Grampian 30 Tall Rigs
I was asked how many G30 Tall Rigs were built. Gill Bibby provided this information:
There are no numbers as to how many tall rigs vs. standard ones were built. It was an extra that was placed as the vessels were ordered. The main difference was that the sail shape changed to go higher, as was the mast and boom. The mast was taller and the boom was shorter on the tall rigs. This moved the center of effort in the sail plan to a higher spot. Sails from a tall rig will not fit the short rig. I will have to read the sail plans to be more precise on the actual figures of sail area square footage and center of effort.

High Praise for a Grampian 30
I had “Prospero” built over the 1973–1974 winter in Oakville. She is hull 226. “Prospero” has been successfully sailed single-handed to Bermuda twice, and to California by way of the Panama Canal — from Panama to Newport Beach we were at sea 44 days. This has been a wonderful boat, and has caused me virtually no trouble. The voyages were without problems, other than one knockdown in heavy weather off the coast of Venezuela. She righted herself immediately and we made Cartagena easily. The boat currently sits at The Old Lyme Marina in Connecticut. She looks better than new — she is better than new. I now sail New England. I have thought of going south. I could live on this boat for the rest of my life.
