Right got local charity raft race coming up in a couple weeks.
We borrowed local YFCs raft last year and came 4th (but won most original raft!),
The raft was a fair unit made from 25lt drums and wood, fair heavy, the team felt we could do even better with a more sleek craft.
Last year we had 8 team members on a raft based on 36x 25lt chem drums, which is 900kg displacement.
So the requirement is to hold 6 team members incl @itsintheblood @exmoor tom and myself, so far none of the team are big units
. Av weight let's say 90kg so I reckon 600kg team including the theme prop (that's a secret but very light weight).
I've been told to not go over board with what ever supplies the floation otherwise the raft will ride too high....... obviously not enough floation and we sink in the Bristol ditch!
I'm abit limited size wise to my flatbed trailer to get raft to beach on the big day.
So 14ft x 6ft
So my current thinking is either 2x rows of 5 x 120lt blue barrels, so ten in total, = 1200kg displacement.
Or 2x rows of 4x 120lt barrel, 8 in total, 960kg displacement but some loss of space for the team to paddle.
Or 2x rows of 7x 60lt barrel, So 14 in total, 840kg displacement.
I'm thinking all 3 designs held together with Ali scaffold tube and clamps, that way I can break down and change reasonable easily.
I reckon design 3, using 60lt drums would be best as the barrels are only 15" across so nice and sleek, but I'm concerned whether there's enough floation?
Thoughts TFF?
