Whoooah there little dogie...
Let's see, expected budget divided to two does NOT equal 50% of original budget x 5!
Not in the view of my 'bank manager's' eyes anyway.
We'll see...
One option I've 'sorta' already kicked about is, reproducing all 5 at ~ the same scale and then creating an open ocean diorama(?) as a comparative display.
So, while the project has increased in size, each vessel might need to reduce in size to accommodate room and budget.
At the moment I need some dimensions and a ton of graph paper, and maybe some of those off-grid hydro 'vegies' of your's.
Cheers.
