They cost a great deal, don't sail, are difficult to row, don't tow properly and get stolen. When rubber dinghies have such features why did traditional wooden ones go out of fashion?
I admit that a badly designed pram dinghy is an abomination. It takes a great deal of skill to design a good one, but there are some good ones about. Above is Peigi, a Joel White Nutshell design, which I built in 1986 and she has followed behind Stroma on countless trips since. We don't have room on deck for her, but she tows beautifully and has been through the roughest seas without ever shipping a drop.
Not only does the nutshell row well, you can ship her sailing rig in a few seconds and be off to explore your anchorage. She's incredibly forgiving and stable under sail. Here is our young friend Johan doing well on his first ever sailing trip.
Here I am having a shot.
You won't be able to buy a nutshell in a shop, but making your own is an excellent introduction to boat building. There are only about 20 parts and they can be shaped and put together with the most basic tools, a jig saw and a small block plane being the main ones. The longest parts can be cut from a standard sheet of plywood, but there is a 9 1/2 foot version if you can find the larger sheets or are willing to do scarf joints.
Here is Peigi in the workshop.
Here is a beautiful version Peter made, also about 25 years ago. They last well.
If you're wondering what to do during the rest of the winter why not get a set of plans from Woodenboat and get going? The only disadvantage I can think of is that your next build may be much bigger.
