Hi, I have a Hartley 18 too..which I have to admit to not having sailed yet.. and it has winches mounted on the coamings which are wide. So I have read this discussion with interest. I will have to study the sheat angle.
My Hartley is very well built, and seems to have a lot of innovations which would probably keep it out of class racing. It has a ballasted keel, 1 inch steel with lead somehow bonded on. It also has a fully battened main..with sail slugs. I'm not sure whether it should have extra internal ballast as well as the keel. Have to see how it feels sailing I guess.
Do you have the regulation internal ballast?
The Hartleys do not seem to have kept the popularity in NZ that they seem to have in Oz. Ian
Winches on the coaming are probably the most common set-up in the earlier designs and if it's anything like the boats here, your sheeting angle will be fine. My issue is that, for reasons best known to the builder decades ago, I don't have wide coamings like you do and it's not an option for me to fit them.
A fully-battened main is fine - many of the top racing boats here have them and allowable under the rules - and I don't think anyone would be too upset by your keel, so long as it was the correct dimensions. Download the lastest Measurement Form
and see how your boat stacks up.
Internal Ballast: No, I don't have the regulation ballast and a few others in the club have pulled theirs out which is allowable if your keel and boat weight is above minimum (which, by the sound of it, yours is). I don't have the regulation buoyancy foam either - opps!!
Ian, do feel free to send us a photo of your boat. There aren't many from NZ, but the Hartley 18-21 Association would love to hear from you and help out in any way they can.
