I have a excel 435 and a honwave T38.
From experience I can tell you that a winch is a game changer, I can now launch the excel from most beaches even on its road trailer.
I only really take the honwave when there is not a 90% garrantee I will get out, if for example the weather is patchy
We have upgraded this year to a petrol winch to make it even easier.
With a sub 100kg setup you may find the balance of a launch trolley/trailer will help with one person recovery. Getting the boat in balance makes a big difference.
Another option would be to keep With your current setup and move to a dual launch and recovery, take boat down first then engine on a trolley.
