Well, just back from a really awesome week on the Dart. Sibbing paradise with six days out of seven on the boat and some great trips round to Brixham and the coves beyond Blackpool Sands, 122 nm and 22 hrs on the boat, worked out around 3 litres per hour total.
Aerotec was a hoot in the waves and coped with everything including some horrible confused water - quite a blowy start to the week with wind over tide but yesterday in particular was glorious.
The spray deflector worked well, stopped any upwards splashing and deflected it out the back, stayed on the whole week with just the two cable ties.
One other thing I bought to try out was one of these pads:
extra thick black kneeler handy mat high density closed cell foam | eBay
As a kneeling pad for piloting the SIB a la RNLI Y/D Class style, definitely the best way in the rough stuff - really good value and very thick at 2". Worked great - very handy for padding the Pelicase when used as a seat too.
