One very important thing you should keep in mind: the way we build our models with straight planks over the full length of the hull was in fact not how it was done in real life.
When a tree was sawn to planks the building master choose the planks which where most in line with the hull of the ship. And these were not straight over the full length. Very often the part of the plank which should come at the bow already had a bend downwards, and was further shaped into the correct curve.
Then it was formed as shown in the post here above, with moist an an open fire. In this way you had a plank which fitted the hull quite easy.
The Batavia was built by Willem Vos and his crew in the period of 1985 - 1995, and in 2015 he wrote a book on how to built an East Indiaman. This book is as far as I know only in Dutch - and you have to be very well into shipbuilding in the 17th and 18th century to fully understand what he means. But I have taken one photo out of this book where you can see the form of the timber and the planks cut out of it (#6 in this photo).

Then back to our model building. The usual kit comes with straight planks and we have to struggle to bend them in two directions, over the wrong side and often twisted as well.... This is not the easiest thing to do - especially not when it is a Dutch ship with a blunt bow and flat bottom. Many of you follow Heinrich and his ship of Willem Barentsz. The hull of this ship is a bit challenging, but in the end also very satisfactory when done.
The new model we (= Kolderstok) are constructing - a Dutch Fluit - has pre-formed and pre-cut hull planks, and even with these it still is not an easy ship to build.
