I didn’t know either, i kinda discovered it by accident. It’s good stuff.
I normally just cut the hose at the barb then cut (and pry) what’s left off the barb. For the really tough wire-reinforced hose an oscillating multitool with a bimetal blade works well for this and is easy to control. If I need to lubricate the barb for installation I typically use dishwashing soap. Might have been an old motorcycle trick for hand grips, can’t quite remember. Used to use hairspray For that as well. I’ve used heat to soften that hard corrugated sanitation hose for installation. (Boiling water or a heat gun) I don’t use that hose any more though, the rubber Italian stuff is so much better, and is therefore cheaper in the long run. Hope that helps.

Hi Dave- Thanks for you message and I like your suggestion. I did not know there was a more flexible version of non-collapsing hose. I thought about using reinforced PVC and did not realize it might kink so you saved me from that mistake. Have you tried to get the softball hose off and on a barb yet? If it is easier to remove, that would solve my problem. Have you considered using grease to help? Dave

Anywhere there’s vaccuum (I.e. cooling intake) for sure you’d want a non-collapsing hose. (Negative pressure more an issue than positive pressure)
I had a fibre reinfoced clear pvc reinf sink drain hose kink at a bend point and replaced it with MPI series 110 hose, which was much easier to work with than the stiff Lloyd’s approved stuff I had used elsewhere. I’ll use it to replace the clear stuff on other through-hulls in future.

David,
There is an ABYC standard: Hoses that connect to underwater fittings should be manufactured to SAE J20R3 as a minimum and marked as such on the outer surface.
They are reinforced (and yes, stiff). You could use wire reinforced clear hose. Less stiff than the black or sanitation hose.
Joel I am wondering if there is a reason why one would need to (or want to) use a thick, stiff hose for a sink drain connected to a seacock. It makes bends difficult/impossible and makes it difficult to remove the hose from the barb. It seems like overkill in a situation where there is little to no pressure on the hose. Something like Tygon/PVC tubing would seem adequate and much easier to work with. I would think the same would be true for the raw water cooling hoses. Am I missing something? Dave
