After much contemplation....I decided to make another plastic hull airboat. This design has been borrowed from Hooty301 (with blessings) and his legendary, wall climbing "Kamakazee" airboat.
44" long 20" wide and 4" deep. A poulon Wood Shark (36cc) from a previous build will be used for power.

that looks pretty sweet! what sort of plastic are you using, and how are you gluing, adhereing, etc?
Thanks! I get the 1/8" ABS plastic in 4 x 8 sheets from a local company called Regal plastics . cost is around $40. I put it together using Methyl Ethyl Ketone, or MEK for short. It is a solvent normally used in painting (I think) but it melts the ABS quite readily. I also make a paste glue using the MEK and ABS scraps that is used for sealing the joints.
Weight as shown: 22 LBS. hoping to stay right around 25 LBS RTR, which will be about 10 LBS lighter than my last one. It may be heavy...but it's almost bullet proof.

Heck with closing her up ... living up in Onalsaka , that white stuff is soon to hit and stay . Keep her as is for the winter , and THEN modify if needed . ( snow runners are LOTS more fun that running on water - that is soon to be FROZEN )

Check out this cage - made of an old bike rim - aluminum - super light 1 lb at most. ok - Its ugly - but very functional . Ok - it's not really a cage - but a rollbar !

Sweet work!
As far as the floating issue goes, not sure how the extra weight from the cage is going to effect it but I think it should be fine. Id definatly try it first before you close it in.

Thanks guys! I have formulated a plan to keep the cage weight to a minimum. I think 1/4 x 1/4 square and 1/4 x 1/2 Aluminum will be the building material. It'll be much like this other cage, but with only 1 hoop and not as much bracing. BTW the one in the pic is 4 1/2 LBS.

Those must be solid sqare metal rods used to build that. Cuz MAN that seems heavy, does that include the gas tank? Your motor doesn't mount to the cage does it?
