Hi I am currently building a J class 1934 yacht called the Rainbow. I wanted some advice on how to plank the bow and the stern.
1. In the bow section I have to taper the end of the plank so that they align with the bow but then how do I bend the plank. Or just by nailing it to the bow will help.
2. When the 2 sides of the plank meet at the bow the taper is not identical. How do I make sure both are of same length and meet each other at the correct angle to form a straight bow line.
Thanks

without pics it's very difficult to answer your query,but will have a go. firstly measure from the gunwhales at midway to the start of the keel write down the measurement,next measure the gunwhales at the bow down to the keel.the difference between the two will tell you how much to taper the planking per row of planks.next when fitting planks you need to soak them for 24hours starting with the water warm.you will need some sort of plank bender,an electric soldering iron is quickest.you will need to twist upward towards the bow end of the plank.this is to stop the clinkering effect.hope you understand this,another way of finding out is to google u-tube "planking" their are a few tutotials there.good luck.

BTW I did not know that the planks need to be soaked in water. Is this mandatory and what purpose do they serve. My instruction book does not say anything about this. Please tell me more about soaking the plank.

if you don't need to bend the planks too much then you don't need to soak them. however when you start your victory you will find that you need to soak your planks otherwise they will snap, especially at the stern. i know karl said to soak for 24 hours, but i find that if you soak too long the plank can sometimes absorb too much water and expand like a sponge, then after fitting it can shrink again and leave a gap. like all advice on the forum it's best to try different views and decide whats best for you. the sovereign of the seas magazine shows a great way to bend wood using and old tin can and a candle. you get an empty can, lay it on it's side and put a small candle/nightlight inside the can. you then use the outside of the can to bend your wet planks. Come on you Jimmies

In this case the J class in the bow does not really need too much bending. I am using the glue and then tying a thread tightly for a few minutes to hold the planks in place. Saves me labour of hammering in nails which split the planks or leave a visible hole. My biggest concern is the point where the two tapered planks meet at the bow. I am not getting a straight sharp line. Hoping using sand paper in the end will help me smoothen out these jagged tapers. lohitsa attached the following image(s):
