Posts: 291 | I have a Hobie 18 that is on steroids. I am running a Tiger mast with a large square top and a self tacking jib. I would like to hear from those who know about foils if there would be an advantage, disadvantage, or no change if my dagger boards were the same shape but a foot or so longer. Would the boat point higher? Would she go slower because of the increased wetted surface.

Getting the board in the right spot is the most difficult part.
kind of slant back, not straight up and down like newer designs.
Finding the proper alignment both left to right and front to rear will not be an easy task and will most likely require some professional guidance.
I will be interested in any ideas or attempts to do this! uhhhh, I don't know what to think after reading this. Is it a sailing question, or some OTHER subject?

Posts: 1,304 Gulf Coast relocated from Cali... | Collin, No offense, your TheMightyHobie18 is definately the nicest one I've ever seen. No matter what, in the end, it will still be a TheMightyHobie18. You gotta decide what you REALLY want that boat to do and how much it will end up costing. You're already pretty close if not past what a good used F18 would cost you. I've sailed around you at the Dike when you were reaching with the wings on it. Your boat speed was about the same as mine for that run. It's a good and fast 18. You may get a couple more degrees going to weather but at what price? If you give a pig a nose job, you'll still end up with pork chops instead of prime rib.

Posts: 266 UK | What you are looking to do is to bring the platform up to the level of the 1980's Hobie 18 Formula 104 by Hobie Cat Europe (pre-tiger). It had high aspect carbon daggerboards and a higher aspect 3 sail rig. Some specs on the SCHRS list. Maybe HC europe can help you out with boards and wells? - if marketing issues don't get in the way. http://www.youtube.com/watch?v=sR8QSlcpre0Cheshirecatman | | | Re: Question about extending centerboards

Posts: 291 | I am actually very happy with how my boat sails. The cost of new daggers from Hobie is more than I what I can have them made for. If I am having them made it would be no big deal to make them a foot or so longer. I was just curious what performance gains or loses there would be. I have to agree with an earlier post that the increased drag would probably out way any increase lift. As for the boat it is what it is. I enjoy tinkering as much as I do sailing. Thats is why I like this platform. It really hasn't been about the money. It has been about the experience. Performance wise the boat is great. In some conditions the F18's and I20 struggle to stay ahead, as proven this last weekend. In other conditions the F18's and I20 wish I would hurry up and finish so that we can get the next race on.
