Building the Scale Model

Well, it has been a long 2 weeks! I have re-designed the entire boat to able to now hold a 22hp inboard diesel engine, and 3000lbs of diesel fuel. I have Constructed another 1:8 scale model of the new design. Designed and built a wave tank, and had a look at some very primary images of the boat performance in the wave tank. Below are some images of the progress..

The completed scale model.

We have some decals out to a local vinyl printer being created, to bring some life to the scale model. Will make for some great images in the wave tank with a realistic model!

Sealing the urethane foam, and adding structural strength to the model with a coating of Duratec surface primer.

The scale model has been weighted appropriately to have weights of all components in the correct place. Gas tanks, motor, driver etc... All the weights are simulated with nuts and bolts, precisely weighed to match the 1/8th scale proportion for the model. Then all the bolts are encapsulated in expanding foam to ensure they do not come loose during testing.
