so managed to get a bit more done
shaped the hull and filled in tiny gaps and general making the shape a bit more rounded and smooth
also added the comin ? not sure if correct word 4 strips of wood around opening in hull.
this is when I found out about section I should have cut, for the cabin you have to cut corners of the middle frame of cabin for it to slide over hull.
primed just the cabin for now ......... starting to think about electrics next

filled in round top of boat

some pics of my trials
superglued then filled round edges

used this filler from wilkos only 2 pound per tube for wood and easily sandable

roughly filled when set round the edge

cabin now primed
lightly at first

two more coats
