Bow launch wheel?

[Nstr]

I have a Hydroforce (formerly Tobin) 3.3m SIB, I'm moving to the south coast and looks like there are some nice properties within walking distance of the beach. Unfortunately my car isn't compatible with a towbar. I've seen launching dollies for hand launching but they seem to go under the whole SIB. I've rigged up a pretty effective golf trolley setup which hooks onto the D ring on the bow, but wondering if anyone has found a good solution for hand launching in such a way as to not have to leave anything on the beach - something collapsible or foldable, or that stows up, that can attach/detatch from the bow once it's in the water? "Bow launching wheels", if you will? I've seen a couple of things online but they don't look particularly stowable - better suited for keeping them ashore.
