I watched the videos, they are well done. Below are some critiques based on what was stated in the videos:
What I don't understand is why they place alternating layers of glass mat in the below-the waterline hull. Glass mat does nothing for stiffness, adds an enormous amount of weight to the laminate as all it does is soak up resin like a sponge, and adds bulk. One possibility is that Hunter is using the mat to add bulk cheaply in lieu of a core
I have no idea what they are talking about with their 'rudder tube' - the rudder
is typically supported with a bearing/bushing at the hull, and another at deck
level (at least for a wheel-steered boat), and there's no need for a 'rudder tube'. Perhaps they are trying to avoid installing a gland above the lower bearing.
I'm not a fan of hull liners, for two reasons: the bonds of bulkheads to hull are not primary chemical bonds, but rather mechanical (glue) bonds. Normally a primary bond can happen with a week of layup
, and after that the polyester or epoxy
has cured sufficiently that a chemical bond is no longer possible.
I've cut away enough interior
liners to get at the hull so that by now I truly do not like liners. I don't have a liner on Beetle Boat (downside, I get to see all the wiring
and hydraulics and bolts, all the time, as they are exposed), but I do carry a small fireman's axe/wrecking bar that will remove the interior in minutes to get at a hull failure; it was recommended to me by a friend that had that problem (poked a hole through the hull) and he removed the entire head in less than 60 seconds, toilet & cabinets included.
Hunter makes an amazing statement that the Plexus glue 'chemically melts' fiberglass
& resin into one structure... perhaps this is true, Plexus makes the same claim. I've never heard of 'melting' resin and fiberglass... I'd want to know more.
Hunter points out that they use plywood
blocks for the deck core
, but they're using balsa for the hull core - would be lighter to use balsa throughout. And then they point out they use aluminum
for hi-load areas (which is odd, normally plywood
is used as the core material for hi-load areas, with an aluminum
backing plate). Using aluminum as a hull core isn't necessary bad, but it sure is difficult to route-out if you have to. The downside to encapsulating aluminum in glass is if the aluminum corrodes, the alumninum oxide is thicker than the initial aluminum, and will burst/crush the deck laminate.
Mechanical and decking:
they don't mention using 5200 on the keel
, though it would be typical to set the keel
Hunter seems to have done well, and their boats are better-constructed than they were 15 year ago.
For the record
, I own a 1983 IOR two tonner built by Charlie Morgan
to a Bruce Nelson design - no liner, solid glass below the wateline, klegecell and divinycel core topsides and deck, all systems are visible and serviceable. And no doors, either - one 45 foot tube, from the mast
I can see (with a flashlight) forward to the stem fitting bolts all the way aft to the engine exhaust
