Every (modern) Hunter
sailboat has no back stay (B&R rig) with the mainsheet connected to the arch. Not that Hunter's are the best built boat on the planet, but I've never heard of one having the arch ripped off.
Why do most backstays
go through the bimini skin?
Look at it from the perspective of the bimini fabricator and customer.
Option A - Bimini Skin
1. Cut holes. 2 minutes
2. Add boots. $5 parts
, 13 minutes.
, 15 minutes labour, add $50 to the price
. Bimini fabricator makes a decent wage and profit.
Option B - Bimini Mounted Backstay
1. Review vessel design. 15 minutes
2. Beef up bimini attachment points. $100 parts, 6 hours labour.
3. Fabricate bimini bow with welded back stay and vessel attachment points (rather then set screw fittings). $250 to SS welding shop.
4. Limit bimini bow design to be in-line with backstay. No cost, but PITA.
$100 parts, $250 sub-contract welding, 6 hours, add $2000 to price
99.99% of prospective customers will opt for the $50 option vs the $2000 option, as rain leaks
in all biminis and enclosures from somewhere anyway.
