Re: Interested in your Harbour

Hi, could you calculate the sail for me using the standard Dragonforce sail area? I had to tilt the mast aft on another boat, and it works great now also used dragonforce sails.

Re: Mercantic motor

Hi Roy, the main body of the motor is 80 mm and about 45mm wide, it has two output shafts a straight through one and a reduced speed one that the propshaft is connected to.

The sticker on top is unreadable so no idea personally

I hope that helps identify it

Take care

Bryan

Re: Mercantic motor

Yes mine has two screws in the output end. It turns when you turn either shaft so will hopefully work once I get the battery. Ive not heard of these before but am fairly new to rc boating as I was far too young in 1967.

Re: Interested in your Harbour

What do you have in your harbour? I see nothing posted.

Re: my schooner

Royce,
If I sent to you the sail plan would you be able to calculate the amount of ballast needed for my vessel? Math is not one of my strengths🤔

Re: my schooner

I glued 3lbs inside the hull of lead pellets and on the exterior there is a 1/2”x1/2” sq bar 12” long, screwed into the oak keel.
There will not be a centre keel board with a bulb at the bottom because of the weeds found in our lakes and ponds.

Those four sq.bars taped in position bring the sight to 9.4lbs.

5.1/4” draft
4 1/2” waterline to boom

Main mast from deck to top 24 1/2”
Fore mast 20 1/2”

The sails measure:
Main
Foot 11 1/2”
Leech 19”
Luff from tack to throat 14 1/2”
Head peak to throat 7 3/4”

Fore sail
8” Foot
13” Leach
11 1/4” Luff
7” Head

Jib
8” Foot
18” Leach
16” Luff
