We have a 1975 40''Northstar 80/20 Ketch (also know as the Spice Islander and Hughes 40)- and would appreciate any personal experience with the Spartite 2000 Mast Wedge Replacement System. Does it replace the rubber partners - does it leak and/or does it need a mast boot on top of it? Does it transmit shocks from mast to hull or hull to mast? Our main mast is massive - Sparkman Stevens Design We will be gone for about 6 weeks - from April 14 - so any requested response will be delayed until we get back. Thanks in advance for any info.
