  1. Forecast is dropping quickly, as is usually the case. You should still be vigilant, but it seems to be getting more manageable. Lets see what they say in the next update. This is the forecast for BI Sound as of 5pm Wednesday: Thu: E winds 5 to 10 kt...increasing to 10 to 15 kt with gusts up to 25 kt in the afternoon. Seas 3 to 5 ft. Rain. Vsby 1 to 3 nm. Thu Night: E winds 20 to 25 kt with gusts up to 35 kt. Seas 3 to 5 ft. Rain. Vsby 1 to 3 nm. Fri: NE winds 20 to 25 kt...becoming N 15 to 20 kt in the afternoon. Gusts up to 30 kt. Seas 3 to 5 ft. Rain likely. Fri Night: NW winds 5 to 10 kt. Seas 3 to 5 ft.

    Greate! I in love! Over a million others agree with now so far!

    A central rudder ventilating when pushing hard is definitely a problem, and always will be, but one has to be sure that the cure is not worse than the problem. I've also experienced rudder ventilation many times while pushing hard off the wind, but while it can be scary, I have never had a boat round up or spin out from it. Usually it will keep tracking reasonably straight, or start to head up or down, but always gradually, and steering control is usually restored fairly quickly. But having no control can certainly be a concern. The key is to always try to keep the boat/sails well balanced so boat will still track well without a rudder, and to keep the stern sections in the water for as much as possible. This is one reason why I do not like very wide aft sections on floats, as they will lift the stern more, particularly in quartering waves, which means a greater chance of losing control. Float rudders are definitely the ultimate answer, but they do add more expense, more weight, more drag, and more complexity, and will be there for the 90% of time when they are not required. Weight can be reduced by making them smaller, but then one can end up with not enough rudder in other circumstances, to where control will be lost and the boat will end up in irons. However, float rudders are a valid solution, and hence they are optional on the F-85SR and F-32SR, but they would not be my personal choice. The other alternative is to use a much longer daggerboard style rudder blade, with a more effective section, and the F-85SR will have such a rudder as standard. Advantages include simplicity, less weight, lower cost, and while it can be deep when needed, it can also be lifted up when not, so wetted area is less for the 90% of the time where a deep rudder is not necessary. Next step is to add water ballast to stern, so as to keep main hull stern down when required, and a stern ballast tank is standard on the F-85SR and F-32SR, with float sterns tanks optional. This weight again can be got rid of for the 90% of the time when it is not required. The other tactic is to never fly the main hull much at all, or have it just skimming above the water, so that rudder is always kept in the water. This is the fastest point of sailing anyway, as any higher and one is only adding windage and reducing power, while just touching the water or planing on the top is not much slower, if at all. In theory it should be slower, but in practice I doubt if there is much difference at all. We have the same situation with the daggerboard down versus daggerboard up debate when off the wind - daggerboard up should be faster - has to be! But we have never found any difference when comparing identical boats, on long downwind legs, with board up on one, board down on the other. I have instead lost far more time by forgetting to put board back down at leeward marks, so now the board stays down all the time, period. However, I still find myself lifting it on very long downwind legs in important races, just in case, as it just has to be better - right? But I have never seen an instance where it was. So I feel the same about flying center hulls, looks good, but likely no faster, slower if too high, and it increases capsize risk. Just my opinion. A long board will always be better, and the problem with a vertical board on a tri is that it will have to be behind the mast, and get in the way of the boom when raised, plus make it very difficult to lower mast on a trailerable tri. I'm happy to go either way, as it is a 'six of one, half dozen of the other' situation, and I have vertical boards in my F-41 cat design, mainly because it is better for the interior, a little simpler, and there is no boom above to foul. Ian Farrier Farrier Marine Designs that work... Thank you very much for taking the time to answer my questions so completely. It is a rare opportunity to get to talk so candidly with the designer of boats you admire and sail on.

    Float rudders are optional on both F-85SR and F-32SR, which can have squared off float sterns for this purpose (standard on F-85SR). You can in fact see a photo of the first F-32SR rudder float mount in another posting I did today under Seacart 26. But float rudders are a lot of extra cost and complication, and will only be an advantage for around 10% of the time during racing. This makes it hard to justify the extra expense and weight in my opinion, but they are fashionable, and can be fitted if wished...... Hard to steer when folded however. Ian, never thought about the steering when folded part. On the F-Boats I have sailed on we never had the need, but I can see where others would. Also, isn't the 10% of the time float hung rudders are an advantage a very important 10% of the time! In the limited experiance I have had compared to yours, I have had the central rudder ventalate casuing a round up on more than one occation while pushing an F-boat hard. To compare I have also pushed the lightspeed 32, and Stilletto 27 GT catamarans very hard and have never lost control. Am I right in assuming that the rudder being on the the leward cat hull completely in the water, as the rudder on a leward float would, be the differance? Also, how is a long raked dagger board better than a shorter verticle one of the same depth? Not being a wise ass, I am really curious. Thanks

    So close! Now just take away the central rudder and add one to each float ala Seacart and make sure the floats have enough volume to lift the main hull and we are there! A Seacart 26 alternative for those who live lives to complex for an "all out" racer. A kick ass boat for the real world.

    J/111 Goes Sailing...

    I thought I briefly saw the 111 sailing around the American Yacht Club Fall Series this weekend. I was very busy trimming main on our boat and only saw it briefly. It had NZ on it's sails. I looked and did not see it on the scratch sheet or the results. Anyone know what was up?
