Our Happy Clients

Your service and hospitality has been greatly appreciated over the years.

You have the best marine facility on the south shore of Lake Ontario.. and you have the bay as well as the lake, so we can sail in most conditions, as one or the other is favored.
Katlynn has the best protected area for boats on Sodus Bay—where you can sail on the bay even if the lake is not good. I’ve been a customer of Sills/Katlynn since 1971.

We had visited Katlynn a couple of times from Irondequoit Bay and found the resident boaters and staff very friendly. That positive impression was key in our decision to move our boat out there.

Katlynn is one of the nicest marinas that we have stayed at. It has great bathrooms and an awesome clubhouse. We have used the picnic pavilion and the new deck with the great lounge chairs. The best thing about Katlynn is that the boaters spend time there and we have formed a tight boating community. Debbie and the staff are very accommodating.
