A tax break designed to entice the owners of giant yachts to get their boats retrofitted and repaired in Savannah glided through the Georgia House in February, but it is facing much choppier waters in the Senate.

The Senate Finance Committee narrowly approved House Bill 125 this week and some top Senate Republicans, including Senate Majority Leader Bill Cowsert, R-Athens, are opposing it.

Under the legislation by state Rep. Ron Stephens, R-Savannah, a boat owner would have to spend more than $500,000 on a retrofit, repair or maintenance job before getting any break on sales taxes on parts, engines or equipment. The bill is designed to create a new big-boat repair and retrofitting business along Georgia's coast.
