I have been in an around R/C hobby for more years than I really care to mention. Back about 15 yrs or so I started building a R/C Sub but having too many irons in the fire it got put away. For the last 8yr or so I have been totally devoted to flying R/C Airplanes. After looking thru this forum on boats and scale ships I think I am going to go back to some of my younger days in the US Navy. In 1972 I was assigned to a unit in Patuxent River, Md. where the newest concept of high speed ships were to be tested. I was assiged to the SES 100B which was built by Bell Aerospace in Chef Menture, La right on Lake Pocatrain. (sp?) In 1974 the SES100B picked up the world speed recorde in St Andrews Bay, Panama City Fl at just over 110 kts. The SES was built on a twin hull design with flexiable bow and stearn seals, powered by three 4500 gas trubine engines for lift fans and three 6000 hp gas turbine engines for propultion, fed thru 13 transmissions to high speed super caviating props. Only question I have for myself is how large to make it, I know that in the R/C Aircraft there are size limits in weight but are there any limits on R/C Boats that need to be addressed.

Wow this looks like an intresting project as for limitations if it were me i would look to see how i was going to power it then work from there only other limitation is size of your local lake

I would hit these guys up for more on the how to http://rc-hovercrafts.com/phpBB2/index.php
If there aren't enough people posting there, I am sure that everyone here will do what they can to help out.

Weight is always something to be concerned about in all aspects of RC modeling.
The lighter you make your boat, the more room you have for batteries if nothing else.
Most people I know limit their model size on what they can transport. Twelve feet is the current limit... And that's if you have trailer.

Thanks for the link and info. Transporting will not be a major problem and have a rather large lake just a few miles from home and two rivers within 1 mile. Wish now I still had all the tech drawing that Bell Aerospace gave us while going to their schools. Picture is taken from old 8mm film. Close to four years in the project and this is all I have left to show of it.

This thread might be helpful also.

Takahashi's english is not very good, but the pictures alone might help a lot. Especially the one that shows the two squirrel cage fans belt driven off of a single motor for the lift.

Thanks for the link, his boat is built very close to the SES I was assigned to. He is using a waterjet that was used in the SES100A that was built by AeroJet in Tacoma, Washinton. Now I really am going to have to go to work.
