Hi Roger,

Just finished framing up the hull and am ready to put the first planks on. Even with all the pictures, I still find putting on the first plank confusing. It appears that this plank should start out in the bow at the level of the shear, work its way back following the break of the knuckle and ultimately getting to the aft end of the hull. What made the lay of this plank very clear is that when you removed the hull from the workboard some planks still had to be added to bring the planks up to the shear or deck level. This then makes it abundantly clear how this plank should run because after it passes the knuckle area it just takes a natural run aft. Otherwise this plank needs to take some twists that would put stress on the hull.

I hope that you get back to the build steps soon because I will soon catch up.

Regards,

Iran

I just received my plans from Floating Drydock and made a few observations about the position of the prop shafts. It seemed to me that boats/ships with two props never placed the props on the centerline of the rudders. With an offset, more rudder authority can be achieved using the prop wash. Unless my measurements are off, the prop shafts should be approx 1 3/8 inches from the centerline. Also, the scale size of the rudders appear to be less than 2". Another point is that the tip of the prop hub seems to point to the bottom of the rudder. Since I have not put in the prop shafts yet, this seems like the thing to do. Also, I am going with the 1.7" Prop Shop props. This is slightly under scale, the scale size if the prop is approx 1.85". The 1.7"props have a 3/16" shaft and I will be able to use the Dumas stuff. The Dumas stuff was a sizeable investment and I hate to set it aside. I will definitely make new struts per Rogers extras section.

Any comments??

After visiting Rogers website many time in the past, I acquired the Dumas Crockett. I would like to share some of my observations. In my particular kit the wood quality was quite poor. The plywood was separating in the sheets that had the hull formers. It was very nice of Dumas to replace the several of the die cut plywood sheets although the new sheets were not too much better than the originals. The instructions are very scant. I am not sure of the date of my kit. It is very possible that this kit is an early one and perhaps Dumas improved the quality somewhat. It's nice that Roger was able to sift through them and come up with an improved building plan.

I built up the hull and found it very difficult to follow the instructions that Dumas provided. I put planks 1, 2, 3, and 4 on in the opposite order. As it turned out, it made planking much easier for me. However, the planks meeting at an imaginary line past the keel was very deceptive. I decided to add a piece of balse along the stem of the keel and shape the balse into a crude shape of the cutwater of the bow. This gave me a visual reference as to how to run the planks at the bow. The sheer knuclke came out quite nice and I think it will look good once painted. The hull has been glassed and yes it took a bit of elbow grease to smooth things out. I also used two coats of resin.

The deck turned out to be a little larger than the outside dimensions of the completed hull. A little trimming was necessary to get the deck to conform to the shape of the hull. Perhaps due to the two sheers not spaced properly when attached to the frames.

Happily, I am past what I hope is the difficult part and am looking forward to the rest of the build.

My first question for Roger and the group. When assembling the rear hatch where the Bofors mounts, is the frame section under the hatch discarded or is it used to maintain a camber in the hatch itself.

Looking forward to some discussions on this build,

Thanks
