START WITH YOUR BOAT

Choosing mainsails

A mainsail works with the mast, boom, attachments and reefing system. Bring the existing sail’s history and handling issues to the loft. The proposal should explain how the new sail will be hoisted, reduced, lowered and stowed on your actual boat.

MARINEBRANDS FIELD GUIDE3 MIN READ · 3 CHAPTERS

Understand it.
Choose with purpose.

Understand the sail, its shape and the system used to handle it.

CHAPTER 01

Know the parts you are discussing

The mainsail’s leading edge is the luff, the trailing edge the leech and the lower edge the foot. These terms help you describe a problem to the loft: difficulty at the mast attachment is different from wear along the foot. Identify the corners and attachment arrangement with the sailmaker rather than relying on a photograph of a similar boat.

The existing sail is useful evidence, but it is not automatically a reliable template for its replacement. Ask the loft which measurements it will take or verify on the actual rig.

CHAPTER 02

Treat reefing and stowage as design inputs

Explain how the sail is hoisted, reduced and put away, and who performs those tasks. Battens, mast hardware, covers and reefing details should be discussed together. Doyle’s mainsail reference offers examples of options; your loft should explain which arrangement suits the boat.

Describe the difficult moment in an ordinary sailing day. Is it hoisting, managing the lowered sail, or handling it with a small crew? A clear description lets the loft address the problem instead of simply reproducing the old specification.

CHAPTER 03

Agree how the finished sail will be checked

Ask for a fitting appointment and explanation of the intended handling arrangement. Record which fittings and finishing details are supplied and which are retained. Compare quotations using the same headings so differences remain visible.

After delivery, use the loft’s care and handling instructions. Keep observations about fit and operation for the follow-up conversation. The first useful outcome is a sail the crew can manage and understand, with a documented route for service.

MAKE THE DISTINCTIONS

Compare the approaches

Use these differences to frame a conversation. This is a comparison of project approaches, not a ranking of brands.

Mainsails: approaches and considerations
ApproachWhen to consider itWhat to resolve
Conventional mainsail projectAn existing hoist-and-reef arrangementSpecify battens, attachments and reefing details.
Furling mainsail projectA boat with a compatible furling systemRequire assessment of the exact system and sail requirements.
Handling-focused replacementA crew struggling with everyday sail managementInclude covers and deck equipment in the discussion.
WORKED EXAMPLE · ILLUSTRATIVE SCENARIO

The sail is easy to hoist but hard to put away

An owner wants to replace a main because stowing it has become a chore.

A considered approach

Show the loft the current process and ask for a proposal that addresses stowage as well as sail construction.

The brief should cover the whole sailing day.

AVOID THE FALSE STARTS

Two mistakes worth avoiding

01

Leaving mast hardware out of the quote

Specify whether slides, cars or other attachments are supplied or reused.

02

Copying old measurements without checking

Agree who verifies the rig and final fit.

StackPack

Doyle traces the first StackPacks to Robbie Doyle in 1989. The system combines a fully battened mainsail, lazyjacks and an integrated cover to gather and protect the lowered sail.

Official product information ↗

Discuss your existing mainsail, boom, reefing arrangement and cover dimensions with the loft. An existing sail may be suitable as a base after assessment.

Useful answers

Frequently asked questions

Can I use the old sail as the only specification?

Treat it as a reference. The loft should determine what needs to be measured or checked on the actual boat.

Should the cover be included in the sail discussion?

Yes. Explain how the sail will be lowered and stored so the sail, attachments and cover work as a coherent arrangement.

Who should verify the final measurements?

Agree responsibility with the loft before ordering. Photos and old measurements can support an enquiry, but the final measuring and sign-off process should be explicit.

Where can I buy mainsails in Australia?

Use the official contact and dealer routes in the linked brand profiles. Confirm that the supplier supports your exact model and location, and request an itemised quote. MarineBrands does not sell equipment or show live stock.
