Corbie 5 Deck Experiments

I've been involved in doing some 3D modeling of another boat lately, and haven't been as attentive to the Corbie 5 IOM as I should be.

However, I've also been doing some thinking and some designing for the Corbie 5 deck. An idea was given to my by Ian Dundas of Scotland... he suggested that I 3D model a frame for the deck of the Corbie so that I could use it to plank the foredeck. It was a great idea and I did it. See previous post for 3D drawing.

It's an exact copy of what the planked hull curves and bulkheads will form, so a deck built on this frame will perfectly fit the actual hull.

Here's how the deck frame looks: (I just used a scrap piece of MDF, so please excuse the wonky cutting job!)

This picture is looking at the bow...

And this one from the back side of the main bulkhead...

However, right now, I'm considering not planking the deck and instead using some laminations of either 1/64" (.4mm) and/or 1/32" (.8mm) ply that has been cut out in an, let's say, artsy style.

Today I laser cut two different colors of cardstock to see how they would work and to check how well the deck form would work. Luckily I can say that they worked well!

Here's the two layers of cardstock being laminated:

And here is how the cardstock version looks!

No, it's not very "classic" but it's sorta fun. And since I'm not a huge fan of modern IOM boats anyway, I thought I'd give myself the liberty to mess around with ideas. It might be a bit too much for the rather staid wooden RC sailboat crowd, but for a modern IOM I'm fine with it.

For the final deck I will laminate two sheets of ply with the top sheet remaining wood colored and the second layer being painted... probably red. Right now I'm thinking that the top layer will be 1/32" (.8mm) and the bottom layer with the holes will be 1/64" (.4mm). The whole assembly would then get a layer of 6oz. (or two layers of lighter 1.4 oz. cloth) fiberglass cloth over it to cover the holes and to waterproof the deck.

Fingers crossed that it all works!

Aloha!

1934 America's Cup Rainbow J-Class RC Drawing

At some point I would very much like to model a vintage America's Cup yacht. The one I've been most interested in lately in the 1964 winner Constellation. But this past week I was sent a 1/16 scale drawing of the 1934 Rainbow. It's a beautiful drawing! Full sized so it's very large. I have been working on making it into a 3D model, but as is true with most hand-drawing lines, none of the lines from one view match up with the lines from the other views. For example, I spent a lot of time tracing the "sections" view so I could make stations. But when I tried to match them up with the plan/deck view or the waterplanes view, none of the lines met. Some came close, but all had to be adjusted. Then, once they are matched to the deck and keel lines, it's obvious that the hull is not fair. I honestly doubt that the hull would be fair if you simply used the station lines as originally drawn either. Back when they made these boats, they put it on the actual bu...

IOM Rig Box (IOM Sail Box) plans

So all the cool IOM kids seem to have nice wooden boxes to store their rigs in. This might be my next quick project then, so that I can pretend to be cool too. :-P The rig box images that I've seen online are mostly similar, and would work well, but David Jensen from Bellevue, WA, USA (The same guy who designed a fantastic IOM boat stand I posted about earlier) has a really nice design that he shared on RC Groups . Or if that link doesn't work, the go here and search for " IOM sail box " or " IOM rig box ". It holds three sets of rigs for the A, B, and C rigs. He also has a nifty way to attach his IOM boat stand, with a boat on it, to the rig box. His rig box has wheels attached, so once everything is loaded up he just wheels it to the launch spot. Very nice! There are other sources online. They show different variations of the same type of sail box. Here's a nice looking one . Here's a YouTube video of a really nice one . Wil...

IOM Sailboat Stand

I made an IOM boat stand! The plans are from David Jensen in Bellevue, WA, USA. I found the plans through someone else's blog here , and a model sailboat club from Australia here . It was pretty straightforward to build. My only contribution to the design is that I laser cut the cradle out of 1/8" Lite Ply. I made eight copies, and then epoxy laminated two sets of four each. Turned out really well. If you wish to laser cut your own set, here is my DWG file . You'll have to have your own laser cutter, or send the job to a laser cutting company like National Balsa . Here are the original plans , and here are the original plans for just the cradle . Thanks to David Jensen!! Note that in the picture below, my boat is not finished! Yikes. You can't see it in this image, but there's a small chuck of self-stick foam behind the bulb to protect the bulb. I'll eventually incorporate some Velcro or a strap of some sort to hold the bulb in place so...

A Wooden "Alternative" IOM RC Sailboat

Being forced to stay home due to the Coronavirus quarantine has had a positive impact on my boat building. I still haven't been able to sail my newly completed Vickers V8 IOM, yet have just planked and glassed a wooden Alternative IOM . It only took me eight days. It usually takes a couple weeks. I haven't been motivated to blog about it, but I started planking on 5 April and finished planking last night. Today I sanded and have fiberglassed the outside. The Alternative by Brad Gibson was a challenge to plank due to its up-swept bow and flared sheer near the bow. It turned out okay, but as any builder will tell you, there are goofs all over. One that I only discovered after sanding is a lighter colored plank on the starboard side. It really showed up after fiberglassing as the epoxy brought it out... GAAAAH! How did that get there? The other goofs I'll let you find, but that one is pretty obvious. Here's how it looks so far: Here you can see that mu...
