Here's a subject not covered much.
Has anyone built a trolley to convey their craft to the lake.

I have just spent two days building mine to transport my Boston Typhoon. This came about because I weighed her after the testing tank setting up to the waterline and balancing the sideways tilt fully loaded.
The total weight is now 3 stones, (or 42 pounds) and I nearly fell into the pond by lifting her out. The pond is a recent acquisition from Wilkinsons and is featured in the 'Bargains' section.
The trolley comprises a set of Golf trolley wheels and handle, fitted onto a wooden board. Atop this is a standard boat cradle, glued and screwed down. It has it's first coat of paint and when finished, will be padded out to accommodate the boat. I have prevented tipping sideways by struts above the wheels. I don't want it to fall over on the corners.

I know it looks a long beast but the boat is 5 foot long anyhow. The handle folds back and the wheels tuck under the carriage, so it fits into the car with the boat.
Let's see your inventions. :)
