Mark & Paul, going above and beyond
★★★★★
"We need a prop in a big hurry and Mark and Paul pulled out all the stops to get it to us in record time. Every time I need something it's right first time and on time. It genuinely doesn't get better than specialist small craft"
- Graham -
Propeller replacement in an amazing turn round time.
★★★★★
"On a job in the wilds of Lincolnshire and the workmen on the pontoon hit the propeller on their self-propelled pontoon on rocks and other debris, it was chewed up to less than half the working diameter and one blade was broken in half. A phone call to Specialist Small Craft had a replacement propeller despatched almost immediately and it was with us the following morning. FANTASTIC SERVICE plus the knowledge and experience of the team at Specialist Small Craft is second to none. "
- Simon -
First class team!
★★★★★
"We have been working with Mark over the past couple of decades, Mark and his team have always provided a first class service with a personal touch, we cannot recommend Specialst Smallcraft Highly Enough!"
