Oh should have said... If you were to go with a launch trolley kit rather than a home design - then in the future (next year

) you could then decide to buy the other half of the combi...
If you really are after just a launcher and have some metal work skills you might want to drop me an email - I have a T shaped one that is about 2 years old. But I think I said above I had the T made longer to fit on my old road trailer and it bowes under the weight of the boat.
If you could shorten that you could be on a winner.
It came flat packed. Think it cost about £20 shipping - but not sure about to NI. If you want pics etc just email. Otherwise I'm keeping it just for the wheels as spares!
