She's looking great. Can't wait until you get to the planking so that I can get an idea of the difficulties, if any.

Big Boats Rule!

Mike, what are you thinking of for the top hatch? I could see a solid block of balsa with a magnet to hold it down. Plank the top same as the deck. It would be nearly invisible. Of course, you could also make it look like a hatch or something. There is always functional storage lockers on boats.

Thanks Babble, I'm getting ready to start the planking shortly and will post pics of the progress. It will be a bit of a challenge since you are required to tapper some if not most of the planks at both ends of the boat. I usually get started by measuring the hull bottom and sides at it's widest point and then determine how many planks it will take to cover it. Then I do the same at the bow and stern so this will give me some idea of how many planks to tapper. One good thing is, this is a double planked hull, so the first (balsa) layer can be applied any which way the main goal is to get it covered. The second layer (mahogany) is the show finish, so care must be taken here to get as close and as neat a fit as possible. The least amount of filler or putty that is used here is better because once finished the filler tends to stick out like a sore thumb.

Hi Dave, I'm with you on the invisible hatch, I quite often use magnets versus latches, for ease of use. But, I'm thinking of making a former to match the shape and contour of the opening and then use some two thin layers of plywood sandwiched together with epoxy. I have used this method in the past and you could just about stand on it without it losing it's shape. But I'm far off from that yet and still thinking about. I still haven't found that negative action yet for this modification, but I'm sure it will show up sooner than later.

I have started the planking with the first layer of planking which is the balsa strips. I did what I usually do to most kits is to beef up the framing, which are 1/8" plywood. I used some scrap wood strips to beef up the edges of the frames to about 1/4" thickness, which will help the planking lay better and easier with more surface to secure it to while the glue dries.

I have the first layer of hull planking about finished with a few odds and ends to clean up. Dumas gives you a template to use to form the bow and stern area with a hard wood or hard balsa, once you attach the wood, you then have to shape it to form the nose and rear of the boat to match the contour of the hull.

I have the drive train all ready for installation when I get ready to put it in.

I finally broke down and ordered a glue accelerator when I ordered more Starbond super glue and after my first few uses with it, all I can say is, where has this stuff been all my life. All I could think of was what could have been 50 ship and boat models not to mention airplanes ago. One thing I know for certain, I will never build another model without having the accelerator on hand.

This boat was my first build and came out pretty dam awesome (for a first build) except that I didn’t have access to the rudder and the rudder linkage came undone AFTER finish. So can’t run it unless I cut it open. This was a learning point for me in always making sure I have adequate access to rudder linkage even if I have to modify to get there!

Thanks PD, that is exactly the reason why I decided early on that the conventional way which is access through the top versus Dumas ted way which is through the bottom was the best way to go. Even using a rubber membrane in my opinion, could be a problematic issue from the get go.
