Well you have been busy! You made a good job of the longboat, very tidy.
Remember when ýou plank the big one, to do a little on each side at a time. If you do all one one side in one go, you risk the hull twisting or bending.
That bending tool is good, I have not used one myself but have a mate that does. He says that as long as the planks are wet they will bend very well and the heat, as it drives the moisture out of the wood, sets the bend.
Also if you can find some off cuts of some hard wood, teak or oak make some extra forms to bend around. It can often pay to make some just for the Hull you are building, so you can get the right radius for your curves.
They make a nice little tool for throwing your own ropes as well, should you have problems finding just the right thing to use.
