    High School Why would sailboat racers prefer a full keel over a fin keel?

    Yes. Mine is a 26X. The 26M's sibling abomination.

    High School Why would sailboat racers prefer a full keel over a fin keel?

    As I understand it, that is the purpose of the PHRF rating (Performance Handicap Racing Fleet). It is meant to subtract out the advantage and disadvantages of a particular boat type. (hull, sails, etc.) so that what is (ideally) rated is the skill of the skipper and crew.

    Sure, so which keel do they choose? To my eye, their millon dollar keels are shaped like hyper surfaces or Klein bottles, amirite?

    No argument fin feels being nore nimble overall. This question is specifically about why full keels would suffer greater leeway.

    High School Why would sailboat racers prefer a full keel over a fin keel?

    Yeah, I mean, I guess that's part of the problem. Sailors are notorious for relying on unwritten lore and "sea smarts", so it's particularly difficult to find much in the way of fact-based information. If you ask, you'll be told "centuries of experts say so".

    Thats an excellent analysis, Bal, especially the delta wing concept. But does it answer the primary question? Why would a full keel be prone to leeway?

    High School Why would sailboat racers prefer a full keel over a fin keel?

    Full/reef is long, fin is short (longitudinally - i.e. front-to-back). The fin keel is not necessarily deeper than the full/reef keel: Both have zero camber (i.e. symmetrical), of course, since they need to work on both tacks. They generate lift that opposes the force of wind. That's what...

    Undergrad What is matter?

    Right. That's why I originally proposed it in the older thread before being corrected. Still, is it safe to say that - with some exceptions, anything fermionic can be described as matter because of its predilection for taking up room?
