The Lazer was made from crosslink poly. Linear poly can be patched,
unless something changed crosslink can't. They are different plastics.
Most companies use linear or some version thereof now, in part because
it is cheaper, in part because it can be fixed.

I'd be curious to know if technology found a way to do it.

If not, I have a friend who may have a Lazer hull still in the wrapper
(he trashed his, ordered a replacement hull when it was possible to do
so, and then switched to a more modern kayak and never did anything
with the hull). If the boat can't be fixed, I can ask him if he still
has it, and what the price would be. It is in Colorado.
