Bookings from touring teams are down by 80 per cent on 2011 levels, with the club blaming the sailing spectacle at Weymouth for the drop off.
Touring bowls teams normally bring in vital funds when they visit the area, but the club now faces having to raise more than £2,000 to pay for the loss in revenue, according to club social secretary Christine Neale.
Dave Price of the Weymouth Hoteliers, Guesthouses and Leaseholders Association, said that some hotels have been forced to put up prices during the Olympics because regular customers like bowls teams are not coming.
He said: “There is an impression among the public that Weymouth will be booked up or expensive during the Olympics, so many regular returning customers, like touring bowls teams, are staying away.
The club needs more than £10,000 each year to keep afloat.
Team captain Keith Brooks said other clubs were also suffering because of the Olympic effect.
He said: “Last year we had 10-12 teams visit us. This year it’s down to two or three.
“You tend to rely on touring teams because they bring a lot of people. They pay rink fees and spend money at the bar. You look to make £150-£200 per team who visit.
