What about keel shapes and keel-bulb design

Someone asked about shapes and sizes.

I like keels that resemble in some manner the "Scheel Keel". Flat bottoms help fight heeling. My version was based on my sailing in waters with lilies and pond grass that snagged torpedo shaped bulbs. I liked being able to back away and have the crap slide off the keel.

Here is a photo of the original Mainwaring Keel and Mainwaring Bulb

Subject: Re: [Star45] Deck rigging and such

Here is the list on the star 45 yahoo groups for rigging. I am using the following for my next couple of builds:
GBMY item #, description, qty, purpose
019, 3/8' alloy tube, 1, Jib boom
034, Hales single block, 2, main and jib sheets
146, tapered drain plug, 1, plug in transom
182, Z sheet hook, 2, sheet ends/boom attachment
202, large bowsie, 1, back stay/forestay with 80 lb Dacron, order small ones if using spektra
206, O-rings, 1, hold the Z hooks to the boom.
254, double block, 2, main sheet and jib sheet adjuster
255, sheet exit, 1, turning block for main sheet from under deck to above deck.
269, eye plate, 1, mounting for jib block.
272, 180 deg sheet lead, 1, turn around for jib tweaker
280, sheet hook, 1, hooks for backstay and fore stay.
282, tang, 1, attach lowers to mast.
907, rigging screw, 4 hooks, 2 packs, upper and lowers to the deck.

I also build my own chain plates, so I don't order them from GBMY. Don does carry them if you need them. I also like the Ludwig mast better than the bantock mast, so I ordered 8 foot masts cut to 69' from Larry Ludwig, the other 28' or so is the main boom. Last time I made all my own boom vang, mast fitting. This time I ordered them from Larry. You can use the bantock mast, boom, and fittings from GBMY as well. They are good stuff and I have them on my IOM.

The back stay crane is made from 1/16 (.063') aluminum that I bought at the local hobby shop.
