No. 49 - June 1982


Len Forkes (#658)


Dear John (Charters) #1000


About a year ago I visited you in your office and we discussed among other things the intention of my designing a raising device for a Tanzer 22 mast. You were most helpful and generous with your advice which I appreciated. I did agree at your request to advise you of how I made out. I have enclosed some sketches and instructions.


The device worked very well both in raising and lowering. I only ran into two small problems when raising, none of which were the fault of the equipment.


1. The backstay fouled the rudder pintle.

2. The starboard upper shroud caught under the Genoa cleat.


These points I will look out for in the future. The first time I raised the mast I was 65 and did so during a 25 - 30 mph wind. The only comment from the single bystander was "You made it look so easy".


Bill of Materials

2 - legs 1 1/4" or 1" x 103" steel tubing

1 - base 1 1/4" or 1" x 67"

2 - pads 4 x 4 x 2 1/8 – 1 15/16 pine 

1 - double eye formed from 3/16 or 1/4 cold rolled rod

2 - U-bolts 1/4 x 2 1/2" - 3" (as for T.V. antenna mast)

4 - S-hooks 5/32 x 2" (Close one loop)

2 – 1/4 x 2 3/4 stove bolts or equivalent


Detail description and operation

A device to raise or lower the mast of a T22 by oneself. No fittings to fasten to boat, no holes to drill. All ropes and tackle available onboard.


Assemble as per sketch Fig. A. May be stored by removing one bolt at foot of leg and folding. Place mast on crutch and insert Mast Hinge bolt. Secure Back Stay. Prepare Forestay and Upper shrouds for fastening.


Place A-frame Fig. A. onboard with Base between Mast Step and fore hatch Fig. B. Insert wooden filler as required to prevent movement of base between mast step and fore hatch. Adjust pads so that base clears hand rails.


Shackle main sheet to foreward loop of double eye and to after hole of stem head fitting. Reeve line through after loop of double eye and pass around Mast head spreaders. Rake A-Frame aft in order to have mast come vertical when main sheet is "chock-a-block".


To steady mast while being raised (or lowered) select a light line preferably ¼” and pass end through closed loops of two S-hooks. Form a figure of eight knot or bowline to prevent line from withdrawing. The S-hook at end of line is hooked into the terminal fitting at end of lower shroud as shown in Fig. C. The other S-hook is hooked into chain plate hole for the lower shroud. Repeat on other side.



You are now ready to raise the mast. Haul in on Main Sheet

, checking that nothing is fouling, during raising. You may stop at any point by seizing the Main Sheet or taking a turn around the Bow Mooring Cleat.


At the same time as the Mast is being raised keep some tension on the steadying lines to prevent the Mast falling sideways.


When the Mast is vertical secure the Main Sheet and steadying lines. Secure Upper Shrouds to Chain plates and Forestay to Deck Head Fitting.


To lower, reverse procedure.


The total cost of the device to me was under $10.00. The tubing was obtained from a scrap yard and the U-bo1ts and S-hooks were standard hardware from any Hardware Store.


(Peter Browne #614 has a similar set-up which I saw in action this spring. It is indeed an excellent way to single hand your mast up or down. Peter used his spinnaker pole in place of the two metal tubes.)
