Conversion of Sea Queen hull to Navy Launch
I have both a Sea Queen and a Picket boat, the working version of an Admirals Barge. A fellow club member has an Admirals barge and I attach photos of all.
As you will see the Sea Queen is a totally different shape to the barge and will not be an easy conversion.
If you can build from a plan there are plans for Picket Boats (Admirals Barges) and it would probably be easier to source the correct plan rather than to try and convert a different hull.
Good luck with your model
