Btw Capn. I tried as best I could to make them even with the deck but that is another story. Nothing aligns as it should and dropping the deck is not on my radar. But... it was a good point to know and I tried to get as close as I could while maintaining some of the Tiger alignments
Probably the route to take would be to carve off (or fill) moulded detail on the hull, where it is errant, and drill pilot holes through from the inide.
Doing one side at a time would allow being able to "match" the fore-aft of the other side's mouldings. Also, to give a height of opening reference.
At least to need.
Given the sheer on the decks, scuppers and freeing ports are only really needed at the "quarters" and not the extreme ends.
There will be some "ports" used for mooring lines, but, that's a judgement call, too.
Nostly those will be handy for spotting whatever "bumpers" the ship has out. In the earliest days of such trawlers, those would be tires. In later years, they would be the round floats common to fishing craft.
These are blow-mouded PVC about 50-60com in diameter
Either in a teardrop, or sphere-and-disk shaped.
The nets will have "through-ine" floats:
Also PVC, typically blow-moulded. Diameters from 15 to 60 cm, lengths from 20 to 60 cm.
In previous eras, net floats might be cork, or cork and kapok, evensome hollow glass, back in the day.
Much of that can be answered with a trip to the bead section of one's nearby craft store. (And some of those might be usable straight from the package, too)
Viz:
(holes are a bit overscale, but the colors are not far off.) Also:
At the scale, 1.4mm = 1cm, so a person coul be forgiven for using 1mm = 1cm for sizing.
If a person were at, say, JoAnne for beads, if might be worth a troll over to fabrics to see if they have green tulle:
As it's going to be a dead ringer for modern trawl netting.
Modern nets are in blue, red, and ocher/tan.
The nice peope at JoAnne are generally happy to sell a person a foot off the roll rather than an entire bolt (10 meters of tulle would be a lot of nets . . .)
