When Serenity MF 695 has done this trip , she has 130 Litre tank and I take 3x 20 Litre containers. Poole entrances to Bray harbour is 59.8 nautical. The most she has used one way is 160 litres wreckhopping when fully laden with 3 guys and all their kit, trip took 5 hours. It is good to take some guys to share costs and of course be good company.
