Re: Stus-List 35 modified keel

[Allen Miles via CnC-List]

Just an observation and maybe not relevant for a C&C 35.

I have a C&C 30-2 with a shoal keel, my close friend Richard Stoltenhoff had a sister ship SeaCure with the deep keel,  Both boats were race equipped white sail boats. I've sailed both boats and they were well matched in the winds we had on LI Sound.  

When Richard moved south to the Albemarle Sound (20 foot average depth where we sail, but tight 6' entrance to the creek and docks), he had his keel shortened and a Mars Metal bulb applied. We raced his boat after my admiral decided she didn't want her boat dinged by "ignorant" racers. Although SeaCure remained fast and retained her stability with the bulb, we had great difficulty fetching marks.  She just wouldn't point as high as Septima and the extra tacks or overstands just killed us.

After Septima was hit by a lightening strike, I had her short hauled and ironically she was placed adjacent to SeaCure on the hard.  I looked at both keel stubs and they seemed to my eye to be identical.  My lead keel portion however had significant additional longitudinal area.  His deep mounted bulb was offset by my wing and stability was very similar.  My lateral resistance though was much greater and we could climb our way to a mark without pinching.

Interestingly enough I've just written an article on Mars Metal for the next issue of Professiomal Boatbuilder Magazine. Their ability to provide not only a bolt on two piece bulb but the design service to recommend the weight of bulb to achieve the same sailing stability as the deep draft keel is discussed in the article. It has been a very successful program for the company.

I'm sure you've all seen this, I often accidentally delete list emails without reading them, anyway, an interesting keel mod:
