    Default UH-14P - and ride height / suitablity in open water

    Hi All



    I've been looking at the UH-14P http://www.hovercraft.com/content/in...in_page=index& amp;cPath=34_48 So far it's the best one I can see for the fact that it's 1 engine, 1 lift fan and 1 thrust propellor.



    My concerns are the pointy front end and the clearance of 8 inches. For a 14.5 by 6.75 foot craft is 8 inches enough? Is there any way of increasing this - maybe by making the skirt bigger and having more lift? Would this have implications on stability?



    My post on the feasibility of hovercrafting to work gives a link to the area - I'm told that there are big waves from time to time - and there is a 5-6" grass tuft to mount at the top of the beach!



    A smaller version (the 13) is shown being constructed here: http://www.geocities.com/hoversite2003/





    Does anyone have one of these in the uk?



    Thanks

    The UH craft are well designed and enjoy a great reputation here in the USA. However I've never owned on myself. The point at the front as I understand it may pierce large waves, sending water into the bow mounted lift fan. However I've read stories of the designer Bob Windt taking his craft down the Mississippi over the large wakes caused by barges and tankers with no problem. Once he even ended up on the Detroit River, known for whipping up some waves with attitude as part of a long trek.



    There is another homebuilt USA design by Sevtec, one was constructed in the UK. From what I understand the owner says it does everything it claims. It takes on large waves, has great obstacle clearance, and does it all with very low HP. It has good fuel efficiency and is pretty quite too.



    EDIT:

    Attempts to add ride height to the UH craft are strongly discouraged.

    Look at John Robertsons site:



    http://www.hovercruiser.org.uk/



    He has built both UH and SevTecs in the UK, theres lots of info there.



    Just for yuks, here's the first flight (well sort of!!!) of my Surveyor - taken this afternoon! Still a fair bit to do before it flies for real, though.

    I've got a new UH 13PT hull going cheap if you want one.
