Alternative IOM Interior Bits

For whatever reasons, I've been too unmotivated to do much blogging about this Alternative IOM RC sailboat build. But I'm making progress regardless. It started off quickly after planking it in only eight days. But now I've slowed down.

I've installed the interior bits now. The true IOM jockeys that are shooting for top in the world will never want this boat because a woody is too heavy for them. They'd look at my inside bits and say that it all weighs too much. For them, that's true. But for most people this boat will work well.

It's too early to gauge the weight, but I'm hoping for as close to 100 grams of corrector weights as I can get. It's a heavier boat than the V8 though, for sure.

All that said, this will be a strong boat.

Here's how it looks so far...

This is how it looks as of today after I installed the scoop deck.

But if you go back a week or so, I've done this... Made my own fin box.

And I installed the mast well and side frames to support the fin box. You can also see where the future rudder servo will be installed and the winch servo plate will go, but neither are in the picture.

Here's after the scoop deck aft wall was installed. You can also see the shroud anchors. They're just laminated pieces of cedar bonded to the sides. After the deck is installed I'll just drill through and bolt the eyebolts through.

I need to re-cut the aft deck. The original one I drew is off by a couple millimeters and it's worth it to cut a new one.

Slowly making progress on planking the foredeck too, but it's my first attempt at planking an IOM foredeck so no laughing when it's done!

IOM Alignment and Measuring Jig (UPDATED)

I need to start to consider how I'll mount the fin and bulb, and get it all straight, so I made a 3D modeled alignment jig:

Ian Dundas in Scottland sent me pictures of his setup. I just bought a laser level too! He does amazing work and has been a great help in this project so far.

There is also another jig featured on page 14 of the winter 2008 Canadian Radio Yacht Association (CRYA) newsletter that features one. It's by Lawire Neish. Read it here.

I took both those designs and made my own version that features sliding cradles for the hull, a fixed waterline sight, proper depth to cradles for the bulb, etc... Most of the parts can be laser cut, and the two end pieces and the base can easily be cut on a tablesaw.

It has fixed waterline sights that are 420mm above the top edges of the bulb sliders in the base. The fore and aft cradles can be slid up and down to adjust the waterline of the hull. You'll see that the overall interior length is 1003mm to accommodate the aft…

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.

Will post more if I actually end…

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 that I can use the carry-han…

Rip Tide RC Sailboat

Well I just hit the R/C Sailboat jackpot! Rod Carr, of Carr Sails in Redmond, WA, and the second ever member of the AMYA, just gifted me a Marblehead "Rip Tide" hull and many of the parts and templates to finish it! Thank you Rod!

I'm not sure when I'll be able to work on this, but hopefully it will turn into a fantastic vintage Marblehead. The gentleman who started it did a fantastic job. He was a true artist and I will do my best to get as close as I can to his workmanship but it will be a challenge.

Here are some pictures...

He even cast his own bulb and the mold came with the hull! I could probably start making my own fleet of Rip Tides as he also gave me many of the templates and such. I will only need to pin and epoxy the bulb to the fin and fair it smooth. It will be easy to do.

The frames look and feel like he hand cut them on a scroll saw, but they are very close to perfect. He used thicker plywood than I may have but they are very sturdy. The bow is very s…
