Not sure if this helps but you may find it interesting.... https://www.facebook.com/photo.php?v=180802632110063
Go for it All depends upon your risk profile and why you are doing the designing. The fact is that building a boat doesn't make a lot of...
Also Farrier id offering the F22 in varying levels of completion if you want that boat and maybe don't want to start from the very beginning....
2nd hand Farrier plans I believe Farrier sold a lot more plans than were ever actually completed. A lot of people make a start and then give up...
Not sure how this turned into a critique of the 8.5M rule. For this boat what are the actual dimensions? Do we know it wouldn't fit within the...
Hi Lance - looks good - some questions: what materials are you planning to build from Ply/foam/Glass/carbon etc? What sort of float volume are...
OK, what I'm calling a "tower" you are calling a "control arm"? (lets call it a control arm from now on) and it can go up and down by the height...
I've stared at your diagram for a while and am none the wiser unfortunately. Do they actually use a control arm of some sort in the AC45's or are...
Been watching the AC45's they have long dagger boards (maybe 4m), relatively short towers (Maybe 1.8M) to haul them up. The height of the hull is...
Hi Doug Length divided by beam is 8.5/.07 = 12.14% and total displacement of ama is approx 1800kg - weight with crew (with luck) should be...
I'm building a trimaran for the Kiwi 8.5m box rule. Yes the plan is to get the main hull flying - float rudders etc. The floats are I believe...
Building a retractable DSS system is adding the complexity, weight and effort I was hoping to avoid... but yes it would be a good soln but not for...
Yes you put it like that and it does sound silly - but that crew dance is what is already happening as I understand it - they put all the weight...
The problem seems to be you want it in or out of the water but not half way in between. As the tri heats up what is the crew movement regime?...
OK but I would have thought adding to RM (and moving the center of lift forward a bit) when the boat is hard pressed would be a good thing? It...
Thanks for the info guys - I guess that curved foils are probably the rolls royce approach but very hard to make and retrofit (and heavy) and I'm...
Thanks for the replies guys. I suspect what I'm pondering would be closest to the "spoon plates" idea but, correct me if I'm wrong they were more...
There seems a lot of designers going for the banana style lifting foils in the floats. Orma 60's, USA 17, Farrier getting in on the act etc. They...
