    Anyone near Burlington, VT?

    BC - Where is the boat?  Floating or on the hard?  Name of boatyard / marina?  Lots of options near Burlington but not all are easy to get to.  If Clean can do it, that's great, but maybe a local is already nearby.  Just a thought. Best of luck

    Online Fasteners? 304/18-8 vs 316 SS

    +1 for BoltDepot.  Good website / Fast shipping / Helpful staff.  You can buy in "eaches", boxes, or bulk They also sell hard-to-find extra thick (0.125in) stainless steel washers and fender washers.   BoltDepot Extra Thick Fender Washers I use McMaster too but they only sell boxes (not "eaches")

    Best way to add a diverter for fresh water flush and winterization

    I made a special cap for my strainer for flushing and winterizing but they are available to buy from Defender for Groco strainers: I found the "flush cap" option to be the easiest / most robust solution for winterizing.  No adding parts /...

    105+206 = Hot Pot

    Dude - That is bananas.  5:1 by weight is at the very low end of the acceptable range, there is little room for error left.  Using 5:1 by weight instead of 5.36:1 puts you off proper stoichiometry by ~7%.  If you are going to spend the time to weigh with a gram scale, follow the supplier's...

    Gelcoat oxidation fix

    I found a website many years that answered these questions very thoroughly.  The website is no longer active but I made a PDF of the text for my own records.  I am attaching the PDF for you to review.  I have used this methodology to restore a few boats now and fully endorse it.

    105+206 = Hot Pot

    Make sure that you are using the correct mix ratios.  For 105 / 206 the mix ratio BY VOLUME is 5 to 1.  The mix ratio BY WEIGHT is 5.36 to 1. Resin has a higher specific gravity (density) than the hardener, hence the difference in volume / weight ratios. Attaching a pic of the data sheet:

    Lewmar EVO vs. Ocean

    For two Lewmar Ocean 30 Winches: West Marine $979.99 + sales tax + free shipping Defender $541.20 x 2 = $1082.40 + sales tax + shipping ($27.15) Sales tax differences state to state make it more complicated but it looks like West Marine deal was a little better in this case. Tough call...

    3M VHB tape or Dow 795 to afix acrylic windows?

    I found this article helpful using tape to attach windows All VHB are not created equal.  Use the right one for your substrates and use the adhesion promoting primer for best results. I found reasonably priced VHB in small quantities on eBay.

    Mirage 24, anbody know these little boats?

    My first keelboat was a Mirage 24 (nearly 20 years ago).  Very solid boat, not much to go wrong.  The boat has a rather strange semi-balanced rudder set up.  There is a split bronze fitting in the exterior hull that houses a lower plain sleeve bearing.  The rudder has a corresponding square...

    In the US, you can buy pre-treated UHMW PE material by the meter from: Sintered material is best. Durasurf 2001 or 4001 is a good choice. I don't recommend the extruded/HDPE material. It is harder to bond sometines and is not as abrasion resistant. +1 on the...

    UHMW PE (ultra high molecular weight polyethylene) is the base material/running surface for 99.9% of the skis and snowboards made in the last 50 years. Some people call it Ptex, but that is a brand name. Properly prepared UHMW PE bonds very well to epoxy. To prepare for bonding, the UHMW PE...

    Sailing for vision impaired

    I am a centrally blind sailor and have tried many things over the years to be able to keep sailing. I don't race any more but I still daysail in the cruising boat as much as I can. Mostly light air, nice weather stuff on a large lake. Two suggestions: 1 - Really big tell tales are great. I...

    5/8" Divinycell H80

    Consider using Gurit CoreCell M80 foam instead. It is a better core material and is easier to get. Noah's Marine online store in NY USA has 16mm (0.630in) x 24in c 48in sheets for $63. This is the TC version, which means triple cut, if memory serves. It has knife cuts part way through it to...

    Nonskid options for older Melges 24

    Cottage Industry Dagger Board Construction

    Against my better judgement, I am going to drop in here to make a few points and supply some more info. I am the guy (nerd) who provided technical support to Dan on this project. I want to try to explain a few of the technical choices made. This was a "fun" design/fab project with some very...
