Re: Running Flat?

Ed Conley
 

Thanks for the sketch, it confirmed my thought that the leading edge should
be rounded not pointed. I have not yet located the Sunfish Bible to
purchase it so I hope your game for a few more questions.

I have been sailing with the boat as I purchased it, i.e. I have not moved
any of the rigging. However, as you and others have been helping me I have
been paying particular attention to some of the pictures and diagrams and
noticed some differences between my set up and others. I would appreciate
your comments on my current set up that I list below:

1. The swivel block is located between the last two sail rings on my lower
boom . In many diagrams and pictures the location on other "Fish" seem to
be somewhere between the 4th and 5th sail rings. I think this causes me to
have a long sheet line and more difficulty re-rigging while on the water
should I loose control of it (yes I've done it).
2. The gooseneck is attached between the 2nd and 3rd sail rings on my lower
boom. I notice that this differs form references where it appears between
the 1st and 2nd ring but closer to the 2nd. Boy I sure could use the extra
head room under the boom when I tack!
3. I have been unable to see any good picture of how the upper boom is
attached to the (forgive me I don't know the proper term) halyard(?) line
that hoists the sail. Particularly between which sail rings.
4. Is the attach point on the stern for the sheet line static or is it on a
block traveler? On my "Fish-clone" I have a braided steel line attached
both port and starboard with a crimped loop in the center to attach the
sheet line, therefore, no block.

Thanks for letting me bug you!

Ed

Ed,

I put a daggerboard sketch in the group FILES section. This board is from
another boat group I belong to and will only serve as a reference, but you
could probably scale it down to work with your boat.
