That's interesting ,would have expected more Bang for your buck,I think basic hull is right.(not going to plug mine or anyone else's work) like a lot of mdf kits they just don't hit the mark for me ,mdf is great for industrial and hard edge engineered items .organic shapes and I do class 'sail 'as an organic,and organic shapes,is where the modelling verses production time/costs verses volume of parts ,becomes an issue,and mdf stumbles.and the reverse is also true for resin models.
These chaps would have better success with a puffer/fishing boat,Tramp Steamer,and River boat.If there using the method you've mentioned the hard edged shapes of these are idea and there's a huge gap in the market just waiting to be exploited ,for any kind of late 19th early 20th century vessel.
Then I'd be singing there praises (also my commission rate would drop like mad
)
In fact it would take very little to convert either model into a fishing / coastal cargo boat a simple cab/ wheel house would be an easy addition as would a funnel,straight into the interwar ,pulp,VBCW ,markets.
it's not that I don't see a use for them it's just not the one marketed,
