4 litres of "Metal Gleam is about $46. Will bring the topsides up like new and recover the teak in the cockpit. The gelcoat on the hull looks pretty good and I would pay a shipwrights team to compound that and polish. Take this opportunity to sew up a new stackpack. The saloon cushion looks bad but I could live with that for awhile. Hopefully that is the engine cover in the forward section of the saloon. I'm a real fan of centrally mounted engines now!
If you bought that for 5 grand you will have done well!
A Steal,but saleable - no high water marks inside = dry + just need Metalgleam ?
Sad,as have bays full of boats like this,that are worthless - only gone if sink ? but gulls loving the nesting sites !!
Good project
for years was in a swing mooring just you entered Manly boat harbour and was kept in immaculate condition
Well worth a look

The Yankee is more of a cruising yacht.
Sailboat Data has become difficult to look up yachts. I could not find the Defiance data.

I missed out on a US built SS 30 Yankee once, and I loved the wonderful engine and drive train access. The other good thing was a lead stub keel, bolted-on with bronze bolts. Having seen a shiny 120 year wreck old bronze prop shaft underwater, I have great faith in bronze compared to SS for keel bolts. Don't know if Swarbrick used bronze, but easy to check.
IMHO a good buy if you have the time.

How does this design compare to the Defiance 30
A year or two older but designed to the American CCA Rule, which came before the IOR and allowed for wider and less distorted sterns and narrower overall beam. The Americans rate all the Yankee/S&S 30s quicker than their version of the Defiance/S&S 30 style , with the later Y30s almost as quick as an S&S 34, although that may be different in Australian chop and breeze.
The 30's skippers often claim they are faster downwind than the 34 s . Maybe a longer waterline length??
The Swarbrick 30's keels have stainless studs holding them on.,, With windows cut in the the lead keel to access nuts, same as the 34s ,,
3/4 BSF 12 tpi

That's interesting news from the 30 skippers because it confirms what one would theorise looking at the design. The advantage would probably not be so much the actual waterline length but the wider stern and skinnier, proportionately lighter hull.
