudders have splitting on both leading and trailing edges. They hum violently when sailing even in a small breeze.
Are they likely to take on water that i need to drain? one dagger weighs 10lbs and the other weighs 13. I'm looking for any advice on how to repair them all. Are they foam core? or fiberglass?
Newbie is thankful for all advice.
