Maas Boat Sales

At Open Water Rowing Center, we’re very familiar with Maas shells.  We’ve been using these shells in our club program every day since 1985 and have been a dealer for Maas since 1987.  Many of our members have become Maas boat owners themselves. We have 12 Maas shells in use as club boats and we store 85 private shells, the majority of which are Maas shells. These boats have proven themselves over the years in performance, durability and  easy upkeep.

Why buy a shell through Open Water Rowing Center?

Maas Shells

Our prices for new shells are the same as the prices direct from Maas Boat Company, and we offer many helpful extras.

We often have used Maas shells for sale – Aeros, Maas 24s and Flyweights. See list of available shells here.

  • We have plenty of time to spend with you.
  • You can try out Maas shells here, and speak to other Maas owners with years of experience with these shells
  • We can help you to decide which shell is the best for your skill level, storage constraints, water conditions, and other important factors.
  • We can show you how to set-up and maintain your Maas shell in top condition.
  • We also have information about other types of shells, to help you compare them to Maas shells.
  • We can help you refine your open-water rowing technique in these unique shells.

We can assist you with your plans for graphics, if you want to customize your shell.  If you need ideas, we can walk you through our boathouse to illustrate the available colors and design possibilities.

We will rig the shell for you and give you a private, one hour coaching session here at OWRC as part of the shell sale.

We can deliver your shell to you if you live in the local Bay Area, for a reasonable delivery charge.

We’re open every day to answer your questions after you buy your shell.  Got problems with technique?  Not sure if you should change the rigging? Call  us.

If you are interested in trying out the Maas shells, call and schedule a time to come in.  You’re welcome to drop in at any time, but we’ll be able to spend the most time with you if we know when you’re coming.
