Questions

What Aloha 28 parts does MAURIPRO carry?

The Aloha 28 page lists halyards and sheets made up to this boat's rig lengths, mainsail covers, sails, winches, blocks, travelers, genoa cars, boom vangs and spinnaker poles sized with manufacturer guides where the boat size allows. Prices and availability shown are live from our catalogue.

How do I know a part fits my Aloha 28?

Halyards and sheets are made up to lengths computed from the Aloha 28's published rig dimensions (I, J, P, E). Other parts are matched with manufacturer sizing guides and are labelled as sized for this boat. Fit can still depend on your boat's year, builder and rig, so check the product details or ask our technical team before you order.

Where can I find the Aloha 28 rig dimensions?

Our Aloha 28 Sailboat Data page lists the rig dimensions (I, J, P, E) and other published data we hold for this boat. Figures come from a sailboat database and may differ from your boat as built.
