Vintage Marblehead Rip Tide electronic files

UPDATE: As of 12/8/2017, I was sent a much better TIFF file of the original plans by Ted Houk. See my updated post

When Rod Carr gifted to me an unfinished wooden Rip Tide hull, it came with a CD of files from the gentleman (a man named Roger, I believe) who made it. I finally got a chance to look at the files and what a great discovery!

Roger created not only several very helpful PDF files, but .dxf files too. With some work I could make files for laser cut frames, fin and rudder!

NOTE: I am not the creator of these files and cannot vouch for the accuracy of them. The creator of the electronic files is unknown but the original plans for the Rip Tide go back to 1949 and are most likely in the public domain. One version of the Rip Tide lines is being freely distributed. These files are the only ones I've seen other than the original 1949 hand-drawn lines. I put them here under an assumed Creative Commons license for NON-commercial work. You are free to make your own Rip Tide but only for personal use. IF the creator of these files can ever be found then they might give full permission, or may otherwise restrict the use of these files.

These files are VERY cleaned up from the original 1949 lines. If you are talented at making CAD files then you will easily be able to make a file for laser cut frames. If you do make a laser cut frames file PLEASE let me know and send a copy. I can post a link here too.

IF you do make a file for laser cut frames, please be sure to check the Vintage Marblehead rules to ensure accuracy. I CANNOT GUARANTEE THE ACCURACY OF THESE FILES AND CANNOT SAY IF A BOAT MADE FROM THEM WILL COMPLY WITH THE RULES. Use them at your own risk.


You can see all the PDF files here. The .dxf files are available here. NOTE: As of now (April, 2016) there is not a file currently ready to cut laser cut frames. Someone would need to explore these dxf files and create a specific file for the frames. Please let me know if you do this. Good luck!



  1. Hi i have several VM’s and wonder if it would b possible to get full size template drawings for riptide i think i would like to build her.

  2. I was wondering if it would be possible to get a full size drawing of the station templates for riptide i would like to build her.


    1. Hi, I have taken these files and had them printed at a local printer here in Victoria. They are full sized working drawings. I did not have to do any resizing on any of thise pdf files to match scale, it was all there.
      Thank you very much for posting these. I am building two hulls simultaneously off your these files you so graciously provided here.

  3. Hi Cyril,

    Unfortunately there really aren't any "full size plans" that I have. I've only 3D modeled the Rip Tide from the lines that I have. With the software that I use, there really isn't a magic button that converts the 3D model into plans... it's not how 3D software works (at the software that I can afford!)

    If you're really serious about building one, please email me and we can chat about how you can buy the laser cut frames from National Balsa. They are charging about $225 including shipping. That's as close as I can get to getting you accurately sized frames.

    Otherwise, take the lines plans that are posted on my blog somewhere and have a local copy place run a full sized copy that you can use to make one. Make sure that the LOA of the prints are 50".

    Good luck!

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

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

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

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 t
