Finishing Plug

[weldandglass]

I'm working on a 20'x 8' running plug. The plug surface still has a bit of "waviness" to it, particularly where the topsides meet the spray rails. It's not terrible, I've seen lots of tooling with minor waviness, but the perfectionist in me says "long board it again and flatten it a bit more". I know I'm reaching the point of diminishing returns, where the last 2% of imperfections takes 50% of the time you already put in. What say you collective boat design forum brain-trust? Call it good and pull a mold off this thing or break the long boards back out and go through another longboard-wet sand and polish cycle? See picture below.

I don't like the ripple in the cove. How are you sanding that? It is very hard by this pic to make a quality decision.

For the cove, I use pipe (as a sanding tool) of appropriate radius for my boat, not mould work. But it finished nice. The trick is blending the cove and the flat which should be relatively easy if the flat was done well first.

@ondarvr is really an expert here, see if he has a standard to go by

What color will the parts be?

You won't see it on a white part, but dark colors will highlight it.

What is the customer requirements? What will the ultimate moldings be used for? How important are aesthetics?

The product will carry your reputation, and you’d probably dislike being labeled “Wavy Gravy”!
Are we looking at a picture of an upside down hull?
Maybe you need a longer board?

Thanks everyone for your replies. Went back at it with the longboard today and I think it flattened nicely. We’ll see what it looks like when it’s polished up.

“Wavy gravy” made me laugh and yes, it’s a picture of an upside down hull.

ondarvr-the hulls will be a variety of colors so best to get it as close to perfect as possible.

Thank you again.
