The Fleet's Varying Saloon Ceiling Heights

It was during a conversation with Craig Smith, Rose Bud #34, that I realized that the floor heights of LNVTs vary. Craig's experience was first hand—his head hit the ceiling in some tugs but not in others. He specified is his purchase order that #34's ceiling was to be no higher than hull #22's. Here are two data points as measured just forward of the companionway hatch in the salon: #28 is 6' 1-1/2" and #2 is 6' 3-1/2".

An LNVT 37 is Actually 36'-10"

The actual length of a 37' LNVT is 36'-10" per Bob Allnutt, Victory #2, who dropped plumb bobs from the bow and stern and measured between them.

How to Remove the Companionway Hatch

Per Jamie Hansen, Philbrooks Boatyard, Ltd., this how to remove the companionway hatch:

To remove the fixed panel of the aft sliding hatch there are a few steps needed to take. There are several wood plugs on the top edge of the panel. After removing them, screws below can be removed. This may be enough to remove the panel. If not the hatch will need to be cut along the wood joint around the edge of the hatch frame. Once cut the top panel will be loose.  To re-install use a brown caulking on the joint and screw the top back on the hatch frame. New teak plugs can then be glued in and sanded flush.

A Replacement Window Channel Made by

Per Jamie Hansen, Philbrooks Boatyard, Ltd., has stainless steel window channel (621-4471) which fits an LNVT's 10mm glass. It costs $47/8' + shipping from Canada. He describes the installation process as follows:

The windows are made with two stainless steel frames that are inset into an outer frame that is attached to the cabin side. The inner frames are held in with small flat head machine screws under the gasket material. After the old gasket has been cut out and screws removed the frames can be pulled out using small pry bars or tapped with a wood block and hammer. Be careful not to bend or kink the frames during the removal step. Be sure to clean the inside of the metal frames well to prepare for the new gasket material.

To bend the new gasket into the frames can be hard so we have come up with a helpful method to obtain a good fit. Using the frames as a template, trace the inside shape onto a piece of ¾” plywood or MDF. The cut out is a good jig to bend the gasket around and give you the right size and shape to fit the frames. Slots are cut into the gasket before being installed to create the drain holes. The track can be glued back into the frames with silicon as well as the frames into the openings on the boat. Tape can be used to hold the gasket in place while the silicone dries over night. Be sure that the new screws attaching the frames are not in the way of the operation of the sliding pane of glass.

Pilothouse Drop-Down Windows are 6mm Thick

Per Jamie Hansen, Philbrooks Boatyard, Ltd., the glass in Tess II's #22 drop-down pilothouse windows is 6mm thick. Why isn't it 10mm thick like the rest of the glass aboard an LNVT? Maybe because 6mm glass weighs 7 lbs less than a comparable 10mm pane.
