Have been PM`d, and awaiting a chat and poss visit to see the boat shed, not that any of them are an hours job, but a squint at the various types of boat may be useful, as would be a discussion over materials, all of which will be loafing in the shed. Unfortunately the BEST material will not be suitable as it needs a big saw to cut it up…….
The brief as stated is quite broad, and although there appears to be a small budget, it is amazing just how much you have to spend on a "cheap" boat.
For instance… making something at home uses materials that happen to be on hand, such as glue, tape, cutty things, sticks, balsa/foam/polystyrene plates…..etc.
As soon as you say….I want to build 10 cheap boats, the costs suddenly escalate. Consider also that you might be doing the activity at a scout hut (for instance), and EVERYTHING you need has to be purchased, and just two tubes of glue may be a fiver… Sticky tape, paper, polystyrene all have to be bought…..also for an hours project, the simple boats are just too easy, and how long does the glue take to dry for several gluing operations?? What about decoration….felt pens and paint all add up.
Obviously there has to be the right vessel out there but its tricky.
I think the boat to be built hinges on what the activity wishes to achieve…just a bit of fun, or an appreciation of why boats work, and how….why a yacht needs a keel and so on.
Funny enough, a common line of conversation opened up when Trevor was round the other day…all the odd small and unmarked motors in my motor box. Why do we keep them?? well…it seems that just such an occasion may have presented itself, AND I have a big bunch of push-on props I will never use, all of which could be donated to the event. AA battery holders WITH on/off switches (I did not know they existed!) are cheap enough on e-bay…..propulsion sorted out.
I dare say Molesey refrigeration centre has any amount of expanded polystyrene from the packing that appliances come in, easy enough to cut to useable size on the bandsaw. Possibly just a couple of balsa packs and 5 min Wilkinson's epoxy needs to be bought to furnish 10 or so boats??
