This morning, we started with a discussion of our feelings of drawing a plan in AutoCAD. The small boat was designed for beginner boatbuilders, so as the plan itself.We got six sheets of plans. And guess what, everyone seems confused, because we can not decode the plan.As we were asked to draw the plan in AutoCAD, we found it is so difficult to duplicate it because we can not find enough measurements!
This proved a fact: for a boatbuilder, knowing how to use AutoCAD is far from enough. AutoCAD is powerful and useful tool, but you need to combine boatbuilding knowledge with your AutoCAD skill in order to get expected outcome (we have done several drawings in AutoCAD: tool box, oilstone box, stem section, deck camber, scupper hole...I think everyone in the team now knows how to use AutoCAD and has got basic drawing skills). That is why programmes such as AutoCAD are only computer-AIDED design programme.Luckily, the course of boatbuilding is the exact process for our learning of boatbuilding knowledge. Chris showed us this morning the relationship between the faying surface and the PT (Plank Thickness).Actually, this is one of those difficulties we had in yesterday drawing. The length of the faying surface is PTx4.This is one of those important rules for boatbuilders.
How is it?
An excellent blog here Wei.
With your reflection first, then the sketch I'm sure that you will remember the faying surface rule for a chine. Remember that this is a broad rule and may change, but it is a good starting point.
The small boat is called a "Firebug".
If you could keep doing blogs like this then that would be a good thing.
Cheers
