18ft trailerable yacht

Even though you want to desgin your own have a look at the i550 stuff, it is very similar to what you want so you should get a few ideas from it all

yes I have looked at that alot, would you be able to singlehand it easily?
and I am aiming for something in between John Welsford's Sweetpea and the i550.

 

I couldnt tell you, Ive never seen one in the flesh, and easily is a relative term, Ive seen pictures of a Shaw 650 being saled single handed.

The point of the i550 links was so you could answer some of your own questions TTB has a rotating prod that you mentioned, the other option would be a deck mounted retractable prod.

 

yes I got the idea for the rotating prod off TBB, but I can't seem to find a pic anywhere.

 

There are some around, have a sift through the sailing anarchy and you will find the ones you need

 

I have looked through sailing anarchy but with no avail. would anyone be able to post a link with how to make an articulated bowsprit? I have an old windsurfer mast that would probably work quite well.

 

Here is a search of Sportboat Anarchy on the topic.

A quick run through will find several threads talking about just your question.

Thankyou I managed to find pics of TTB, and it is SO stupidly simple, now for a job to build this thing.

 

I will happily take donations though

Jordan, have you considered a square top main? Has tremendous advantages aside from looking cool. And don't hesitate to consider-even on just a theoretical basis- something like Wellbourn's DSS foil. As a budding designer considering the application of new technology can help you learn about design, the technology and broaden the horizons of your thinking. For instance: you mentioned that you might consider putting inside lead ballast on the boat. Did you know that a small DSS foil about 4'(1.23m) long with a chord about the same as a Moth hydrofoil(4.75"/.12m) could provide over 250lb(113.6kg) of righting moment 2'(.61m) from the side of the boat at 7- 8 knots of speed?! And it gets way better the faster you go....Guys like Hugh Wellbourn are approachable and would probably help you as his schedule permits.
Good Luck and practice(carefully) thinking outside the box.....

 

1. A DSS foil would take up the room that is already lacking in the cabin of an 18ft boat
2. It adds unneeded complexity, IMO I think it would be best if this boat could be built by a first time builder, so if the design does work and I decide to sell plans or whatever, it is too hard to do. If it can be built easily by a first time builder it would be much more practical for many people(not too mention me).

with the fathead main, I think this would add too much to the cost of the boat, and I have NO money. I want the boat to be cheap but fast.

 

Just something to think about. Your comments make sense.

 

Yes I like the idea of a DSS foil but for me, and most other people it would be too hard to construct, the foil is the easy bit its all the systems that go with it.
I want to have the boat on the water for approx $7,000

 

There's a few great ways to keep a budget down.

1 - design the boat to take gear off a popular one design;
2 - design the boat to take gear off a popular one design;
3 - design the boat to take gear off a popular one design; and
4 - design the boat to..... you guessed it!

For example, I've got an old Etchells rig on my 28'er. Etchells guys have stacks of sails in almost new condition that they sell for about 1/10 the cost of a new sail. The mast cost a few hundred bucks.

At your size, you may be able to design for a Sharpie or 16 Foot Skiff rig. Then, for example, you can pick up an old 16 for a few hundred bucks and you'll end up with two or three good sets of spars, about 8 sails, good foils, and bucketloads of Harken and Ronstan fittings. And I've seen some guys use the hulls as very nice fishing boats with a small outboard.

 

ok sounds like a plan. I still need a job to do that though.
