Does anyone know how the leeboards for larger, 30-40' , boats were rigged;
bolt,chain or rope for the povit point? Or a source for such hardware?
Thanks , steve

See the leeboards thread in Building & Repair.
As for your question, we'll need more info -- what design / nationality / era of 30-40' boat? As stated, the answers would be:
1. Yes, all of the above.
2. Any chandelry.

Looks like Phil Bolger is your man. Check out the Yahoo group on Bolger and you will likely get swamped with info on leeboards and attachment.
I ran out of Bolger books at 16 designs and I know there are several more 'Dovekie & Shearwater". He has a sizable number of larger/offshore leeboarders.
The Herreshoff hinge would probably require you have one of the many marine bronze foundries make you the parts but I suspect that the Bolger method is not as pretty/classy/elegant but can be fabricated/repaired and is much easier/cheaper.
Sensible Cruising Designs: Medowlark and Goldenball are leeboard vessels and the construction is DETAILED in the book. Both use an eyebolt that is free to pivot and a pin through the eye is strapped to the top of the board. This allows the board to pivot up and down in what you would think of as it's normal positions and also to flop outboard or "broken wing" when it is on the leeward side.
Bolger has done a lot of lee boards : (paraphrase PB: I am more comfortable with leeboards that can broken wing)
Small Boats: Quickstep 20' (dagger-leeboards) / Fieldmouse 8' (rope) /
Open Mind: Offshore leeboarder 39' (?) / catboat 22' (?) / Volunteer 35' (?) / Berengaria 32' (pivots on a plate that is hinged to deck edge) / Whalewatcher 29' (?) / Schuyt Houseboat 29' (looks like Herreshoff method) / Scow Schooner 28' (?) // Japanese beach cruiser 13' (rope) / pirate racer 15' (?)
30-Odd Boats: Appogee 38' (Alum hull, hinge similar to herreshoff) / Lion's Paw 39' (steel hull, hinge similar to Herreshoff) / Skillygalee 29' (?) / Wish II 20' (?) / Eeek 12' (?)
My only experiance with leeboards was when I rigged a canoe for sailing. They worked.
A centerboard trunk can be the 700 pound gorilla in a small boat. Remember the "Riddle of the Sands". Cruthers, or was it Davies, was always banging some part of his anatomy on the GD centerboard trunk.
Knight, who rigged a similiar P and O lifeboat as a small sailing yacht, used leeboards. Knight, the author of "Small Boat Sailing" and the "Alert in the Baltic" was the inspiration for "The Riddle of the Sands".
