I really liked the 15' half-deck yawl design but I was wondering if it could be bigger. Maybe double it's size. I would like a boat that I could take a couple of family's out sailing for the day. About 8-10 people. This would be a lake boat, nothing bigger then 3 foot waves.

Hi Nick

You can't make No. 055 twice as big – you could stretch her by about 10% or so but after that everything starts to get wrong both structurally and dimensionally.

There aren't many large open boat designs around nowadays – I suppose because there is a rather limited market for a boat like that. Most of the original large open sailing boats were commercial – oyster boats and so on.

There was a thread about this on the wooden boat forum not so long ago:

In practice of course you can take any suitable sailboat of the size you want and simply build it without the cabin – leave the foredeck and the side decks – maybe run the foredeck a bit further aft; maybe change the side decks a little, depending on their existing width.

There would be a few structural modifications needed but probably nothing so very serious.

Thanks for getting back to me. There is a boat out there I like called the e33. I would like to build a cross between that and the 055. I would like a yawl even though it would be slower so I would be able to put up the masts without a crane. Also a kick up rudder and centerboard/keel. so it could be trailered. I have a brother putting together a large cnc router machine so if I can get the files in pxf form I would be starting off well. If you have any ideas that would be great.

We are talking about two incredibly different boats here!

055 is a fairly traditional 15' long half-decker – basically an open boat, with a centreboard. She is really a large dinghy.

The e33 is a very modern, some might think quite extreme, 33' sailboat, with a deep fixed keel and a very modern rig

Both are lovely boats, but they really don't share much in common. Honestly they don't ...

A yawl rig is not necessarily slower and the mizzen is quite small compared to the main – so the reduction in spar height for the mainmast is not significant. Much more significant is the rig – a gaff, or gunter, rig produces a substantially short mainmast. But at some reduction in efficiency. Though with modern sail cloth and fully battened sails, both rigs can be pretty efficient.

I appreciate what you are saying and why you would like – but truly I am not sure it would have enough general appeal to make a design worthwhile.

I do have a design – No. 056 – which does encompass some of what you are thinking about – though that is not very obvious from the study plan! She was immensely successful as a sailboat – performing brilliantly and very seaworthy. But I have never managed to get around to producing the plans for general use.

Thanks for the reply. I did look at the 056 the only problem is that the state I live in trailer laws limit the width to 102 in. or 8.5 feet and that plan looks like it is over 9 feet wide. I do not think I would trust leaving a boat I built out of wood in the water long term.
