vaavud sleipnir

[no, I haven’t forgotten how to write in English.] 

this is a post about a neat gizmo for measuring wind speed using a smart phone.  there are often times when I’m standing on the beach, thinking about – or getting ready to go out sailing my Sunfish, and I’ve wondered what the wind speed currently is. I’m not well versed enough in the Beaufort wind scale to estimate wind speeds accurately myself, so gadgets that do it for me are always appealing.

I currently have an app on my iPhone called Wind Meter – which is pretty neat, but I’m always skeptical that my case might interfere with the results, or just that the speaker/microphone on the iPhone is partially blocked by dust, etc.


and there are certainly dedicated wind meters, often used by sailing race committees – but that’s another piece of equipment to deal with.

I posted about the Vaavud previously, but here is another promotional video for the latest Vaavud model, the Sleipnir, that now measures both wind speed and direction.  the red model (with 2 cups) is the older model, the Sleipnir is the grey/black model, updated to measure wind direction as well as wind speed.




I’m not getting anything for posting this, nothing free, no extra discount – just thought I’d share a neat product with other sailors.  but as an extra bonus this week, both of the Vaavud wind meters are on sale for 35% off… so maybe it’s a perfect time to get a Christmas gift for that sailor in your life!

harken h150

I was just browsing online for some new rigging to get for the Minifish that I bought in November, and came across a nice little video that Annapolis Performance Sailing just created that talks about the Harken H150 cam cleat and some of the accessories you can pair with the H150.

the H150 is a great little cam cleat that I have used before with my Sunfish if I want the option to cleat the mainsheet.  my setup includes a Harken carbo ratcheting block – the 57mm H2135 on a stand-up spring – that controls the tension on the mainsheet.  I mounted the H150 cam cleat on the turned down lip around the cockpit of the Sunfish.  the picture below is before I installed the stand-up spring, but shows the H150 mounted on the cockpit lip.


this position is important for a few reasons: it keeps the cam cleat mostly out of the way, and it makes it fairly difficult to reach that far into the middle of the boat to cleat off the mainsheet when you are hiked out in a stiff breeze.  some sailors/racers like to install a cleat on each side of the cockpit near the outer edge of the Sunfish, but these can hurt your legs if you ever are hiked out and forward enough that they get in the way.

the reason to avoid cleating off your mainsheet in a medium to high strength winds is that you lose the ability to quickly spill the sails if you are hit with a quick puff of breeze.  it is recommended to learn to sail with the mainsheet always in your hand, controlling the sail and making minor adjustments with the wind.  if you were hit with a large gust of wind with the mainsheet cleated, it could cause you to flip your Sunfish and take an impromptu swim!

a note for newer Sunfish with the rolled gunwales – the cockpit trim makes it difficult to install the H150 on the cockpit lip.  you might be able to figure something out, but with my newer Sunfish, I just installed the H2135 and the standup spring, and skipped the cam cleat.  either option works!

APS spring tune-up & boat sale

this Saturday, April 14th, if you are in the area, Annapolis Performance Sailing (APS) will be hosting their 1st annual Spring Tune-up & Boat Sale.

I’ve had good experiences with APS shopping online, and am sure that shopping at the actual store would be just as good.  if you’re in Annapolis, it might be worth stopping by to take advantage of their sale prices on rigging and new boats, or just to watch some of the demonstrations throughout the course of the day.

upgrading Sunfish lines

if you are in the market for new lines for your Sunfish, there are a plethora of options to choose from at the various Sunfish parts suppliers, as well as by calling your local sail shop, or even going down to the nearest hardware store to find some cheap line.

while the hardware store line is probably your cheapest option, the difficulty is usually that any line you find there will most likely not be low-stretch line, and the line could also absorb water when you are sailing – making it heavier and harder to handle.  neither of those things are deal-breakers for a recreational sailor, but your time of the water will probably be improved by getting sailing line instead.

the Sunfish manufacturer, Laser Performance, has some “official” line kits available at Sunfish dealers.  there is both a recreational ($83) and pro level ($134!) line kits that come with all the lines you could want and need, all pre-cut to the proper length and with the optimized line type for each line use on the Sunfish.  these “official” line kits are rather expensive, though, and there are some better and cheaper options out there.

there is also the Sunfish “Tune-a-Fish Kit“, which includes the standard lines for your Sunfish, but also a hiking strap, plastic sail clips, and a tiller extension universal… all packaged in a cute little cooler with a Sunfish logo.  the kit comes in at a pretty steep $130, though.

Sunfish Tune-A-Fish kit

Annapolis Performance Sailing (APS) also has their own custom line kits: a pro/racing line kit ($~95) and a recreational line kit ($~45).  the recreational line package is a pretty good deal — I actually bought this line kit last year – and have been very happy with it.  the APS website also shows the approximate line lengths, diameters, and types of line you might consider for each line if you want to buy them individually.

if you are a purely recreational sailor, though, and have found an older Sunfish to start sailing, you might be better off just buying the line individually.  there are the (2) basic control lines – the mainsheet for adjusting sail trim, and the halyard to raise and lower the sail.  a 3rd line to consider is a piece of shock cord, sometimes called a JC strap – to act as a daggerboard retainer.  this shock cord, if long enough, can also be run from the daggerboard up to the tack of the sail (where the 2 booms meet) and back – this will then double as both a daggerboard retainer, and will also help to hold your sail out when sailing downwind in light air.

Intensity Sails has some pretty inexpensive choices for these lines: the mainsheet is Bzzz Line available in 7mm or 8mm diameters ($25) and the halyard is 24 feet of 5mm line ($20).

a final line choice is if you want to switch away from the plastic sail clips to sail ties.  I bought a small pre-cut kit last year and switched my new Sunfish sail to the sail ties. the colored line on the right-hand side is the outhaul line that connects to the boom end-cap.

for the future, though, for probably both the sail ties and maybe even the outhauls, I am planning to buy this spool of 1.8mm line from Intensity Sails.  at 100-ft of line, it’s probably more than a typical sailor might need, but I don’t mind having enough to switch over several sails to the sail ties. the 100-ft spool should be enough for 3 full Sunfish sails.

I also went into detail on how I set up my new Sunfish sail (w/pictures).

sunfish wind indicators

as part of my new Sunfish sail set-up that I described a while ago, I mentioned that I had added (3) sets of tell-tales.  the tell-tales are positioned on the sail to help give an idea of how the wind is flowing along the sail, and can give you an idea of how the sail should be trimmed to achieve an optimum air flow.  in addition to adding tell-tales to your sail, there are (2) other methods frequently used on Sunfish to help read how the wind is moving on the water.

one option is a masthead fly, which in the case of a Sunfish, will probably be more effective if it is mounted at the highest point up on the upper spar (and not down lower off the top of the mast).  the masthead fly or wind indicator will be useful for sailing downwind, and will give you an indication of how the wind is shifting, and whether you should jibe. (I haven’t tried anything yet in this department.)

the other option is a wind indicator that is often placed at about eye level and frequently mounted off the upper spar.  the wind indicator here is nice because it will give you an idea of how the wind is puffing and shifting, and can be very helpful for light wind sailing.  there are several commercially available options for wind indicators (APS sells a few, Intensity Sails does too).

the C-Vane for Sunfish is about $30 to $35.

there is also the Kingfisher 200 for $15 to $20.


I had almost purchased one of those options a while back, but a weekend or two ago, I decided to initially try to create my own wind indicator to mount down at eye level, more or less following the procedure suggested by this pictorial at Windline Sails.  all you need is a coat hanger to bend into a v-shape, and an old cassette tape to cut up to make small streamers.  so I bent up a hanger into a large V-shape, with little drops at the tips of the V to tie the strands of cassette tape to.   I differed slightly from that pictorial, though, in that I didn’t want to mount the coat hanger wind indicator to the upper spar using only duct tape.

my solution (I vaguely recall it mentioned on the Sunfish Forum, so I won’t take credit for the idea) was to take a small piece of 1 1/2″ diameter PVC pipe, maybe 3″ or 4″ long, and cut it into a C-shape.  it took a little trial-and-error to get it just right, but now this C-shaped length of pipe would slip onto the upper spar of my Sunfish sail, and fit snugly enough to not slide up and down the spar, or twist side-to-side… but it is still easy to pull off at the end of a sailing session.  I then drilled a hole to fit the bent section of coat hanger, and screwed the hanger in place (and filed down the tip of the screw that went through the PVC). so this is a view of the back of my home-made indicator, looking at the C-shaped piece of PVC that will “clamp” to the upper spar.

here is a picture of it mounted on the upper spar of the Sunfish sail.  I have it mounted fairly low – you could mount it higher, but I found I can leave it mounted there, and still raise and lower the sail easily without having to move where the clamp is located.  and as usual, anytime I’m fiddling with the boat in the driveway, my 3-yr old climbs aboard saying, “let’s go sailing, Dad!”

the coat hanger wire is hard to get really straight, so it isn’t exactly a thing of beauty.  I made a very small loop/twist at the bottom of the 2″ drop – that’s where I tied a 10″ or 12″ long piece of cassette tape.  the cassette tape is pretty flimsy stuff, so I’ll probably just throw the destroyed cassette into my box of sailing gear, so I’ll always have extra tape to make repairs.  I have seen comments that the cassette tape can be too shifty and show wind too light to really sail in, so another option if you don’t have an old cassette tape is to just use a piece of yarn or something similar.

my 1st time sailing with the homemade wind indicator was 2 weekends ago when I sailed on Lake Erie with my boys.  I was very impressed – it was excellent at showing me the light gusts and puffs of wind, and most importantly, giving me an better idea of the direction of the wind than trying to scan the beach for a fluttering flag or something similar.  once the Sunfish is in motion, you certainly have to take that into account when “reading” the wind indicator, but if you are stalled out in light wind, or barely creeping along in the water, the light cassette tape does a good job of showing you how the wind is shifting, and you might be able to adjust your heading or sail trim, to pick up just a little bit more wind.  I had all the parts necessary to make it lying around, so the bonus here is the only cost for me was the time I spent fiddling around making the wind indicator.

setting up a Sunfish sail

last summer, I bought a new practice race-cut sail from APS for my Sunfish, as well as the recreational line package from APS.  due to a back-order, I didn’t get the new sail until late in the summer, so I didn’t bother trying to use it, or even install it on my spars until this spring.

a few months ago, I posted about making a custom Sunfish logo for my new sail and installing sail numbers.  since then I’ve been tweaking and adjusting some things, with a few projects left to go as well to finish it out… but here’s what I’ve done so far.

I used plastic sail clips (like shower curtain rings) to initially get the new sail installed on both the upper and lower spar.  for a few specific locations, though, I switched out the sail clips for sail ties, and tied them around the spars, with just a bit of slack, using a square knot.  I bought a package of (15) sail ties made from 1/8″ dacron line from the Sailboat Garage, and it was recommended to switch to sail ties at the following locations.

(3) ties at the clew or near the outhaul of the sail.  I used an extra sail tie right at the clew of the sail.  the outhaul line (1/8″ Excel Pro) is off the right edge of the picture.

(3) sail ties at the head off the sail, and (2) sail ties near where the halyard attaches to the upper spar.  the line at the head of the sail is 1/8″ Excel Pro and the halyard is 3/16″ Excel Pro line, both from the APS line package.  the (2) sail ties at the halyard will help prevent the sail clips from making the sail bunch up near the mast.

(2) sail ties at the gooseneck area, (1) at the cunningham location – the 1st sail grommet above the tack of the sail, and again I doubled up and used (2) sail ties at the tack on each spar, so (4) total at the tack.  ideally, that would have been a single piece of line wrapped twice at each spar, but since the sail ties I bought were pre-cut to length, I just doubled them up.  at this time, I also measured back from the front of the lower boom (starting at the end of the aluminum), and marked 1″ increments from 16″ to 23″ for setting the gooseneck for various wind conditions.  having it marked really helps take the guess-work out of adjusting the sail.  I bought my adjustable or quick-release gooseneck (a must-have) from Intensity Sails.

I also installed (3) pairs of tell-tales on my sail.  there is a lot of debate on whether the tell-tales are effective on a Sunfish, but I have found them helpful since I installed them – as I pay more attention to them and try to adjust the sail trim correctly.  the location of the tell-tales is also debatable, but I found this picture from the Sunfish Forum helpful, and more or less copied those locations.

so the picture below is my new Sunfish sail, complete with a new Sunfish logo I made and my sail numbers.  this picture was taken prior to installing the sail ties.  you can see where I installed the (3) pairs of sail tell-tales. by the way, having a sail with a window makes it so much more comfortable on my neck while sailing, so I’d highly recommend the window for any future sail purchase.

for someone starting out, I would probably recommend avoiding the plastic sail clips, and just using the sail ties for all of the grommets on the sail.  the plastic sail clips are a pain to remove once installed, and the sail ties are pretty easy to tie on once you get started on it.  I’ll probably buy this 100-ft spool of 1.8mm line from Intensity Sails and swap out my sail clips on this sail, as well as my others.  the 100-ft spool should be enough for 3 full Sunfish sails.

my next project is to install the outhaul and cunningham cleats on the lower boom to help me shape the sail – I’ve bought the aluminum cleats and line (in a kit, actually), but haven’t installed them yet, so I’ll cover that in a future post.
