Aug 24, 2008 · yipster designer. keel in my dictionairy gives: push over, making capsize, it also mentions coal and the amount of it in a barge, on an even keel means level, in balance, without effort, steady, quiet. i was thinking it was more like: bottom, blade, wing or even rudder. beeing a draftsman al my live i now looked "draft" up in the dictionaity ...
Aug 9, 2008 · The hull design was originally developed for a 404km race that I did a couple of times. The design condition is 12kph at 150W. Once you encumber the boat with the weight and complexity of a flywheel system the speed will drop off considerably. So it is a long distance cruiser for relatively sheltered water.
Nov 6, 2002 · The reference area is whatever you want to define it as - it's typically the planform area for a keel. It doesn't matter if the area is divided up into two narrower surfaces or is one surface. Actually, the best parameter for comparing two keels would be the wetted aspect ratio, which is the depth^2/total wetted area.
Nov 18, 2007 · Her displacement is reasonable at 1,200 pounds and the 650 pounds in ballast represents a 54% ballast to displacement ratio which is quite remarkable in a light, shallow draft (24") fixed keel boat. Because of her shape, she wants to be sailed at 16 to 20 degrees of heel, which increases her LWL up to 16' - 17'.
Stability Guidance by the Water on Deck Criteria. The “water on deck” criteria is used to gauge a fishing vessel’s performance when encountering boarding seas that may become trapped by the vessel’s bulwarks. In this example, Area “A” (in yellow) represents the capsizing forces from the water trapped on deck.
A keel-stepped mast is always stronger than a deck-stepped mast, on the order of +50%, because of the fixity provided by the deck partners. Therefore, if it is inherently stronger, it may also be a slightly smaller cross-section, and therefore lighter, than a deck-stepped mast.
Feb 14, 2016 · There are many chined hulls with compound curved bottoms. A hull made of all developed surfaces is a bit harder to design than a round bottom hull. Usually, it cannot be quite as versatile, but at one design point, it can do very nearly as well. Chined hulls are often a bit heavier than the equivalent round hull.
Jan 26, 2022 · The sailing holiday might be fun.I think Norman Skene must have written his comments about lifting components when his mind was otherwise occupied.If the boat is heeled and a rudder deflection is present,the rudder is likely to produce a lifting component unless lee helm is present.Regardless of the angle of the rudder post to keel,the angle between rudder post and centreline is always going to be zero and all that happens with a raked rudder post is that the moment applied is reduced ...
Jun 5, 2018 · The boat is one meter in length, max sail area allowed is 600sq in divided between main and jib. Max keel depth from the keel line to the bottom of the Bulb is 14.25 in. Back in the day, the general consensus was 32 to 34 sq in. of surface area on the fin from keel line to the top of the bulb. The boats generally compete in winds from 1 to 10 ...
Jun 4, 2014 · PAR Yacht Designer/Builder. The planking lands on a stem or deadwood assembly and is defined with an outer rabbit line, where the planking first hits and the inner corners of this notch (rabbit) called the bearding lines. Most rabbits have a single bearding line, though some can have more than one. This single bearding line is where the corner ...
