First Restoration - how big a mast ?
« on: April 02, 2013, 01:58:35 am »

Hi All,

So I've started on my first restore of an unknown pond yacht - circa 1930-1950.

I have no sail plan, nor mast dimensions

The Hull is 29.5 " long and maxes out at 8" wide and I need to source a mast for it ...but how long ?

How do I calculate this without a plan ? is there a formula  / rule of thumb ?

Regards

The mast height is not critical unless you aim to race, but obviosly you would like to restore to original as possible.

Do you have a photo of the hull, so that we can try to guess the type of yacht the model is based on? That might throw up a sail plan.

There is also an organisation the Vintage Model Yacht Group http://www.vmyg.org.uk/ , a member there may recognise the model

Hi,
 
A very rough rule of thumb is:
 
1.5 times the boat length
 
However it would be better if you can identify the yacht first.

If it is going to have a bermudan rig, the hull dimensions are just about Victoria size and the mast is 43" long.

Thanks to all for your feedback

it will be a bermudan rig , where individuals have posted mast sizes can you clarify whether this includes
the section of the mast below the deck ? or just from the deck up please ? thanks.

I posted some pictures previously  in the "yachts R&D" section a few weeks ago when I acquired it

linked here:

http://www.modelboatmayhem.co.uk/forum/index.php/topic,42309.0.html

had no feedback so I assumed everyone had drawn a blank ok2

I've emailed the vintage model yacht UK contact . my nearest match is a scaled down 36R
(MY93 on their site - tried to post a link but my browser wont allow me to paste ????? )

Regards

The rough rule of thumb still works! :)
 
44.25" mast would be from the deck.
 
All my Marbleheads are 50 inches long with a 72 inch masts.
 
The tallest sail is 68 inches.
 
Each boat has three sets of sails to be able to sail in most winds.
 
Here in Oz we sail them in the rivers and lakes. Stainless steel rudder shafts are standard.
 
My oldest yacht is 22 years old and still sails.

Hi Bigbloke, I am jealous!  You have a nice Braine steering yacht.  There was a 30 inch class I believe at one time.
Advice so far is good mast about 42 inches above deck and about 400 - 500 square inches of sail.
You can put the Braine steering into working order (google for information) and just have a wire poking out to operate the rudder .
Should look nice.
regards Roy

Hi Roy

thats interesting. everyone with model yacht knowledge I have spoken to has thus far confirmed that there was
never a 30 " class and surmised that my yacht was a "well made toy copy" of a 36R racing class

Is anyone able to shed more light on a 30" class ?

Certainly I can find precious little about the possible source, however, the mum of the lady who's attic it was in
was a yorkshire lass so there is a connection. I never met her father - passed away when she was young sadly
he was involved in motor racing I believe.

I attached the hull with a cabinet scraper which has revealed a nice glossy varnished wooden hull beneath the filler
and the brushed on green paint. I hope I can keep that on display going forward, but not sure if the historic damage
that I uncover will permit it sadly. I know most folks seem to use Isopon P38 filler, but I was wondering about colour coded
"plastic wood" and lashings of fresh lacquer on top to re-seal the hull ?

time will tell I guess . complete novice at this restoring game !

regards

Hi,
I don't know about your part of the world but here in Oz I use 'Timber Mate'.
 
It's a water based woodfiller but it can be tinted!
 
I use it for different types and colour of woods.
