This is a crew of amateur enthusiasts with no sponsorship, no shore support (and no professional publicity!); they are all members of the British Inflatable Boat Owners Association ( BIBOA) which is the National Class Authority for Rigid Inflatable Boats (RIBs), crew member Chris Strickland is the Chairman of BIBOA.
Starting at 19.57hrs on Wednesday 25th July, ran clockwise around mainland Britain, inside Ireland (outside Ireland is a separate record).
Leg 1: Lymington to Bangor in Northern Ireland
A distance of approx 460 NM covered in 13hours 35 mins plus a stop of 47 mins), average speed 34 knots.
Leg 2: Bangor to Peterhead
A distance of approx 480NM covered in 11hrs 58 mins (plus a stop of 20 mins), average speed 40 knots.
Leg 3: Peterhead to Lymington
A distance of approx 570NM covered in 16hours 14 mins, average speed 35 knots.
Total time (including stops) of 42hrs 54mins 25secs, average speed approx 35 knots.
Mechanical and other detail:
The diesel fuel capacity was 120galls plus a deck tank of 70galls. Weight of Hot Lemon for the Record run was approx 3600kg.
In order to reduce loadings caused by the weight of extra fuel, the crew used smaller 24"propellers rather than the usual 26"; this restricted the average speed over the Record run to 32 knots (37mph) with a top speed of 42 knots (48 mph).
The engine was a single, standard production Yanmar marine diesel (model 6LYM-STZE) of 4200cc developing 300hp and 700nm torque from the UK importers EP Barrus.
The drive train was a standard Mercury Bravo 3X twin propeller outdrive leg using a set of 24" Quicksilver propellers balanced and prepared by Propeller Revolutions, Poole.
A single Lowrance Global Map 2000 GPS plus a handheld backup, magnetic compass, Raytheon radar and reflector, Icom VHF radio with twin high impedance long range antennae. A full set of Admiralty charts was also carried together with an approved liferaft.
Prior to the Record run, Hot Lemon was inspected by a scrutineer from the Royal Yachting Association, the amateur crew have extensive offshore experience and radio contact was maintained with each successive Coastguard area throughout the run. Each crew member had a personal locator beacon and flares, a main EPIRB and flares were also carried.
Mike is co-owner of hotRIBs.com so I expect he will save the juicy details for his own site (although it would be great to read more about it here!).
It looks like the 3X leg has solved the problems associated with the Yanmar 300 though
