Great stuff, a really great bit of very neat deck planking, and a beautiful paint job on the hull in my favourite shade of green. Regards, Gary.

Wow FAN TAS TICK well done on you maiden sale what a lovely sight hope you have more thanks for letting us all share your venture regards peter l ⛵⛵⛵

Hi Roger A1.

Regarding this statement:
"Air has to travel further around the back of the front this means it travels faster. Faster means low pressure on the back and high pressure on the front."
I sent you a private message.



For everyone I say this:

You are right to look for an ideal curvature for your sails but think about the wing lift formula.
Considering only the factors that can be modified (certainly not the density of the air), it is clear that the surface area and the wing coefficient influence in a linear manner while the speed influences in an exponential manner.
In reality we can't even act on the speed (which is that of the wind) but just hope that there are enough knots.
I have seen sails that looked like sheets hanging out in the sun and still managed to sail even in clause hauled.
This is not to say that structuring a sail in the best possible way is not important, but what is most important is the wind.
My intent is not to criticize anyone's comments but only to reassure Rogal who did an excellent job with both the model and the sails.

She looks great on the water Roger, ballast looks spot on. I look forward to seeing her heeling over under a bit of a breeze. Did I detect a bit of power at the beginning of the video to give her a kick-start?

Rogal 118
Looking forward to see it after finishing thé New colours on thé hull

Hi there Hermank. It is my next refurb project a 1/12 th scale Tyne lifeboat, purchased from a club member last summer. It sails very smoothly and quietly and works well, it just needs a coat of paint and all the fiddly bits adding to the deck and super structure. Should’nt take long I’ve started to refurb the crew that came with it.i will keep everyone posted as I progress

Rival 118 morning
Very very Nice yacht and well built.
When i lokker at it i saw à Rnli model in the background. Which one havé you Made?

Hi andy1 I’ve sent a private message to you, if I can help. In any way PM. Me back, the members on this site have been brilliant with their help and advice, it’s been 8 weeks since I started the refurb of IngaIV and now she is complete. I could not have done it without the help, advice, photos, plans, knowledge and expertise of these wonderful worldwide bunch of guys on this brilliant Model boat web site. Photos are start and finish, Give yourselves a round of applause guys, and once again Thankyou all. Roger.⛵

Hi guys I have an Inga IV to rig, does anyone have details of sail shape,camber jig manufacturer, masts, booms, I only have the boat to renovate it's seen some damage over the years.
Also have an Atlantis the same deal hull, cabins, ballast weight and drop down motor. so I could do with some instructions plans to help me get these done and sailing.any help and pointers would be great

Caber in a sail is what it makes it start to act like an airplane wing. It can be achieved by moving the back corner of the sail to form a curved gap between the boom and the foot of the sail. Movement are only very small as a starting point I would aim to 15mm to 25 mm between the boom and the sail at the mid position.
As said it works like an air plane wing. Air has to travel further around the back of the front this means it travels faster. Faster means low pressure on the back and high pressure on the front.
More camber means more drive at the expense of being able to sail code to the wind too much and tacking becomes difficult, I wouldn’t put quite as much in the small sail at the back. It’s about trial and error. Hope this helps.
Also the angle of the booms relative to the center line has an effect when sails pulled right in.The job should be further out than the mainsail to allow the air to flow round the back of the main.
The main boom should be off center by a few degrees.
