Title: Lugger to Lorcha
Post by: Jimmy James on March 07, 2011, 08:31:14 PM
The Lorcha is basically a Europen hull with a Chinese rig It was first developed by the Portuguese in the East Indies as a trading vessel that was cheap to run (Less Crew to handle to rig) and was fast enough to outrun the local pirates  The John Company (British East India Co.) had a look at this handy vessel and at first converted a few schooner hull's found they worked well so they started building hull and Arming them as Patrol craft,  Convoy escorts and as Anti Piracy cruisers for the Bombay Marine the John Company's Private Navy The comversion is ongoing and I will keep the thread going as long as there is any interest

 This is the first set of junk sails  - She sailed extreamly well with this first set and only took seconds to reef (Shorten sail)but I had put to many battens on the Mainsail but this is only a minor ajustment.

Having studded the photos taken by Rob (Club Sec) I'm going to remove 3 battens and reposition 2 others that should make a better looking sail
I shall make a rigging plan at a later date but so far I have replaced the two part masts with 12mm doweling pole maststhe Same hight as the old masts the rigging on these will be a single halyard running from the yard on the head of the sail through a block at the masthead  and down to the starb'd rail just aft of the mast this has a bowser on it to adjust the hight of the sail ( a dummy halyard has been set up on the port side for looks only as its not needed)

Lazy jacks very useful for reducing sail on fore & aft rigs in stead of  having to tie loads of reef points you just lower the sail between two sets of ropes (Like a suspension bridge)and only have to haul in the tack and leech pendants ...  Sorry about the quality of the photos but I can't take a picture for toffee

To answer the question --Yes the masts are taller than the Chinese Junk 's would be ---First she represents my version of a John Company Bombay Anti Piracy Cruiser this means she has to be fast...So shes over rigged  ,,Remember shes a Lorcha not a Junk...I was once told Chinese Junks are evolved from the Bamboo raft while European Vessels have evolved from the Dugout canoe ...the Lorcha is a Hi-bread with a European Hull And a  Junk rig and while they have the same no# crew as a European trader because she needs less men to work the ship that means she has more to Fight the ship which would come as an unpleasant suprise to any pirate who came near to her.
also she's much more heavely armed than any Trader with 8 x18 pounder caronades and a long 9  ( mounted on a training circle0

Hi Jimmy,
A Most interesting Topic. I find the small wooden coastal sailing craft from around the world a facinating subject. Especially those from around the South China Sea. So many different styles, with influences from India and Arabia in the south West, China in the north, the more primitive craft the further east and south with the Portugeses and Dutch European influences.
Magic little craft all of them.
Keep up the good work, you've taught me so much, and I'm sure many others have learned as well
regards
kiwi

Great ship, Mr. James. I, too, learn lots from your posts.

 Glade you liked the thread. Wolfs Head sailed well as a Lorcha. The rig was unusual and it was fun to develop it, and pass on knowage to other people who like to experiment.
  But for me the Lug rig being not quite so sedate to sail is more fun and if well handled is very fast with the clinker hull (no wonder 18 century HM Customs & Excise ordered all clinker built luggers over a certain size to be cut in half and destroyed by fire---They could easily out run the Revenue Cutters which were no slouches under sail ) The power of the lug sail is well demonstrated by a true story in the late 20s on the NW coast of Scotland" The New Fishery Cruiser on the coast unlike the old one had oil (Diesel)engines not steam and had a top speed of 12 knots. She spotted a Scottish Zulu (Fishing Lugger) poaching  and set off after her. The tail goes that the Zulu calmly hauled her nets , set sail and ran the Cruiser over the horizon in 6 hrs she then put into the port of Stornaway, discharged and sold her catch and retired to the pub. when the Cruiser came into port the crew was drunk and there was no fish on the Zulu so they had no proof and had to let her go. (The Zulu must have been sailing 16 to 18 knots - not bad for a 72 foot heavy wooden fishing boat

Thanks for the info Jimmy!

I'm back to working on my shachuan 3 masted junk after close to a 2 year hiatus so seeing these photos of your lazy jack setup have been quite helpful.    :-))
