Shown here are various views of Tehani. I have included a short
description of what is unusual about this design. The short version is:
collision bulkhead, metal hull, long waterline, performs well when loaded,
strong rudder and protected propeller, keep holes in deck to minimum, all tanks
and batteries below floor, hard dodger, no exterior wood, good ventilation, use
space efficiently, hefty rub-rail, and be able to deal with two anchors. Many
of these things are available in production boats but most often in boats above
42' in length. It is the combination that helped me decide to go with a custom
(41856 bytes) Hard dodger, rub-rail, davits, anchor sprit all welded on.
The boom is lower at the goose-neck so that flaking and covering the
main is easier. All port-holes are opening. The inner fore-stay is
removable and only used for the storm jib. The boat is 38'3" long
and has a waterline of 35'2". The hull shape is what is called a
"radius chine" which means the boat was designed with a single
chine which is then rounded to a constant radius.
- Anchor locker,
(38651 bytes) Shows watertight collision bulkhead, anchor locker
bottom, drains to bow, locker behind collision bulkhead is where
windlass motor is, snubber welded on for anchoring, 13 degree plumb
- Anchor locker,
(41699 bytes) Windlass is run clockwise to raise starboard anchor,
counter clockwise for port anchor. Twin fore-stays for roller furling
genoa and hanked on 100% jib connect to a wide chain-plate welded to
the stem. The chain-plate for the inner fore-stay is right in front
on the windlass and is welded to the collision bulkhead below.
The inner fore-stay has a link about 2' up and it is normally stowed
alongside one of the forward lowers and used only for the storm jib.
Mud dams prevent mud from running down the deck. My original design
is shown here (62324 bytes).
- Cockpit and dodger,
(30804 bytes) The cockpit is a conventional "T" shaped cockpit with
steps on each side of the wheel for docking. A sail locker on the
starboard side and three lazarettes behind the wheel. One lazarette
is sealed and vented out the transom for propane bottles, the other
holds the soft-pack life-raft. The stern has a small cutout for one step,
the two steps above it are welded on. The cockpit drains via two 3"
drains right at the "T", these tubes are aluminum and welded to the
transom and cockpit floor.
- Hard dodger, side view
(58004 bytes) The dodger has a hard top welded on. The sides
are Sunbrella with Lexan windows. The sides have a bolt-rope
at the top and bottom that fits into a "C" track along the top and
bottom of the dodger. The forward windshield is Lexan
with a 30" wide hatch in the middle for airflow. The forward coaming
doubles as a dorade box. Solar panels will cover the top of the
dodger. The bimini just overlaps with the aft foot or so of the
dodger. The top of the dodger is 5'2" from the cockpit floor for
good visibility. The traveler has to be far enough forward to clear
the opening hatch in the dodger.
- Mast area, top view
(33270 bytes) One big dorade box at the base of the mast doubles
as a step for putting on the main-sail cover. Blocks aft of the mast
are for the main-sheet and reefing lines. The reefing winch aft and
starboard of the mast is for cranking in the clew of the main-sail.
The small hatch forward is over the head, the small hatch aft is
over the "L" settee in the main cabin (vent for kerosene reading
light) and the medium hatch aft is over the table in the main cabin.
(20567 bytes) The starboard side of the fore-cabin folds up, there
are no cabinets underneath. There is enough room for two bikes and
and windsurfer shortboard (8'6") here.
(49400 bytes) Pretty conventional, wide enough for one person and
not too big so you get thrown out or slammed. Mechanical refrigeration,
(42285 bytes) Mast is outside the head, the floor is an aluminum pan
with a crease in it to drain into the shower sump.
- Main cabin
(34472 bytes) "L" shaped settee on the port side. Permanent table in
the middle with leaves that fold up. An extra set folds up along the
galley bulkhead (port side). Bookshelves line each side.
(48489 bytes) Almost a double quarterberth. Sit on forward part of
quarterberth for chart table. The port side of the quarterberth can
be removed for side access to the engine.
The compromises/mistakes made on this design are:
- We were unable to get the fuel tanks below the floor. About 1/3 of them
ended up below the floor. I think this is due in part to the plumb bow which
makes the hull shallower. I was advised against tanks in the aft part of the
keel because they are difficult to maintain. We did manage to get all the
water tanks (100 gal so far) and batteries (four 8-Ds, a start battery, and a battery up forward for the windlass) below the floor.
- I have had second thoughts about the anchor handling system. If I had
to do it again I might put two windlasses in. I can still do this with some
minor welding inside the anchor locker. The locker is huge so space is not a problem. One mistake is that the chainplate for the inner forestay is in front of the deck mounted windlass, I should have put it behind. This could be fixed now but we are going to try it for a few seasons first.
- We did not pay that much attention to water drainage when we built the
deck. There are two spots where water collects: on the inside of the genoa
track (since it is welded on continuously) and in the corners of the cockpit
settees (they are dead flat). We are planning on fixing these by putting in drains next time we repaint the deck.
For the most part, we are completely in love with this design. It is a joy
to work on something that is exactly the way you want it. An aluminum boat is
very solid and it is noticeable when walking around on deck or mounting the
interior structures. The aesthetics of the dodger are perfect for us and we
think it really adds to the profile of the boat.
