Pringle’ (US1m) Prototype Launch.


Recommended Posts

A few weeks ago, saw the launch of ‘Pringle’ (US1m) at Fleetwood. This 3D printed prototype yacht is our entry into this development class and a rare site within the UK. ‘Pringle’, is not to be confused to an International One Meter (IOM), although the yacht has an overall hull length of 1000mm / 39.37 inches, the design has a reduced displacement of 2.75kgs, which is the average weight for this class. ‘Pringle’ employs 4 carbon rigs with the maximum sail area of >387096+ mm* or >600+ sq/inches. Therefore, the whole concept is a lot different in comparison to the IOM. The US1m class is normally only seen within America and Canada, but ‘Pringle’ represent our latest design within our expanding portfolio, which includes entries to specialised development classes across the Atlantic.

The timely launch of ‘Pringle’ came as the news broke from across the Atlantic, the difficult decision was announced, due to the Corona-virus pandemic to cancel the Sacramento Sail Week, which included the class championships with ‘Pringle’ set to compete in the regatta.

As we have a further 12 months of development time, we will take the opportunity to modify further Pringle’s rig and deck layout. I hope to visit Wickham Park, Florida in early January 2021, to test sail this prototype in front of the local class skippers. Should the test be successful, we will produce the first carbon version after returning to the UK and in preparation for the class championships in 2021.

It was nice to read about the launch of John’s new boat.   During the lockdown I had the idea to build a US one metre.   I was fortunate to get a carbon hull made from an American plug.  The boat was launched last week and went extremely well.   It weighs in at 2.6 kg with 1.6 kg of lead.  The physics of this class rule seem ideally suited to our sheltered inland lakes.  I liked the concept of the class ,  it seemed like a mini Marblehead and mine has turned out just so.   The lighter weight makes for much easier launching at my nearest lake where dangling it over a muddy bank is the only way in.    Mine responds very well to our flukey inland winds and is easy to read.   Its ability to carry a relatively tall rig on a light lead was an eye opener.   Like John I’ve gone for shroudless carbon rigs so it’s quick and easy to rig.     The class rules are very simple to work with and straightforward to measure.  Its a class that also takes me back to the days when home building was the norm and now today given the huge progress in materials and construction techniques it’s a rule that still works.    Modern IOMs sometimes have to carry heavy corrector weights to comply with the minimum weight limit which to me seems to defeat the object of starting with a lightweight hull moulding.    I know that this type of restriction is normal for any restricted class but my boat has proved to me what is possible with a smaller development class.   It’ll be nice to hear how John’s boat fares against our American cousins.

Had the pleasure to sail my IOM in company with Tho's US One Metre recently. Very interesting comparison indeed. 

On the water the expected performance differences, as a consequence of the lighter displacement on the same waterline and rig,  results in predictably distinct pro's and con's which probably equalise overall.  A mixed fleet would be extremely interesting.

The rig is a revelation compared to the IOM and so much easier to set up and transport.  Also cheaper.  The rule is far simpler too with measurement very easy.

Really impressed and seriously tempted to follow suit; literally.

Good Afternoon Gents,

Thanks for your correspondence, where are you located Tho? I assumed that my US1m was the only UK based boat. It would be nice to visit you and sail both boats together. After Pringle's launch a few weeks ago it was necessary to alter a few features and adjust the rigs prior to sailing again. I predict we can have my US1m on the water again in 4 weeks from now.  I am located in the Gosport area, but I do travel up and down the country often. It would be a great opportunity to meet in the near future.

 

Regards,

JT

John,

We sailed on Charnworth lake; Loughborough Radio Yacht Club's water. A notoriously fickle water with light/no wind very often. I was sailing  my old, but up dated, Image IOM with an experimental shroudless carbon mast. I am going to "dual rate"the Image as a USOM as another project. The displacement reduction with a 1.6Kg ballast will slightly reduce the WL, but will come onto the 1 metre when heeled anyway. A bit more wetted area / a bit more form stability a bit of fun. The US rule does not appear to ban ballast changing, so when the wind pipes up; use the IOM ballast and fin. Watch the others having to change down. The USOM hull will not carry that much ballast. Downside: light wind performance: maybe.

What are your plans for the US boat ? A real move back to a development class.

Thank you for your comment, the Pringle development has been a 2 year project which involved travelling to the US and sailing these boats. Now I have a prototype US1m of my own, I hope to return to Florida to test sail my boat in January. Once the concept has been proven with other US1m, my intention will be to construct a carbon version of Pringle. 

The plan will be to return to the US later in 2021 for the class championship. Should I achieve a positive result, then the  long term future plan will be to produce my design and make Pringle available for  US class skippers.
