... This leaves me wondering - where to get a polyethylene strip??
Are Lego bricks really an option?
Totally confused and hoping for a miracle!
First things first. Dogoak got it right when he said

The repair will depend on the composition of the boat.
You haven't told us what the material of the boat is yet. If it's plywood for example, things might be different from if it's made of glass fibre reinforced polyester resin.
So to begin with you need to know what the boat is made of. As I said in my first post, it looks like these boats are made in more than one material but I don't know much about them.
Find out what material your boat is made of.
Polythene is very easy to mould and to repair. It's also very easy to find, for example polythene bags are (unsurprisingly) made of polythene. The trouble is they might have unwanted additives in them such as fillers for colour or even things to make the polythene break down in sunlight so you might need to be careful how you source the material(s) you use for the repair. Oh - Dyneema is polythene.
But don't get hung up on the details of the repair before you know what it is that you're repairing. As I said, polythene isn't the easiest thing in the world to get things to stick to but it's easily weldable with the right tools and techniques.
If you're completely, er, out of your depth you might just have to pay someone to do it. Can we take it that it's not covered on your house insurance or something like that?
