Wampum VM Ballast Installed and Faired

This week has been busy with life, but I've also been able to get a bit of boat time in.

I've installed the ballast and started the fairing process.

First, I cut the boat free from the building board, and then did a number of float tests with the lead simply pinned in place. Ended up using a bolt cutter to trim off some lead from the aft ends of the ballasts.

Then I installed the lead onto the keel with thickened epoxy. When that dried, I then drilled several 9/64" holes all the way through the two halves. The holes were filled with short pieces of 1/8" stainless steel rod, and then thickened epoxy was piped in with a syringe. The lead is now epoxied and pinned permanently.

Then the fairing started. I'm using a variety of thickeners. For strong adhesion, I used phenolic powder to stick the lead to the keel. I've had good luck with it in the past. It's the reddish stuff you can see. But then I'm experimenting with silica. It's the whitish stuff. It makes a very light filler, and seems to sand easily enough yet still be strong.

Unlike WEST System 410, these other two fillers don't need a coat of epoxy on top of it. I've got some 410 and have used it in a few places, but I'm not convinced it's the best to use. I'm liking the 406/Silica stuff better. My silica is from System Three though.

Here is after the first coat of filler. Pretty rough, but it's only supposed to "fill" stuff. The finer coats come after. 

Here's the second coat after I sanded the first coat. The garboard is starting to get filled and rounded.

I'm two coats of fairing compound into it now, and probably have another two to go. So far it's looking better! By the time I put a coat of Interlux filler on it, it will look like perfectly molded plastic! Then it will be painted and look great.

More later!

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?!

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…

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 …
