Back at it with a new boat! And... it's an IOM... Gasp!

Hi! I'm back for another boat build! This time it's an IOM.

Yes, I know that it's not a Vintage Marblehead. Or vintage anything... it's a design from 2004. But this boat really looks cool and I want one.

The boat is the Laerke IOM designed by Søren Andresen from Denmark. Hopefully he'll contact me and give me some pointers.

And before all you hardcore IOM sailors start to tell me that the Laerke is an outdated design from way back in 2004... I know, but I will maintain that it's probably still very fast! I don't care if it's the fastest or not... I just like the design. Please remember that my entire interest in this hobby is in nice looking boats that A.) look like proper boats, and B.) can be made in wood by reasonably talented home builders.

The Laerke looks great and modern IOM's don't even look like boats. Besides, to be competitive in IOM's you have to spend a fortune to keep up with everyone else. I have no interest in buying my way to sailing victories... I just want a beautiful wooden RC sailboat. If a boat has to be made of plastic or grp, and has to cost thousands just to get to the start line with everyone, and then hundreds more each year just to keep up with the Jones's, then I have no interest. The guy with the most money always wins, but I'll have fun at the back of the pack with my pretty wood boat.

IOM sailing is too competitive and too expensive for my tastes, but I'll make an IOM boat though just for the hell of it. Maybe I'll come around to IOM sailing?! 

Take a look at this version built by someone from Poland. Here are others. And I like this one too.

The picture below is of a Laerke built in Poland. This picture is not mine, so please see the link for the real owner and for copyright information. I make no claim to this photo, but really just wanted to show how beautiful this boat is! 



I will make mine very similarly to the one from Poland. In fact, I'll probably try to simply copy it! It really appeals to me. The hull will be western red cedar and the cockpit will be Alaskan yellow cedar. Not sure what the foredeck will be yet though... maybe western red cedar too? Maybe 1/32" plywood? Would three woods on the boat be too much?

The plans are available for free online. I've downloaded the DXF file and am now busy making a 3D model so that I can make laser-cut frames. Here's what it looks like so far:


I've only just started working up the frames. You can see Frame 0 and Frame 1 in the picture, but the rest are just shadows so far.

And yes, I'm making it with frames built in! I know it will be way too heavy to race competitively, but as I've already pointed out, the Laerke is an outdated design. Even if I had the lightest, most perfect Laerke in the world, it would still get beat by these modern plasticy, molded things that don't even look like boats. The frames will make it one of the strongest IOM's out that, and it should last decades. It's likely that I won't leave all the frames in place, but several will remain in the hull.

However, if someone ever wanted to, they could use my frames to build a very light shell hull without the frames. You would simply put some plastic tape over the edges of the frames and the planks wouldn't stick. And since there are 19 frames, each only ~2" apart, taken straight from the original CAD files (with the outer skin brought in only 1/16" to account for the wood planks and fiberglass), the hull shape should be virtually perfect.

Full disclosure... I know very little about IOM's. The have weird rules regarding the mast step and many other things. IOM's are raced here in Seattle, so I should probably at least make it class legal in case I ever do wish to race it.

Oh, and I modeled a Hales Double Block too because I needed to align it in the model to get the mainsheet placement correct.



Anyway, that's it for now. More as I get closer to a proper 3D model.

Aloha!

Riptide 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 "Riptide" 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 Riptides 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 squ…

R/C Sailboat Builds

Here are the other boats I've built in the past few years:


1. A Tippecanoe T37. These are kits available from Tippecanoe Boats in Washington State.








2. A classic, wooden, Star 45. It has been officially measured and is class legal. The Star 45 is a pretty, classy, builders boat that has withstood the test of time.







3. A Salish 475. It's my own variation on the Star 45. It was built from the same laser cut frames as the Star with a number of modifications aft of frame 6. It is an update of the classic look and was an attempt to mimic a modern ocean racing yacht.










I've also built four Pygmy kayaks and many other projects. It's all fun... right?!


Aloha!

Sun Wind RC Sailboat 3D Model

One of my current projects is to 3D model Gus Lassel's 1949 "Sun Wind" Vintage Marblehead (VM) sailboat. Apparently it was originally called the "Sun Daze", as in fun sailing on Sundays, according to Adrian Olson whose father had a connection to the original designer. (By the way, check out Adrian's other model yachts too. He does beautiful work!)

Boats back then were free-sailing or vane-sailing. I think this was a free-sailing boat but am not sure. My version will be modified for RC. All I have to go by is an old set of lines, but hopefully I can get a decent model out of it. Eventually I would like to make laser-cut frames from my 3D model and actually recreate the boat in RC.

Adrian Olson offers a modern fiberglass kit for the Sun Wind. The pictures look beautiful! My intention is to create frames so that a builder can make their own wood & fiberglass version. I really doubt that many people will want to go through the effort it can take to make a …

Vintage Marblehead Riptide 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 Riptide 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 Riptide go back to 1949 and are most likely in the public domain. One version of the Riptide 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 Riptide but only…
