This isn't the first Invader thread here, which is lucky for me- I can learn from previous builders.

MassSailor's zombie thread, but what a good start: https://www.rcgroups.com/forums/show...ls-Invader-Kit

There'll be a fair amount of head scratching and a few more boxes of parts before I get started. First order of business- does anyone have better Invader plans? I saw a couple references to plans adequate to scratch build from, and these ain't them:

There are plenty of photos out in the interwebs... a whole bunch of hi-res images can be found if you're logged in at Shipspotting.com. I've grabbed over 100.

Great, an ocean going tug, my favorite ship model or otherwise.
Looking forward to the build Patmat.

Looking at the “ plans” it almost screams out a need for a lot of photographs.

I just went over Harbor Models specs on Invader and she will be a beast of a model once finished, I'm guessing final weight will be 60 plus pounds if not more, pretty impressive model and she will look great in the water, she is to scale water is not.

I rarely work from full size (model size) plans... and with a beast like this, the plans are really too much! So I folded them for occasional reference, and printed out photos on letter size sheets for frequent reference.

I can't imagine why someone would bother drawing up plans like this and not include at least a few useful dimensions. Like:

- The straight line of the bottom rises at 1.6į relative to the waterline (had to do some trig)
- The line up to the transom (stern counter) rises at 17į relative to the bottom.
- The deadrise angle near the rudders is about 14į (each side), but the bottom is built a bit convex. Still, useful to know when designing new rudder bases (the kit parts are all wrong).
- Prop shaft centerline is drawn parallel to the bottom (not a given!) and is 2-5/8" above the bottom.
- No indication is given for prop spacing. But 3 circles are drawn on the aft deck which look like rudder post access hatches, and these are spaced 3-5/32" to either side. These probably line up with the prop centers.

I have to agree, they are barely a general reference.

Pat, I have copies of the original drawings and photos of the boats from up here. There are different arrangements depending on whether you want to build the tropical, coastal, or Alaskan ( Valdez) versions.
