The incident was only the fourth call-out for the volunteer-run BVLS, which organised a successful pounds 120,000 fundraising campaign to replace Blyth's all-weather lifeboat after it was withdrawn by the RNLI two years ago.
BVLS spokesman John Tuttiett said yesterday: "This incident was a good example of the value of having an all-weather lifeboat in Blyth but it was caused by the total and absolute stupidity of whoever cut the trawler adrift.
The BVLS is based in its very own lifeboat HQ, Portakabin buildings on Blyth Quayside, which includes an operations centre, crew changing facilities and a gangway and pontoon leading down to the mooring berth for the lifeboat, Abbie Dean's Spirit of Blyth and Wansbeck.
BVLS officials say it cost the RNLI about pounds 146,000 a year to operate Blyth's all-weather lifeboat, but they plan to manage on between pounds 25,000 and pounds 30,000 because of lower overheads.
operations manager Ian Woodhouse said: "We have 17 crew members trained to give us 24-hour cover and, while we don't want to see people having to be rescued, we are now ready to go when required.

spokesman John Tuttiett said: "We are plodding away quite steadily and the boat will be in service in a matter of weeks.

volunteer Ian Woodhouse said: "Our feeling today is one of sheer elation and a dream come true.
spokesman John Tuttiett said yesterday: "We said we would have a replacement all-weather boat in Blyth by the turn of the year and we have delivered that.
In fact, the combination of the B Class's higher speed and the delay imposed by the unavoidable Blyth harbour transit will mean that casualties three miles off Blyth will be reached in around 10 minutes from launch from Cullercoats and Newbiggin, compared to 20 minutes for the proposed BVLS
rescue boat operating out of Blyth harbour.
For several months members of BVLS
have been in contact with their counterparts in Caister, near Great Yarmouth, who have been running their own independent lifeboat service since the RNLI decided to close the station in 1969.
