Have gone for it with the radio control- - employing a Robbe F14 plus an extra 8 channel module with decoder. So far extra controls are : each monitor (scratch built using brass pipe & sheet) left & right (using Robbe pulley set to give me 270 degrees travel), two Irvine water pumps, (real car) hooter, winch (using gearbox from Maplins) and movement for jib and search light.

I sail at King Lear Lake at Watermead County Park in Wanlip Leicestershire. it sat in my attic for 22 years and 2 years ago I dragged it out and gave it a bit of TLC and started to use it again and it has been ran most weekends for the last 2 years.
I ran this boat virtually all day of the Burton Model Boat Club's Fireboat day in September 2006. it is currently in dry dock having a full de-barnacle and repaint.
The dimensions were taken from a book that highly detailed the building of a real Cat Boat.
The hull is plank-on-frame with epoxy and glass cloth as the final surface. A separate and detachable fin keel was used for sailing of the centerboard model.
Radio controls were a Hitec sail winch [HS-785HB] and one servo for the rudder with a 2 channel JR transmitter.
Copying the book plans, scaling them down, and construction took up the winter of 2006/2007. The model is sailing better than anticipated on a local lake in Langhorne, Pennsylvania.
Because of his basic 'Sedan Cruiser' he designed all the mechanicals and electricals beneath the main cabin floor, including the battery. There was quite a bit of detail put into the main cabin - unfortunately not shown in the photos - including a galley, eating area, furniture and the helmsman's station. The scale is 1" = 1ft.
This hull is plank on frame using 1/8" pine planks. Below the waterline there's epoxy & glass and above there is just epoxy. All the brightwork, cabin housing & decks is natural Cherry with a clear urethane finish.
The power is a Dumas 12VDC motor with a mechanical speed control. The bottom photo shows that he added a 2:1 gearbox to the motor and ran it in reverse to increase the prop RPMs. He also included a constant running fan to cool the motor due to the confinement of the space.
The single propellor is 2" - 2 pitch - 3 bladed bronze. As on all his models he used a 2 channel JR XR2 75 mhz.

I sail at Brentwood in Essex - where you can still run IC boats.
Nice build, I think.
