my understanding is that L-shape is also better at low speeds as it provides higher lift even though at the expense of more drag - also more forgiving overallMy J/90 keel looked similar, not quite as fat as it had a very high tech fin. J Boats debated the torpedo vs. L shape, and feedback came from many sources that the torpedo is a pain in the ass with kelp etc. getting stuck, needing kelp cutters etc. A slong as you can balance and position the weight correctly underneath the boat, it doesn't matter the shape. Besides, it is not exactly visible below the water line.Love the boat, but man that keel is quite fugly...Seems like J could design a keel that at least looks fast!!
just my 2 cents
