Re. Punctured floats. I had that happen a few times when using my inexpensive single-skin float that I used for a decade (I have several floats), usually away from home. I found the 3 following fixed it ok and quickly for me:
Superglue, clear sellotape type tape and self-adhesive bicycle puncture patches - "buyer beware, your mileage may vary".
No punctures in my little-used solid float, of course. Nor any punctures in my more recently used plank-style "double skin" float (skin + bladder) that I can recall. But I usually carry superglue and/or self-adhesive bicycle tube patches in my spares bag, in the car, so punctures are inconvenient but not such a big deal for me now.
Sorry to hear about your covid Bobby
. I just had yet another booster against it last week. Sigh.
BTW I use Rob Allen "Thai green curry"/"olive green" polyester thin rope float line. I use several different lengths, works well. Orange version probably safer for you. I've not seen this rope in shops but I did find something similar in a car--boot sale - apparently used in garden! Also found some NOS English washing lines which are similar (but thinner and lighter green, but available in other colours too -red might be good??) and cheap.
